Cannot place constrain in Inventor

[ChrisH]

The mounting holes for the Van Door are 1/4" dia on a 1.5" radius. They are 120 degrees apart. I typically have trouble getting it to line up properly. So here's how I handle it.

First use an INSERT constraint on one of the mounting holes on the motor. I usually use the one that sticks out at 90 degrees to the motor axis.

Then I use an angle constraint between the edge of the mounting plate and the web supporting the mounting hole. Adjust the angle as needed to get the holes to match.

The speculation that the problem is not getting the numbers to match is probably correct, but we don't have the ability to specify the numbers to the tolerance needed to eliminate the issue.

so basically you are trying to place 3 holes on 3 pegs?

The way by creating a component off of the motor sounds like a good idea. Haven't tried it yet but I will. Thanks.

Paul,

The reason it is a good idea is because once you have an existing stock component, like a motor - and hopefully an accurate model - you do not need to analyze the component to create a new sketch for a mounting plate. You just project the geometry and let Inventor do the work. It is a much more productive and intuitive method in my opinion. And you won't get that "Can't create a constraint..." thing anymore. Believe me, I have been there. It drove me crazy. If you need more help, just yell!
