Pierce 3D Surface

3D QuickSketch

You can use this tool to create a new 3D solid based on an existing surface of a 3D solid. Start drawing a closed outline. Then, this outline is assigned a height in positive or negative direction and depending on this direction, the outline is merged with or subtracted from the 3D solid.

To pierce a 3D surface

1. Press and hold down the ALT key and click with the left mouse button in the workspace.
2. Select the Pierce 3D Surface mode.
3. Enter the base of the new solid based on a surface of an existing 3D object.
4. Do the following:
   • To create a base of any shape, press and hold down the ALT key and enter the outline of the surface using the mouse.
     The outline is displayed in green.
   • To create a circular base or a base parallel to the coordinate planes, press and hold down the ALT and CTRL keys and draw the outline of the surface using the mouse.
     The outline is displayed in blue.

     Release the ALT (and CTRL) key and enter the height of the object (perpendicular to its base) in positive or negative direction in the dialog line or by using the mouse.

     A new solid is created based on the surface of the existing 3D object.
