DXF-import non-native CREO extrude -- impossible to work with

cgherghe-2 — Fri, 29 Aug 2025 07:41:01 GMT

I have imported a DXF file in CREO and thus created an extrude out of this DXF file, using the PROJECT function.

To distinguish this from a regular CREO extrude, I will call this non-native CREO extrude a DXF-import extrude (for lack of a better name).

If it already has a name I will stand corrected.

Anyway, this DXF-import extrude is impossible to work with.

I am trying to make it accept a different color than the background, but it does not work with regular means -- this DXF-import extrude seems to be a surface that CREO cannot handle like any other extrude generated directly in CREO without an external import.

Is there a way to make this DXF-import extrude behave?

Maybe create another native CREO generated surface, identical with the DXF-import one and transparently on top of said DXF-import extrude, that would be more amenable to work with?

I have attached the PNG file (source for DXF), the DXF file, the part file with the DXF-import extrude and two screen shots of how it looks and how it should look.

Many thanks!

I typically import DXF in to a part and then use that to create creo sketches from. I don't ever extrude directly from the DXF.

Just a quick glance at your images and I have no idea if it will work for you.

The DXF import curves are definitely a different type. To color the imported curves, you should window select all of the curves and, from the RMB menu, select properties then change the color.

Coloring the extrude surfaces act normally for me.

How do you create the sketch from the DXF file?

Here are the steps I followed in order to produce that part...

PROCEDURE for DXF extrude in CREO:

01) prepare DXF file similar to a laser cutting file (all lines belong to closed loops)
02) create new CREO part, change accuracy to ABSOLUTE

03) select FRONT plane

04) Get Data --> IMPORT: select DXF file

05) accept default settings for import

06) click OK on ribbon

07) select again FRONT plane

08) click EXTRUDE on the ribbon

09) click PROJECT button (two windows pop-up)

10) keep the Selection Mini Toolbar, close the other window

11) create geometry from all the closed loops

12) when all loops have been traced, click OK on the extrude ribbon

13) type value for the extrude height/depth and click OK

14) save the CREO part.

How do you color the imported curves?
I do not understand how I should window select all of the curves and then select properties and change the color...

Hi,

I opened your model (ARMS_CROSSED.PRT) and I put a white background body behind the solid you created as per above, and the result is pretty close to what you are trying to accomplish (Screenshot_arms_crossed_03.jpg) - isn't it?

Please clarify what is the problem with the extrude.

Move curser to top left of screen.

Press and hold left mouse button

Move curser to bottom right of screen and release left mouse button. (may take a while for all of the lines to select)

Long press right mouse button

Select Properties from pop-up menu

Select the color button

Select a color

Select OK

Select Apply

Select Close
