I am modeling a complicated piece of a pedestrian bridge concrete structure and am having difficulties creating a Loft. See attached model file.
My original attempt for modeling this structure was to use a guided Sweep, which resulted in geometry that was close but not perfectly accurate along the entire path (despite being guided, it still twisted a tiny bit). So I'm trying a Loft to see if that makes the geometry more accurate. The issue I am having is the usual "guide curve does not intersect profile". Here has been my workflow:
- Import path Points from an Excel file. Use the "Create Spline" feature between all points.
- Create two workplanes normal to the path; one at the start point, one at the end point.
- Import CAD profile on both sketch planes, using the start/endpoint of the path as the shared origin with the profile.
- Create Patches on both profiles so the Loft command recognizes them.
- Select the path guide curve.
A really confusing part of this is that sometimes the Loft works and sometimes it doesn't, even when I follow the exact same steps. The times that I have been successful, the geometry is not accurate; the loft necks down and is too skinny near the middle of the path. I tried adding more guide curves connecting multiple vertices of the profiles to constrain it more, but the issues I had originally only seem to be amplified and I can never get this to work.
Any thoughts?
