How to control a sweep end profile.

Phil_G_1987

Is it possible at the moment to create a sweep that has a different end profile to the one it starts with?

To put some context in this I'm currently playing around and modelling a weldment frame piece with a 45 degree support between an L shaped piece. I can sweep from a side profile upto a point but at that point it simply intersects with the model. As this is a single piece I can't simply trim the geometry to the correct length and angle.

I've added pictures for reference

Sweep to surface shows the geometry, and geometry used shows the sketches I created to try this out.

If anyone has any tips/ideas to share about the best way of creating this in OnShape I'd love to hear them.

Thanks!

You could try a 'replace face'. Select the end of the swept tube and then the bottom of the top frame tube.

Currently no. What I do in this situation is to use a replace face to change the termination face at the end.

First, make your sweep


Then do a replace face on the end.  Choose the terminating face of the sweep as the face to replace.  Choose the terminating surface as the surface to replace with (may need to flip the alignment of the surfaces).



So for yours I would use the end face of the red part as the face to replace and the bottom of the grey part (I assume) as the surface to replace with.

Yup, that works!

Thanks guys! This got me exactly what I need . I found a way to get a similar end result, but not as neat by using the delete part feature and removing the top part protruding from the cross member.

Thanks again!
