Tips & Tricks: Working with Chamfer-like Geometry in Creo FMX




In the past, whenever you moved geometry adjacent to chamfer-like geometry in Creo Parametric, the chamfer-like geometry would extend and intersect the moved geometry (see figure below).

Now with Creo 3.0, the system automatically handles chamfer geometry created with Creo Parametric 3.0 or later as a chamfer, meaning that the dimensions of the chamfer remain constant even while adjacent geometry moves.

Of course, most geometry wasn’t created in Creo Parametric 3.0. So what do you do with imported data or older geometry?

With a few simple steps with the Creo Flexible Modeling Extension (FMX), you can make the system recognize chamfer-like geometry and edit it as if it were a chamfer. Here’s how:

To make the system to handle chamfer-like geometry as a chamfer, follow these steps:

  1. In the Flexible Modeling tab, click Rounds/Chamfers > Recognize Chamfers.
  2. Select your References, and click OK.

Using the Move feature, you can now see the system maintains the engineering intent of the chamfer. The system does this by first removing the chamfer, executing the flexible modeling operation, and then recreating the chamfer.

Chamfer and chamfer-like geometry can be edited with the Edit Chamfer tool. Similar to rounds, you can remove the chamfer or change its size and dimension scheme.

To edit a chamfer and chamfer-like geometry, follow these steps:

  1. In the Flexible Modeling tab, click on  EditChamfer.
  2. Select the Remove Chamfer checkbox or change the dimensions scheme or values associated with the chamfer as needed (see image below).

Finally, to edit chamfers in a pattern, you only need to change one pattern member. Just make the change, and then quickly propagate the changes to other pattern members.

To edit chamfers in a pattern, follow these steps:

  1. In the Flexible Modeling tab, click EditChamfer.
  2. Click the Options.
  3. Click the dialogue box below Pattern/Symmetry/Mirror feature.
  4. Select a Pattern or Pattern Recognition feature within the Model Tree. The system will propagate the chamfer edits to the other members of the pattern.
