Polygon

Task area 2D Objects

You can use this tool to draw a regular polygon.

To draw a polygon

1. Click Polygon (How).
   

   Activate Polygon in one of the following ways

   • Actionbar:Role Draft Task Design Task area 2D Objects

   • Menu bar: Create Draft

   • Palette: Tools Create area in the following module(s):

   Draft

2. If Polyline is selected in the input options, Allplan creates the polygon as one connected element that can be selected as a single entity with one mouse click. If is not selected, the polygon consists of individual lines that you can select separately by clicking or as an entity group by pressing the SHIFT key while clicking.
   

   An entity group is a group of elements which can be addressed as a whole. Polylines constructed in one step, for example, or symbols are entity groups. A group can be addressed as a whole by clicking one of the elements in the group with the middle mouse button and then left mouse button. Alternatively, select and hold the Shift key and click the element. Elements can be combined into an entity group even while being created (with the Assign Group Number tool) or later (with the Modify Format Properties tool).

3. You can apply symbols to the start point and end point of the polygon or draw the polygon as a pattern line.
   

   You can apply start symbols and end symbols to various 2D elements. To do this, you can use the Properties palette - Element area.

   • Select the symbol you want to use and define its size in millimeters.
   • Decide whether you want to apply a start symbol or an end symbol or both symbols by selecting the relevant the check boxes.
   • While drawing, you can change the symbol or switch it off at any time.

   Note: When you draw a polygon as a polyline, Allplan places the start symbol on the start point of the polygon and the end symbol on the end point of the polygon, which coincides with the start point. When you draw a polygon that consists of individual lines, each line gets a start symbol and an end symbol. Therefore, it is advisable to select either the start symbol or the end symbol.

4. Specify the center point or click a line to define the base line.
   

   • Click the point.
   • Align to points using the linear snap function and click the point.
   • Define the point by making entries in the dialog line.

   Tip: To find out how to enter points in Allplan, see Precision Drawing.

   Tip: The shortcut menu and dialog line provide tools and options to assist you in the process of entering points. For more information, see Tools and Options.

5. Enter the number of corners in the dialog line and press ENTER to confirm.
6. Complete the polygon in one of the following ways:
   • If you clicked a base line: Specify the direction in which you want to draw the polygon.
   • If you entered an even number of corners: Click the corner of the polygon or enter the width over flats (the distance between two parallel lines) in the dialog line and press ENTER to confirm.
   • If you entered an odd number of corners: Click the corner of the polygon or enter the corner radius in the dialog line and press ENTER to confirm.

     Tip: You can undo the entries you have made step by step by clicking Back in the Input Options.
