Issues while importing .stp files in Lemoine RTM

[ktool]

I am using Creo Parametric Release 7.0 and Datecode7.0.2.0

Our company use Lemoine RTM to machining blocks, currently we are using creo 7.0 to design and export stp files to shop floor.
it works fine when we load igs file in Lemoine RTM , but now we switch from igs file to stp file.
stp file contains solid block model with 3D surface on top. usually we created a layer named 999 to keep 3D surface
the solid block needs to be colored in grey(the only option we can do is select part and put grey color to ensure Lemoine shows grey), for stp file layer999 is disappeared in Lemoine RTM.
I tried to remove all color in creo proe and export as stp file, it works but not what we want. hope we can solve this issue with your help, appreciate all.

let me know if you need more detail about this issue,

What version of Step are you exporting out as? Have you tried changing the step version? If you click options next to save as step you can pick the version.

Some support colors others do not.

If the issue is that you have a local surface that is coincident with another surface then this isn't supported until Creo 9. Prior to Creo 9, Creo merges coincident surfaces together.

Hi, this is the stp file exporting setup.

We still using Creo 7.0.2.0 for design and I haven’t try creo 9 yet.

Problem we have now is a solid block have a 3d surface which in layer999 in part mode, but it shows all pink in Lemoine

If I try to fix the pink issue and put color grey using part selection to add color grey in creo 7.0.2.0

And this may cause Lemoine not able to read stp file properly.

I will try to download 9.0 at home to see if it works tonight before we update to creo 9.

Thanks for helping
