Re: trimming destroys relations, can't fully redefine elsewhere
Here is what I did
Changed a small line in this corner to construction geometry
Did a split on this line and changed the smaller/unwanted line to construction geometry
End result

Re: trimming destroys relations, can't fully redefine elsewhere
The first trick I don't follow. What small line in the upper corner did you change exactly? I didn't change this line obviously. Changing the line in the lower corner into a construction line I did. Such a simple solution (sigh).
However I cannot lay fillets around 3 of 4 flanges. Weird warnings start flying. The inserted bushings at the original face as well as the mirrored face I could fill in 1 go. Eight fills in one fillet. How come I can't do that with the flanges?
I will have to make changes to my design anyways. I intend to use 690 MPa steel. But the polar readouts give too much MPa in my setup. I used the polar moment at the centroid. Is that correct? My hand calculator returns 573, 719 and 929 MPa.
But would you know where my fillet problem originates?
Thanks maurits

Re: trimming destroys relations, can't fully redefine elsewhere
The upper side had an extra tiny line. Lower side I did split and changed both to construction (check attached video).
Now for fillet and mirror, the material is going in here and hence it is not letting you add fillets. I reduced the value to 4mm and it is better now.
.Attached is the updated file.

Re: trimming destroys relations, can't fully redefine elsewhere
I didn't notice this line because I wasn't looking carefully. Eventually I figured it out.
Also, I raised the seize of the largest beam from 300mm to 350mm. This allowed me to shrink the wall thicknesses and averall weight of the crane. I'm under 690 MPa now for each beam section. I need to ad more stuff like hydraulic cilinder and slew bearing. I haven't tested the assembly in simulation yet ...
Thanks very much Deepak for your assistance and instruction video!

... and it's still a little tight around the hinge part

Re: trimming destroys relations, can't fully redefine elsewhere
Sorry but I did not inspect your file carefully. From both the images and description, it sounds like you have an issue which I encounter now and then.
Easiest fix I find, once you've isolated the offending entities (it looks like Deepak identified where), is to set the lines to construction lines, and redraw cleaner entities on top of other fully defined reference points if that's also needed to close the profile.
Now how this may work in a collaborative effort is uncertain: one person doing does not remove entities being referenced, but rather makes new ones to complete the task at hand. In theory it sounds ok, but then another person finding duplicate entities could undo this tweak or workaround.
