Retrieve Dimension precision in IDW

[brownn]

I've recently been playing with the "Retrieve Dimension" feature in IDWs to pull the model dimensions and tolerances from the IPT.  I'm wondering if I am understanding the behavior correctly.

The IPT Document Settings > Default Tolerance "Use" and "Export" standard tolerance values boxes are checked.

I have standard tolerances defined for .xx and .xxx precisions.  Default in the IPT is .xxx.

If I place a sketch dimension and extrude a feature, place that part in an IDW, and "Retrieve Dimension," the result is that the dimension's precision and tolerance are defined by the active IDW style.

However, if I place the sketch dimension, and then modify its precision to be something other than the IPT default, when I "Retrieve Dimension" in the IDW, it pulls the modified precision and tolerance from the IPT settings.

Is this the expected behavior?  When I see the box in the IPT Default Tolerance tab that says "Export Standard Tolerance Values," I understand that to mean that the standard tolerance values in the IPT will be propagated to the IDW.  Is this incorrect?

EDIT: I'm using Inventor Pro 2013

Thanks,

Nate

Hello Nate,

Setting in IPT Document Settings > Default Tolerance "Export Standard Tolerance Values" is not intended to export tolerance to IDW but to iProperties of the part. When this setting is on then in iProperties of the document there is custom property PartAngTol*/PartLinTol* created for every default tolerance defined.

It is legacy as designed behavior that default tolerance defined in “Document Settings > Default Tolerance“ is not propagated to IDW when retrieving dimensions to IDW. If you wish some change in current behavior please log a request to IdeaStation.

Thank you for your input

Stanislav,

Thanks for your reply.  I will leave the "Export Standard Tolerance Values" setting alone, then, since it does not do what I thought it did.

Thanks!
