Thanks. I will look into that. I dont yet have the tree structure facility, but I know about it, just not sure how to install it.

I am ok building parts in Freecad but I struggle when editing parts. I often get an error that I cant understand or fix. For exmaple yesterday I tried to remove a pocket and an unrelated pocket became detached. Is there a video or something that would help me better understand the editing process?

I am used to seeing either "As Is" OR "Wireframe", but somehow when I now select As Is, I get both and I cant get rid of the wireframe view which is confusing!

Sorry if this is a newbie error!

I have a part which I want to replicate as a polar pattern, but as it is not a feature on a part I cant use the polar pattern feature or can I? The part profile was sketched in the YZ plane, then made into a pad. Then I want to replicate it 8 times around the Z axis but cannot find any way to do it.

Thanks guys, Sketcher External works a treat. Selected the vertices and placed my sketch onto them. Then used Revolve to add my extra part and then fused them. Made a double helix by copying and rotating. This will be a cutout inside a tube to form an internal jacking thread that works over approx 1...

I want to pick up on the end face of a swept object and sweep it with a new path. But the end of the object is not a sketch so how can I convert it to a sketch? Or, I can generate a new sketch to copy the face but I cant find a way of picking up on the existing points.

I hope I made that clear.

Thank you. I dont have that WB available on mine (0.16 R6706). But I would like to know why the draft move doesn't work in my application. I made an effort to learn it and it fell at the first fence so to speak. Disappointing, and not good for the ego!

I have created two shapes, one is a 45 deg pipe bend, made using sweep of two shapes then cut. Another is a trumpet (ram pipe) using a profile rotated around axis. The idea was to then align the trumpet to the 45 deg face by moving the trumpet to make one assembly . But I could not find a way to ali...

Great thanks, I needed that clarity of thinking. Not used mirror before so will add that to my experience.

Just one more thing I have problems with is editing. For example how would be best to change the length of the flange?
