This topic has been discussed over and over, but I'm at this for more than one full day: relations.
The drawing is part of a school project designing an autocrane for an inland cargoship. The rear flange of the inline boom has one tiny leftover line. This line prohibits extrusion of the flange part understandably. Trimming it also removes a bunch of relations. Trying to dimension the endpoint (the beginpoint of the leftover line really) to the origin somehow doesn't restore those relations. I have way to many dimensions in the drawing I suppose, but at least I got the sketch fully defined.
How do I fix this particular relation thing?
Thanks much, maurits
