I'm trying to make a bike, but I want to use some weldments on the frame. I've already placed 2 weldments, but I can't find out how to place the third weldment. I wanted to use a groove weldment, but it doesn't work. I have already done a groove weldment on the frame, so I don't understand why the otherone doesn't work.
I just learnt a bit how to use weldments, but i can't find much information how to use it. I'll place my testframe in attachments. I hope someone can help me fix this or explain me what's the problem and how I should use weldments.
