Have you tried;
Running a repair?
Resetting the registry?
A non-modified Drafting Standard?
Copying the settings from anothe rmachine which does not exhibit this problem?
A clean re-install?
Which are all valid ways to get to fix the issue.
Still leaves the questions of why would it or could it do that on that particular drawing and not when I make a new one with the same template from the same 3d model on the same computer?
What I really would like is why it does it in the first place?
Because I'm getting rather fed up with having to redo,restore, re-start, reboot, reset (registry), re-install (every 2 months or so)
while the only thing that I'm trying to do is make piping drawings.
Why not use the "SolidWorks RX"
Tony, the short answer : Because Rx seldom works
The long answer :
Do keep in mind that SW did work normally in the drawings before, it does work normally in the drawings since then and there was nothing changed to the setup, nothing that could have influenced the registry nor the SW settings before,during nor after the making of that drawing.
Btw, I fixed that drawing by changing the type of arrowhead in one dimension and then use format painter to set them all similiar.
If you mean to use Rx to report the problem then you know as well as I do that it takes more time to report the problem then it takes to fix it and that the chances that one get an answer within a reasonable time frame is not likely.
Besides, that is if Rx works as it should, which happens more not then it does.
Reinstalling once again just because Rx is on the blink, again, no thank you.
BTW, Rx hardly ever works for my 2 collegues that also use SW.
Since september of last year I have installed SW'09, update when SP's came out, uninstalled it, cleaned up the pc, installed SW 10, formatted the harddrive, installed SW 10, always installing the SP's, reset the registry, had an audit by my VAR, soon will be installing SW 10 once more but this time on a brand new bigger quicker workstation (64) which sole purpose will be to run SW 10 and I hope, but am doubtful, that there will be an improvement in stability.
All I want is to draw. All I get paid for is to make piping drawings.
When I want to fiddle with computers then I do that in my spare time because I want to not because I have to.
Does Rx always work as advertised for you ?
Right-click a dot of an arrow and choose another arrow style. Does this help?
