Cutting existing part in Creo

mbugler — Wed, 12 Dec 2018 15:40:17 GMT

We are using Creo to CAD our FRC robot. We downloaded FIRST parts, the only thing we need to do it cut down the preexisting parts. How can we cut down a part in PTC Creo that we downloaded from FIRST?

You have several options.

1) Assembly cuts; remove material from an assembled part within the assembly.

2) Add to the model; you can operate on the import solid within the part file as you normally would.

3) IDD; Import Data Doctor can modify the import file directly including fixing bad imports.

Thank you for responding! For example, we are using AndyMark channel for the frame but the length of the channel is wrong since we cut the channel down for the robot, how can we cut a piece such as a channel shorter in CAD.

I would suggest saving it as a copy adding the length to the original name. You can then open the copy and make an extrusion cut to make it shorter.

4) Flexible assemblies; you can change the value of a fixed length of a native feature at the assembly level.

Are these fully parametric models or imports? I have never looked that the FRC kits.

Most of the parts we download from AndyMark as STEP files

Consider re-modeling them from scratch. You will learn a great deal and will find it easy to do after you get used to it. And much more powerful than trying to work with a STEP file.

You could remodel them if you have the time and want to get better at CREO. However, with COTS parts, using the STEP files, from the manufacturer, and cutting away material is the easiest and most accurate way to create what you need.
