Extruding outline drawn on 3D solid

Tool(s): Extrude

To extrude the outline drawn on the surface of a 3D solid

• You have already created the 3D solid.
• Set the view to 3 Viewports.

1. Click Extrude (How).
   

   Activate Extrude in one of the following ways

   • Menu bar: Create Bonus Tools 3D Modeling

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

   3D Modeling

2. Using the context toolbar, you can specify how the extruded solid behaves:
   • Always add solid is not active (default setting): if the extruded solid intersects or penetrates an existing solid, the extruded solid will be subtracted. If this is not so, the extruded solid will be added.
   • Always add solid is active: the extruded solid is always added.
   • New element is active: the extruded solid is always created as a new element.

     Example

     Note: The preview shows how an extruded solid behaves: red solids are subtracted; green ones added.
     New elements are displayed in the current line color; they do not change any existing elements.

3. Specify which outline you want to enter on the Extrude Context toolbar:
   • Extrude Polyline
   • Extrude Spline
   • Extrude Rectangle
   • Extrude Circle
   • Extrude Polygon
4. Click the reference surface where you want to draw the outline.
   The selection preview shows the local X, Y and Z directions of the selected surface (work plane).
5. Draw the outline in the same way as you would draw a 3D Line or 3D Surface.
6. To extrude the outline, move the crosshairs into the required direction and click the target point. Use the viewport with the view that works best for you.

   or

   Enter the value for the Length in the dialog line and press ENTER to confirm.
   The value applies to the local coordinate system of the selected surface.

   Note: The Length must not be less than 1 mm.

   Note: The extrusion path is always perpendicular to the reference surface.

   Allplan extrudes the outline.
