hole to hole constraint

[lfoley2]

The axes wont align when I attempt to mate the holes on two seperate parts in the assembly. anybody know what my problem is here?

[andrewiv]

When you try to apply the constraint, does it complete or does it give you an error?  My guess would be that either the preview isn't working correctly or there is another constraint that conflicts with this one.

Can you post the ipt and iam file? 

You should be able to just measure and see where the difference in its positioning lies with respect to each other.

From your picture, the holes on your two parts, one of which is perpendicular to the rotation axis, and the other is perpendicular to the inclined plane?

[lfoley2]

It gives an error

[andrewiv · Accepted solution]

If the part is free to rotate then I suspect that both holes are not perpendicular to the center axis as @chenj mentioned.  If it is not free to rotate then there is another constraint that is holding the part at an angle.

If the holes are not perpendicular to the center axis and this is what you want, then you will have to create a work point on one of the parts and mate the axis of the other hole to this work point.

If you attach the parts and assembly then we could probably get to the bottom of this quicker.  Also, what version of Inventor are you running?

[lfoley2]

Yes the related files are below

[lfoley2]

yes okay i will have  a look at it and i attached the files below

[lfoley2]

The version is Inventor 2020

Hole4 in Marafind housing part 2.ipt is not axially oriented to the part, because its sketch is located on Work Plane 8, which is tangential to the face, but not at the hole location.  If you want the hole centered under the square opening, then you will have to redefine Work Plane 8 to be tangential at that location.

I'll attach a different method to make that hole in a few minutes.

I just redefined the constraint with an insert (which can also be locked to avoid rotation if you'd like):

Here's my edited version (2020 format) that just deals with the hole alignment issue.  There are a number of other issues that need to be addressed, too, starting with Sketch1.  Also, the same hole alignment problem occurs in the mating part, so fixing it in this part is only fixing half the problem.

Seems as if you could use some training-- would you like for someone here to coach you through creating these two parts using better modeling practices?
