Guided loft: Create a surface using multiple profiles

Description: 5 minutes; Lab exercise: 20 minutes

Select more than one profile to create a surface.

The following conditions apply for using multiple profiles:

The system will automatically sort and connect the edges selected for the profiles. With multiple profiles, OSDM will recognize when profiles have the same number of edges and automatically match the vertices.  If the number of vertices is not equal, you may want to split the profiles or use matchlines to get the desired result.

Lab exercise

  1. Save the file multipleProfiles.pkg on your system.
  2. Load the multipleProfiles.pkg file.
  3. Click Surfacing .
  4. Click Guided Loft in the Create Face section.
  5. Select the line as the Spine.
  6. Select everything else as the Profile Edges.
  7. Click Preview.

You may see a result like this,

There is a self-intersecting surface due to the orientation of the first profile. To fix the problem, click Reverse under Profile Edges and click any edge of that profile to reverse the orientation.

The system recognizes that each profile has three edges and automatically matches the vertices.

If the number of vertices is not equal, click Split At under Profile Edges to split the surface at each profile.
