Material selection in step file?

Recommended Posts

Hello! 

I got a step file from my customer. When I import it, I get no materials - yet still there are some colors on the model in c4d. See the image.

Now there are 2 materials but those are made by me at cinema 4d. The imported step file had really no materials. Still there were different colors on different parts. How can I select for example all the blue polygons at the top? So when I have them selected, I could assign a new corona material on them all at once..

They are not materials per se. The objects have been assigned a display colour (see example attached).

Usually, one of the first steps (no pun intended) with stp files is to go through the hierarchy and put things in proper groups for easy selection later.

Unfortunately I don't think there is any process that will do this automatically, so you do have to select things in the VP to find them in the OM.

Actually, no I'm wrong; there is a quicker way to identify parts I'd forgotten about, though the grouping thing I originally mentioned still applies.

 

But when you merge the step file in there is an option to turn display colours into actual materials (Optional / Materials). If you do that, then you can use the normal material search functionality (see material manager menus) to find the objects based on their auto-generated materials.

 

However, from the looks of your file, and its really simple block form, it might still be quicker to just be in object mode using the rect select tool ! 🙂

In my experience sometimes the model pieces/parts are saved on different colored layers. If that is the case then there is a handy little script by Donovan that will merge the parts according to their layers which will save you a lot of time. Let me know if you are interested in his script.

Thank you for these solutions! I also found that when opening / merging a step file there is a option to create materials based on the display colors of step file.

This was the thing I was looking for. This is a great time saver for me!
