I don't have any problems with that sort of stuff on my PC. Is the LO project one you started on the PC? How big is it?

In LO select your model in the paper space. In 'model dialog/styles/line weight'. choose line weight.

@adrw2001 said: I'm having a sporadic issue that is quite disruptive to the Layout workflow... any help is greatly appreciated! Occasionally, I can't control the front/back order of elements, especially lines/dimensions drawn over the model. I can select the line and say 'bring to front', I can select the model/drawing and say 'send to back', but no matter what, the line/dimension will stay hidden behind the model... suggestions?! thanks! Be sure to check your layers... layers at the top of the list appear above layers at the bottom.

I've noticed this also. It happens infrequently. Sometimes I can't dimension in the scale of the model, but it measures the paper space, as you put it. It hasn't happened enough to notice if anything particular trips it, but I wonder if it's associated with changing scale. Bst, Jim

Have you ever tried to uninstall and clean all files dedicated to SU and reinstall? Also if you are not using the latest version, maybe updating helps. If you can not fix it, go on windows version.

and if all that doesn't help, you may be in the "wireframe" face style mode. then you just have to change to one of the other modes (shaded for example) and you will see all the faces again. this sounds far too simple. but it happens quite often...
