Hi Drakonsden, sorry I don't really understand what you're describing.

> you could also select a point that would follow the path?

Well, when you do a sweep the entire shape follows the path, that's basically how Sweep functions - it takes a profile and marches it along a path to create a surface.

Could you maybe post an example of a situation where you're having a problem?

Maybe you are having a problem with "auto place" mode - if your profile is totally to the outside of your rail path (where the bounding box of the profile does not touch the bounding box around the rail), that currently activates "auto place" mode where the profile is moved to be centered around that rail.

That's so you can do things like draw a circle flat on the Top plane and then sweep it around any path curve instead of needing to carefully create the circle to start out perpendicular to the path curve initially.

But if you are getting that kind of centering in a situation where you don't want it, the solution is to make the profile curve actually touch the rail curve and then it will take the profile from exactly where it currently stands. You may need to either move the profile curve, or you may need to make the rail curve larger by using Offset or something like that so that it touches the profile curve.

If you could post your 3DM model file of the situation where you are having a sweep problem that would probably help me to understand better.
