Mark Ganzer: Doctoring More than Imported Data




When you’re working on a design in PTC Creo, you can save a lot of time by importing supplier parts into your overall assembly. The good news is that vendors generally provide their products in neutral file formats, like STEP, so you can just drop models into your assembly as needed. The bad news? The results often need more than just a little manual repair.

This year at PTC Live Global, June 7-10 in Nashville, Tennessee, long-time user Mark Ganzer talks about how to make those imported files work more effectively in his presentation, “Import Data Doctor for the Rest of Us.”

Gaps, failed solids, lost visualizations—many people just live with the problems. Others recreate the model from scratch. But Ganzer says that you can use PTC Creo’s Import Data Doctor (IDD) module to quickly fix problems introduced with those neutral files. And best of all, you don’t have to be a power user to do it.

With the IDD toolset, you can fix gaps and sliver surfaces, fix tangencies, modify curves and surfaces, and so on. “Import Data Doctor has a lot of features, but you only need to learn a few things to make it work effectively. You don’t have to be an expert,” says Ganzer.

Doctoring More than Imported DataHere’s a tip from Ganzer that even seasoned PTC Creo users may not know: Import Data Doctor can work on your geometry combined with the imported files, too.

 “When you import a model, it shows up in the model tree as Import Feature,” says Ganzer. “And typically, you apply IDD to that one item in the tree.”

The problem is, Import Data Doctor doesn’t always have the tools you need to create the surfaces and features you want to patch that imported file. In that case, you can create those surfaces and features yourself.

“The trick is to then use Collapse Geometry to combine everything into one environment where you can use the Import Data Doctor tools,” says Ganzer.

For example, you can use IDD’s repair tools to close up a gap between a surface you created and the imported model.

To collapse your geometry, just select it along with the imported geometry in the model tree (CTRL+left mouse). Then click Model > Editing and then click the collapse button:
