Tips & Tricks: Advanced Sectioning in Creo View MCAD




Creo View MCAD is a viewing app for anyone on the product team that wants to review, interrogate, mark up, and validate models—all without requiring a full-blown seat of CAD software. It doesn’t require any special design or engineering skills, so it’s perfect if you’re not already a CAD expert (say management, purchasing, tooling, and manufacturing) and want to provide feedback on a model. Here’s a quick overview, if you’re not yet familiar with it.

But let’s assume that you already have the app (the following features work with Creo View MCAD and Creo View Lite), and dive into a couple of interesting advanced features, specifically, sectioning.

Sectioning is an important tool in Creo View MCAD because it allows you to view internal components of the model without altering any geometry. You don’t have to explore the software long to figure out that you can activate a 2-dimensional plane (in the Sectioning tab, click View Section > Planar, then click on the plane boundary) and drag it through the model as desired to create a section view. Keep reading for a few more useful sectioning tricks.

Cap Sectioned Components

Notice in the section view above that the cut away parts all look hollow? You can make them appear solid if needed as follows. In the Sectioning tab, click Cap Section.

Parts in the cross section now appear solid with cut-away geometry capped.

Create a Quarter Cut Section

For a narrower internal view, you can drag two planes through an assembly. In the Sectioning tab again, click View Section > Quarter cut. Then drag each plane boundary as desired.

Section Parts

Suppose you wanted to drag a sectioning plane (or planes) through just certain components of your assembly, leaving others whole. For example, you may want to cut away a housing to reveal whole components within. You can specify which components are sectioned from the Intersection group. Clear the Intersect with all checkbox, click on the geometry you want to cross section, and click Add Selected.

Clearing the Intersect with all checkbox in the Intersection group allows you section only select components.

Now drag the planes through the assembly again, and you’ll see only the selected components responding to the sectioning plane.

Sectioning only select components (in this case, the motor housing) to reveal whole components inside.

See Sectioning in Action

Take a peek at these tools in action by viewing the PTC University Learning Exchange tutorial (don’t worry if you don’t have the sample model—cross-sectioning works with any 3D assembly).

The video includes additional tips for placing your section plane according to references you select. It also shows you how to flip geometry around the cutting plane and more.

If you’d like to see more, I’d recommend a visit to PTC University Learning Exchange for the companion tutorials, An Introduction to Viewing 3D Models in Creo View and An Introduction to Sectioning. You’ll need to create an account—but it’s free and there are 700 more tutorials just like this one waiting to show you how to use PTC products effectively.
