Can't repair the model with IDD

vincecatlin — Fri, 06 Mar 2026 17:44:08 GMT

I have an imported STEP with what looks like a small number of errors: 10 bad two-sided edges and one bad wireframe and, wow, 75 bad vertices.

There's one particular inside radius that seems to defy any attempt to fix.

I just opened your posted STEP file in Creo 10.0.9.0 and the model imports into Creo as a solid body. There are geom checks but IDD interaction is not needed in my case to get the geometry to solidify.

Describe exactly the steps you execute when getting the STEP file into Creo and what version you are using.

The most common solution to import errors is letting the imported part drive the accuracy!

This is great news. Unfortunately, this is not what I get.

This is with Creo Parametric 10.0.7.0

Hey, maybe you could include the nice Creo native model since nothing I do seems to work. You don't suppose our "templates" (start parts) might be causing the problem?

Open the STEP file directly in Creo (do not use a start part) and report back the results. Your start parts could very well be the issue, this is why I inquired exactly how you were bringing the STEP data in.

Use file open without a template as shown below.

Success! This turned out to be a simple solution. I had tried with the template unchecked but this time I also selected "reset"
