I used to know how to do this but it's been so long my method doesn't seem to work anymore. How do I create forging draft or what was refered to many years ago as oscillating draft. I'm a SW2004 user.
I have a very simple part which I want to create a surface loft using 3 profiles each with a pierce relationship and a guide curve. Once the loft is created I would remove the material in front of the lofted surface using a surface cut. See the images below
This is what I end up with when I create the loft
What I am looking for to happen is the following (after the surface cut)
The image above is taken from a paper I wrote years ago when I worked in the Forging Industry and at that time I was using SW97or 99. So I know it can be done...I just don't remember how to do it.
Well, the interface has changed quite a bit since 2004 but, if memory servers, those are loft handles. In the absense of guide curves or centerlines, they control where the sections connect to eachother. It's especially useful if your loft sections don't all contain the same number of vertices.
If I undestand your design intent, your original was probably created as a sweep with a constant normal for the profile and a guide curve instead of a loft.
