Constraint Problem- Suite 2009 SP1

Anonymous

Hey guys and gals...



I'm having a problem with Inventor Suite 2009 SP1, wherein, I have two holes on a hinge that are 1.8898" apart, and two Pem Studs on the mating door panel that are also exactly 1.8898" apart, vertically aligned, and fully constrained in the related sketch.



Now, when I place an Insert Constraint on the top hole on the inside of the panel, to the Hinge's corresponding top hole on the outside surface, it places the door panel on the hinge. No problem.



When I place either an Insert Constraint in the same fashion as above to the second hole, or a Mate Constraint to the axis of the shaft of the Pem Stud and to the second hole in the hinge, the constraints "blow up" and generate a list of conflicting constraints.



This should be a simple thing for Inventor to do.



What gives?



Thanks in Advance.

The holes do not line up exactly.

Did you model the hinge or was it translated in from step, iges etc?

I would change your precision when you measure to all
decimals, and make sure they are the same.

Ground the two PEMs. Delete the rest of the parts except the PEMs and the hinge. Zip and attach 2 ipt and the iam here.

How do you figure the holes don't line up exactly? There is no deviation from zero in 2 axes (Delta X, Delta Y) and I've measured the part to 4 decimal places, and the hole centers measure .205" from the right side edge of the hinge.

Then measure the translated part using all decimals.My guess is the translated part isn't correct out to the .xxxxxxxxxxxxxxxxxxxxx decimal
place which will cause it to fail.

That worked... Thanks bro. I must say though, I find it hilarious that you would need to carry the dimensions out to 9+ decimal places to get a constraint to work.

I don't even think a Machine Shop can hold that kind of precision, without charging you some astronomical amount for the part.

Post the step or the ipt, doesn't matter as far as finding the problem.

I assume the holes were off in the translated STEP file. Could it be a conversion between inches/mm problem?

You could use the Delete Face with Heal option to remove the holes and put them back in at exactly 1.8898".

There's your clue... Try the Delete Face with heal option and
remake the hole. 4 decimal places is nothing.

The solution to your problem is simple - SolidWorks

I recently had to change jobs -got laid off- and am forced to use Inventor. I've used it for quite a while now and, trust me, Inventor is no match for SolidWorks. I too have simple, stupid ace problems that I know SW would not give me. Inventor is still behind the times. I've even had people who have used it for YEARS that have switched to SW and tell me it is not as powerful as SW and Inventor is intended for the not-so-bright engineer (user).

My experience is 10+ years in tool and die, helicopters and CNC routers (all in the design/engineering field). I have used a handful of CAD programs and Inventor is by far the one in last place. I love how ya'll brag with your long signatures. What's next, "Rocket Scientist"?

Any way, cheers...thank God we don't need drafting tables any more...
