I answer the easy questions if I think I know the answer.
About the only things I know are - "Sketch1 isn't constrained" and "an iam without ipt files is useless".
If you stay here a while you will see that I have copied those two responses here around 19,000 times.
then Please JDMather i want ur 19826 answer to my qustion ,(( A Cyclical Constraint dependency was detected)). WHY this error appear in my Inventor?
I also have a problem with my frame generator. I have a fully constrained sketch, which I could use yesterday for frame generator, but today, I haven't changed the sketch or anything, my frame generator does nothing.. It tells me to select the lines or sketches I want to use, but I can't do anything else..
You should have started a new thread for this as it sounds like your problem is different.
Have you installed all Service Packs for r2013?
(the answer is no)
Have you rebooted the computer and the problem persists?
In the assembly you attached the skeleton sketches visibility is turned off.
Also missing the frame files as unresolved (do you get this error or do you see your frame? - post screen shot).
Are you using Vault? Project?
I rebooted my pc, and it made no difference. I tried on a friends laptop though and it worked. Normally all the service packs are installed, it updates automatically. I'm working in a single user project.
The sketches are ok, no issues. Normally when I start frame generator from these sketches in an . iam, it gives me a box, where you can choose materials, size, placement and so on.. Now I can only select those sketchlines I want to use, but no more than that. I don't see no box, no command to follow up with.
I attached a screenshot from the . iam
No, iProperties indicate that at least with the file you attached your Inventor Service Packs are not up-to-date.
I have heard of Windows Updates occurring automatically, but I have never heard of that behavior with Inventor updates.
I even posted link above. (post screen shot of Help>About Autodesk Inventor showing that your SP are up-to-date)
Are you using dual monitors - I suspect that maybe the dialog box is off the screen.
But before doing anything else I would
1. Temporarily turn off UAC and Anti-virus
2. Install Service Packs and Updates for your release of Inventor
What version of Windows are you using?
