this has happened before and the cause was that we had envelopes in use. I have looked and can not find any envelopes in this assembly. The front end and a couple of other sub-assemblies insist on showing as dashed lines in the drawing. I have tried everything I can think of but can not get them to show solid for longer than 60 seconds. I have gone to the tree, selected the subs and changed the component line font to solid for all lines, the lines look good when the model regenerates, and then in about 60 seconds, poof, back to dashed. I have selected Show Envelopes in view properties, no change. I have set all views to high quality, no change. I have looked at the system options and can't find anything there either.
I have to add that this is a bad model somewhere and it lags terribly for anything I attempt to do with it. I thought it was because of errors so i have gone through each sub and cleaned up all errors i can find, but there is something that someone before me did that definitely isn't to Hoyle because it is very slow. Someday given time I will have to rebuild it from the ground up but not today.
At this point the only thing I have found that works is to select each line and set the individual display to solid.
Does anyone have any ideas?
I should add that this model has quite a bit of information in it so I probably shouldn't share it.
