Extrude along path

Module(s): 3D Modeling

Using Extrude Along Path, you create solids or surfaces by extruding an open or closed profile along a path.

Tip: Allplan executes the Extrude Along Path tool without deleting either the profile or the path. It is a good idea to draw the basic elements in a separate drawing file. You can then open this drawing file in edit mode and create the surfaces or solids in the current drawing file.

To extrude a profile along a path

• Draw the profile and the path.

1. Click Extrude Along Path (How).
   

   Activate Extrude Along Path 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. Select the profile you want to extrude.

   Note: The profile must be planar and continuous. It must not intersect. It can be open or closed. If the profile consists of several elements you cannot select with one click, you can use the Brackets to select them.

   Note: You can even use edges of existing elements for the profile.

   

3. Select the path.

   Note: The path must be planar and continuous. It must not intersect. If the path consists of several elements you cannot select with one click, you can use the Brackets to select them.

   Note: You can even use a path that does not touch the profile. In this case, select the start point and the end point of the path and move it to a defined point of the profile.

   

   If Allplan can process the geometry of the profile and the path, it creates a preview of the solid and opens the input options. Otherwise, it will issue a message.

4. Define the Profile rotation type:
   • None
     The profile does not revolve along the path.
   • Default
     The original angle between profile and path does not change.
   • Z-axis
     The original angle between profile, path and z-axis does not change. For example, think of a ramp in a parking garage.
5. Interior profiles lets you add additional edges along the path. This is useful if you do not use a polyline for the path.
   If you enter 0, Allplan does not create interior profiles.
6. If the profile is closed, you can select the Closed volume option. You can choose to create solids or 3D surfaces.
7. After you have set all options, click Apply.

   Allplan creates the solids or 3D surfaces without deleting either the profile or the path.

   

   Note: Solids and surfaces get the color set on the Format toolbar.
