"Odd" behaving Sweep... or is it me?

[raphaelgiudizio]

Hi, I'm trying to make a Sweep along a 3D path to make a frame. It's a very simple rectangle along a path actually. Now I get this twist, which I think has something to do with the 'normal' of the lines or something, I don't know. If included a picture, which should explain the problem, and I also included the drawing file.

Has anyone any idea how to solve this? I also already tried to make the frame of separate sweeps per line (so 4 separate sweeps) but than I run into other problems, maybe because I want to have some measurements of the construction sketch by a Variable Parameter.

Any idea's? thanks.

very clever, @TheCADWhisperer !

Just to clarify - I am not real happy with my "solution" but want to verify that I am on the right track.

Hi, thanks for your reply and attempt for a solutions. And ideed a clever idea, but.. :).. and here it comes. It would have been a fine solutions if I only wanted to make a rendering or something. When I need a cad drawing with actual measurements this doesn't work. Just look at the Variables I've made and set the "Raam_Curve" to something like 80 and the profile's all of the sudden become very big on the bottom and thin at the top.. So if I wanted to make a frame, let's say, out of steel, I couldn't have a tecnical drawing.

This will take a bit more work than you might expect.

I assume you want this as 4 Components.

Do you want butt joints or miter joints?

Hi, First of all, thank u so much for putting in your time. 

Further I know I'm might be a bit demanding .. 🙂  but in your drawing the profile's are not exacty neatly inline, which they have to be for my project. See attached picture I took from your drawing.

Now I might have an actual answer myself, Happy days.. Still working on the drawing at the moment but I'm very close, I think. Oh and they can be butt joints btw. And in my drawing the hole frame can be one component, ready for connection to other components with joints..I'll let u know..

Hi, in fact, hehe.. only half an hour later now, and.. tada.. it works. NOT with one simple sweep or pipetool or anything, but with a sweep/extrude per profile. In my original post/question I mentioned that this solution gave me 'other problems', but apparently that was just one referencepoint that was pointing to a previous body instead of a projection. This confused fusion apparently.

So I got what I need, and it's a lot more work than just one simply sweep but at least I can go on with the project I need it for. Now all the measurements are controlled by user parameters, so I can make the frame big or small and even the profile's thick or thin with only 5 parameters..and everything stays inline.

Thanks and have a good day all.
