pocket on additive pipe

Post by fpons »

Hi,
I'm trying to remove a segment from an additive pipe extension from a body. I have tried both a hole and a pocket on the desired position but all that I have managed is for freecad to "draw" the segment I want to remove (as shown on the image) but not remove it.
The green segment should not be there.

Not sure if I'm doing something wrong or if it's a bug. Any help on why this could be happening will be greatly apreciated.
I've loaded the FCStd file if needed.

PD: If this is not the correct place to post this question, please let me know.

Hi and welcome to the forum!

You have to draw all sections of AdditivePipe in the same sequence: start all with the inner loop and then add the outer or do it for all sections vice versa.

Hi, Thanks for the answers.
I redrew the object using all the recommendations and it worked as expected.

I gather from this that I had a measurement error somewhere creating a measurement mismatch...
I will definitely apply both recommendations on my future designs. I'm a bit rusty on CAD design and new to freecad as you must have noticed.

fpons, I noticed on your second attempt the pocket didn't cut into the radius, that might be what made it work.

Hi,
I tried reducing the radius as well before, and it didn't work. I'm sure it was an issue with my part dimensions.

Thanks.
