Pocket at an angle

Post by Umayer »

Hi,

I want to perform a pocket at an angle like in the link below. Is this possible?

This is a long winded way of doing it, but I cant find away to angle either a pocket or a pad directly in v015 or v016.
It should be possible with an angled projection in v017 but I haven't worked this out yet.
I would hate to try and mill this in any common metal.

Maybe you need a special feature, go into Macros_recipes and Code_snippets, Topological_data_scripting.

Hello mario,

With your method, because the sketch is not on a plane parallel to XY, the arcs in the sketch do not produce cylindrical surfaces, but elliptic faces.

All of us need to relearn the software. But it's going to be worth it. (I personally hope we can suggest UI improvements, but I'll try to understand the current UI fully before suggesting changes)

Hi,

Thank you all for the suggestions. I think stated my question in the wrong way.

In the image I've attached, you can see that I did a pocket of an half circle. What I want to do is make this pocket a "90 degree turn" to the left.

EDIT: I just found out that in Catia you can use the "Slot" function to achieve this. If this is possible in Freecad, I would appreciate it if someone can tell me.

I managed to get it to work. I used the sweep function to get the shape, now I'm trying to cut the part but I keep getting an error.

Sorry for not responding to your new updated question, but I am playing with 0.17 and used pocket to face with plane as limiting face. Some issue with co-linearity where plane and sketch intersect(moved plane down 1 um)

Could you please post your Freecad file of your last image, quite hard to figure out what you are after
