I'm trying to thicken a surface such that is it normal to the surface (figure 1). But I get an error saying that the feature cannot be created as defined, and suggestins using Special Handling Definition (figure 2). When I select Automatic Fit, the thickening is not normal to the surface (figure 3). Do you have any troubleshooting tips? Perhaps I need to investigate the quality of the surfaces i created? Thanks for your help!
I tried to offset my boundary blend (see newly attached image, the extending flange on the left is separat from the hemisphere). As you can see, there is a gap between the two surfaces. Is there an easy way to connect the flange to the hemisphere?
My 2 cents is:
thicken works and does provide a good tool for defining constand thickness parts (we make deep draw sheet metal stamped parts).
If a thicken feature fails try "options>exclude surfaces" and see which surfaces, when excluded, allow the thicken feature to work.
Make sure all the radii are larger than the thicken feature (only matters when thickening the radii inward)
The biggest help when thickening complicated surfaces is play with model accuracy trying to get the tightest possible accuracy.
