Scott Barkman: Tips for Loading Large Models Faster




Whether you design luxury yachts or handheld medical devices, your assembly can include thousands of parts and sub-assemblies. Try to load all that data into your 3D CAD system, and you may spend hours waiting for every last fastener to make its way to your desktop. Scott Barkman, Portfolio Lead at PTC University, wants you to know that there’s a faster way.

This year at PTC Live Global in Nashville, Tennessee, Barkman will deliver two information-packed presentations, one for PTC Windchill users and another for those using PTC Creo. But if you’re using both solutions, Barkman has a tip for you right now—one that will stop you from waiting so long to retrieve your models.

“A large percentage of our users with both PTC Creo and PTC Windchill aren’t using the tools to get better performance from their large models.”

With PTC Creo and PTC Windchill together, you can create simplified representations of a model and then vault them as a separate assembly file—an external simplified rep—in PTC Windchill. Unlike standard simplified reps, these standalone files can be created without requiring you to load the entire product assembly. External simplified reps are searchable in PTC Windchill too.

Use external simplified reps to prevent the system from downloading parts that aren’t critical to your work. For example, you might load an external simplified rep to avoid retrieving a complicated internal electronics sub-assembly into your session if you only plan to place a new label on the exterior cabinet.

“If you use external simplified reps, instead of bringing down 1000 parts, you only have to bring down 20,” says Barkman. That speeds up the time it takes to retrieve a model, and improves performance when you try to manipulate the geometry.

Saving a simplified rep externally

 

External simplified reps aren’t new to PTC Creo, but Barkman says many people still aren’t familiar with the functionality. Others worry that creating and modifying the simplified model will create unwanted noise, such as notifications or unintended changes to the master model, in the PTC Windchill system. Recent updates to the software eliminate those concerns. In fact, Barkman urges anybody who tried external simplified reps in the past to revisit the feature in the newer releases of the software.

Registration for PTC Live Global, June 7-10 is now open. For more insights from Scott Barkman, attend his presentations at this year’s event in Nashville, Tennessee, where he’ll talk about PTC Creo simulation tools and design modularization with PTC Windchill.

And here’s one more tidbit from Barkman: Many of the sessions from PTC University at PTC Live Global are presented for the first time there. “It’s a great event for us to get out there and present information that may not be written in books somewhere. We often use PTC Live Global to test training topics and see if the audience is interested and receptive.”  As a user, that means if you don’t attend, the opportunity may not come up again!
