Are polygons always in 2D

Draw 2D polygons

Polygon

With the Polygon tool (“Construction” tool palette) you can draw open and closed polygons with up to 4000 corner points. An open polygon, also known as a polygon course, is a polygon that does not have a closed outer edge, i.e. where the last point does not lie on the starting point. You can also use the polygon tool to create polygons from closed areas that are delimited by one or more objects (lines, rectangles, polylines, polygons). If one of the objects is round (circle, circular arc), a polyline is created.

Methods

As soon as you activate the Polygon tool, the following symbols appear in the method line. The “push / pull” method also appears in 3D views.

 

With corner points

You can use this method to draw closed and open polygons. Open polygons also have an area and can be filled with a filling. The missing edge of the surface lies exactly between the first and the last point of the polygon. Polygons are drawn by clicking where you want each corner point. Closed polygons are completed with a click on the starting point, open polygons with a double click on the desired position.

 

TIP: If you press the Shift key or activate the snap mode "Align to angle", the individual edges of the polygon can only be drawn at angles of 0 °, 30 °, 45 °, 60 ° and 90 ° and at a definable angle ( see also here).

From enclosing objects

With the second method, you can create polygons from closed areas that are bounded by one or more objects (lines, rectangles, polylines, polygons). If one of the objects is round (circle, arc) or contains holes, a polyline is created. To do this, click with the filling bucket symbol in the area that is to be created. Vectorworks then creates a polygon with the settings just selected in the attribute palette.

 

NOTE: Hidden edges of objects are also considered to be boundaries.

 

If you want to create a polygon from several areas, you have to hold down the Shift key while you click on the areas.

 

TIP: You can also use Modify> Create Area (see here) to create polygons from areas enclosed by object edges.

From enclosed objects

With the third method, you can create polygons from closed areas that are bounded by one or more objects (lines, rectangles, polylines, polygons). If one of the objects is round (circle, arc), a polyline is created. To do this, use the lasso tool to draw a line around the objects that delimit the desired area. Vectorworks then creates a polygon with the settings just selected in the attribute palette.

 

TIP: The objects that limit the area must be completely within the drawn line. If you hold down Option (Mac) or Alt (Windows) while you drag the line, objects that are not completely enclosed are included.

 

Push pull

With the help of this method, you can expand a polygon to a depth body immediately after it has been drawn. The prerequisite for this is that the polygon is aligned with the construction plane (see here and here). Follow these steps:

  1. Draw the polygon using the method you want and leave it activated.

  2. Click on the polygon and move the pointer in the desired direction.

  3. Click again when the depth body is the size you want.

 

TIP: A planar polygon can be expanded at any time with push / pull (see here).

TIP: The height of the depth body can be changed with the forming tool or via the info palette.

TIP: If you draw a polygon on a surface of a 3D object and then expand the polygon while holding down the Alt key, a full-body addition or subtraction is generated from the two objects. The prerequisite for this is that the "Automatic" entry is selected in the display line for object alignment.

Create polygon via dialog box

A polygon can also be created by entering all the data in a dialog box. A double click on the Polygon tool opens the “Polygon” dialog box. Here you can enter the coordinates of the individual polygon corner points. The settings there are identical to those in the info palette for polygons (see here).

Edit polygon

The height and width of a polygon can be changed by packing and moving a modification point with the activate tool. However, you can only distort, enlarge or reduce the entire polygon. If you want to move individual points or individual sides, you must activate the reshaping tool. You can find more detailed information on how polygons can be modified with the reshaping tool from here.

TIP: A double click on a polygon with the activate tool automatically activates the reshaping tool.

 

TIP: If you hold down the Shift key while reshaping, the polygon is only enlarged or reduced proportionally. The ratio of height to width is then retained.

Change polygon with info palette

You can also change individual existing polygons by entering the relevant data in the info palette.

 

1 "Upper part" - This part of the information palette is identical for all object types and will be discussed in detail from here onwards. The name of the object is displayed here. You can also put objects on a different level or in a different class.

2 “Insertion point” / “Extension” - This is a schematic representation of the rectangle surrounding the polygon with nine clickable points (options). The fields x and y always refer to the coordinates of the option you clicked on. This allows you to change the location of the polygon. In the fields x and y / ± x and ± y enter the horizontal and vertical dimensions of the rectangle enclosing the polygon ("bounding box"). This defines the overall width and height of the polygon.

3 "Move" - ​​You can access the coordinates of each individual corner point of a polygon and define these values. Specify here whether you want to move the entire polygon (entry "Entire object") or only a certain corner point (entry "Point only"). Enter the new coordinates of the corner point under x and y (5).

4 "Point" - With these buttons you determine from which corner point the coordinates under x and y (5) are to be displayed. Click the button , the coordinates of the corner point in front of it are displayed. Click the button , the coordinates of the next corner point are displayed. Click the middle button , the corner point whose coordinates are currently displayed in the info palette is highlighted by a black point. This point disappears again when you release the mouse button.

TIP: You can also right-click on a corner point and select context menu> Activate poly point in info palette. The coordinates of the point you clicked are then displayed in the info palette.

5 “x” / “y” - You can define the position of the polygon by entering an x ​​or y coordinate value in these fields. Whether only the selected point or the entire polygon is moved depends on which entry is selected under Move (3).

6 “Insert point” - Click on this button to insert a corner point into the selected polygon. The new point is inserted exactly in the middle between the currently selected (4) and the next point of the polygon. You can change the coordinate values ​​of the new corner point after clicking on Next point under x and y (5).

7 "Delete point" - This button deletes the selected point of the polygon (4).

8 "Reverse direction" - With a click on this button you can reverse the drawing direction of the polygon so that the starting point is on the other side. To find out the direction of the polygon, you can activate Show direction (10).

9 “Close” - Activate this option if you want to close the polygon. The first and last corner points are then connected with a line.

10 "Show direction" - If you activate this option, Vectorworks will show an arrow in the direction in which the polygon was drawn. You can also reverse this direction (8).

11 "Points" / "Area" / "Perimeter" - Here Vectorworks automatically displays the number of corner points as well as the area and perimeter of the activated polygon.

Double polygon

With the double polygon tool ("Construction" tool palette) several connected parallel lines can be drawn at once.

  1. Determine where the lines should be drawn in relation to the guideline that you draw with the mouse (methods 1 - 4).

  2. Enter the desired distance between the parallel lines under Distance in the method line.

  3. If necessary, determine in the "Double line settings" dialog window (open via the fifth method symbol) whether you want to draw lines or polygons, the distance between the two edges and whether shells (i.e. additional lines or polygons between the lines) are to be created. If you have not yet drawn any double polygons, this window opens automatically.

  4. Click where the starting point of the double polygon should be.

  5. Set the corner points by clicking where you want.

  6. The pointer draws the left edge of the double polygon, parallel to the right of it the right edge is drawn.

  7. If you want to draw an open double polygon, double-click where the last point should be. If the double polygon is to be closed, set the end point of the last left edge to the start point of the first left edge and click once.

TIP: To ensure that the double polygon is properly closed, you must always place the last click exactly on the first point of the drawing process. If you have drawn the polygon using the "Left guideline" method, you must click on the starting point of the first guideline, which in this case lies on the left edge of the double polygon. If, on the other hand, you have drawn the polygon using the “Center guideline” method, you have to click again on the starting point of the first guideline, which in this case lies on the imaginary central axis of the double polygon.

 

With Modify> Merge, double polygons can also be merged later. You can find more detailed information on this here.

Methods

As soon as you activate this tool, the following symbols and a text field are displayed in the method line.

 

Guideline

With the first group of methods you determine how the double polygon should be drawn. Actually, you only draw a line with the mouse, the so-called "guideline". With the first four methods you now determine where the double polygon is drawn in relation to the guideline. The distance between the guideline and the central axis and thus to the two edges with the "Arbitrary guideline" method is determined in the "Double line settings" dialog box (see below).

 

Dialog window "Settings double lines"

Here you can make settings for drawing double polygons. So you have to z. For example, you can determine the distance between the two edges, whether lines or polygons are to be drawn, or whether you want to create additional lines or polygons - so-called "shells" - between the double lines. If you activate the Double Polygon tool for the first time, this dialog box opens automatically.

NOTE: All the settings you make in this window apply to all double lines and double polygons. Objects that have already been drawn are of course not affected by changing these settings. However, all newly drawn double lines and double polygons will have the settings made in this window.

 

1 “Distance” - Here you enter the distance between the two parallel lines.

 

2 "Guideline" - In this field you can define the distance between the guideline and the central axis of the two edges. This value only has an influence on the drawing of double line polygons if you have activated the "Any guideline" method.

 

3 "Lines" - If you activate this option, two individual parallel lines are created.

 

4 "Polygons" - When this option is activated, closed polygons are created that are filled with the current fill pattern.

 

5 "Lines and polygons" - If you activate this option, two individual parallel lines and a polygon with invisible boundary lines are drawn. The two lines and the polygon can be activated and changed individually.

 

6 “Shells” - Click on this button if you want to draw further lines or polygons, so-called “shells”, between the double lines. The "Shells" dialog box appears. The settings that you can make there are the same as in the "Wall Settings" dialog window ("Structure" tab, see here).

"Distance"

Here you enter the distance that the two parallel lines should have from each other.

Regular polygon

Using the Regular Polygon tool (Tool palette “Construction”> sub tool of “Polygon”) you can draw regular polygons with up to 4000 corners. The objects created with this tool are not of their own type, but rather polygons, the sides of which are all the same length.

The objects created with the Regular Polygon tool are of the polygon object type. Regular polygons cannot therefore be created by entering data in a dialog window. Regular polygons are reshaped in the same way as polygons with the mouse or via the info palette (see here).

Regular polygons are drawn with the help of a guideline.

  1. Select the method you want (perimeter, incircle or side length).

  2. Enter the desired distance between the parallel lines under Number of corners in the method line.

  3. Draw a guideline to define the circumferential or incircle radius or the length of a side, depending on the selected method. You can also enter the dimensions of the polygon directly into the object dimension display while drawing.

TIP: If you hold down the Shift key while drawing or if the snap mode "Align to angle" is active, the guideline can only be drawn with an angle of 0 °, 30 °, 45 °, 60 ° and 90 °.

Methods

As soon as you activate this tool, the following symbols and a text field are displayed in the method line. The “push / pull” method also appears in 3D views.

 

Defined by perimeter

With this method, a regular polygon can be constructed by drawing the radius of the circle surrounding the polygon.

 

TIP: If you press the Option key (Mac) or the Control key (Windows) while drawing, the guideline defines the inscribed radius. This variant corresponds to the second method.

Defined by an inscribed circle

With this method, a regular polygon can be constructed by drawing its inscribed radius.

 

TIP: If you press the Option key (Mac) or the Control key (Windows) while drawing, the guideline defines the perimeter radius. This variant corresponds to the first method.

Defined by side

With this method, a regular polygon can be constructed by drawing one side of the polygon.

 

TIP: If you press Option (Mac) or Control (Windows) while drawing the guideline, the regular polygon is mirrored on the guideline.

 

Push pull

With the help of this method, you can expand a regular polygon into a depth body right after it has been drawn. The prerequisite for this is that the regular polygon is aligned with the construction plane (see here and here). Follow these steps:

  1. Draw the regular polygon using the method you want and leave it activated.

  2. Click the regular polygon and move the pointer in the direction you want.

  3. Click again when the depth body is the size you want.

TIP: A planar regular polygon can be expanded at any time using the Push / Pull tool (see here).

TIP: The height of the depth body can be changed with the forming tool or via the info palette.

TIP: If you draw a regular polygon on a surface of a 3D object and then expand the regular polygon while holding down the Alt key, a full-body addition or subtraction is generated from the two objects. The prerequisite for this is that the "Automatic" entry is selected under Object orientation in the display line.

Measuring / measuring

With the measuring / measuring tool (Tool group “Architecture”) you can construct the outlines of oblique polygons precisely without knowing the dimensions of the angles. Measuring / measuring enables the construction of exact polygons.

  1. Sketch the outline of the polygon.

  2. Activate the "Define edges" method.

  3. Enter the exact edge lengths in the dialog box that appears.

  4. Activate the "Define diagonals" method.

  5. Draw the diagonals in the polygon and enter the exact length values ​​in the dialog box that appears until the polygon is defined by all triangles.

  6. Based on these values, Vectorworks constructs the exact polygon.

Methods

As soon as you activate the measuring / measuring tool, the following symbols appear in the method line:

 

Define edges

You can use this method to draw the outside edges of a polygon.

  1. Click where you want a corner of the polygon to be.

  2. Then release the mouse button, move the mouse and click roughly where the next corner point of the polygon should be.

  3. As soon as you click on the drawing area for the second time, a window appears in which you can enter the exact edge length.

In this way you first draw an approximate outline of the polygon.

 

Define diagonals

If this method is active, you can convert a polygon that was drawn with the “Define Edges” method - in which the lengths of the outer edges, but not the angles, are precisely defined - into a mathematically precisely defined polygon by assigning the diagonal lengths. You can define the angles by defining the necessary diagonals.

  1. Click on the corner of the polygon, hold down the mouse button and draw the desired diagonal.

  2. Then release the mouse button and enter the desired value in the dialog box that appears.

  3. As soon as the polygon has been divided into triangles, a dialog box appears with the message “The polygon is completely defined”. (This is the case as soon as the polygon has been broken down into triangles by dragging diagonals).

 

TIP: This method is also based on "normal" - i.e. H. Polygons drawn with the polygon tool - applicable. As soon as you click on a corner of a "normal" polygon to determine the length of a diagonal of the polygon, a dialog box appears in which you are asked whether the polygon should be converted into a polygon created with the "Measure / Measure" tool should.

TIP: This method can also be used to change the lengths of the outer edges later. To do this, you simply have to trace the edge in question using the "Define diagonals" method and enter the desired value in the dialog box that appears.

Remove diagonals

If this method is active, you can remove a diagonal drawn with the "Define diagonals" method. All you have to do is draw the relevant diagonal while holding down the mouse button.

 

"Measure / Measure" dialog box

This dialog box appears when you have drawn an edge or diagonal with the Measure tool. You can then enter the required exact length of the edge or diagonal in this window.

 

1 "Length" - Enter the desired length of the edge or diagonal in this field.

2 "Done" - This button only appears for edges. Click this button when you have finished defining the polygon, i. H. if a line is to be drawn between the first and the last defined polygon point. A dialog box then appears in which you can enter the length of this line.

NOTE: In order for a polygon to be closed by clicking Done, at least three corner points of the polygon must be defined.
