5.1.4    Combined Polygon Element

The Draw->Combined-> Circle/polygon command from 2D Window menu indicates manual drawing of a combined circle or combined polygon element.

Its bottom and cover are draw once as a circle or polygon. Click the left mouse button two times to mark its centre and radius or by entering the coordinates from the Keyboard Entry dialogue. The bottom is being introduced on the current level, with the current height and with current medium. The cover is being introduced at the top of the bottom, with the 0 height and with current medium. To change current height, level and medium settings please use Define Level dialogue. The circle is approximated by a regular polygon with the number of sides (sectors) defined by the user. The choice of the number of sectors gives the Circle/Arc Sectors dialogue.

After the element is introduced its bottom and cover can be selected separately, and cover can be edited without influencing bottom. Please invoke Select Element dialogue and doubleclick over the line in which the cover part is listed.

Now click over the introduced circle, move it and click again. You can see the modified shape of the combined element.
