Hello.
I did not find any information online, so that’s why I open this topic now.
When I try to export a lasertag (lines/curves) in a step-file so that our manufacturing partner will be able to engrave that text on tubes.
But it is not included in the export. I am not able to find any option to include curves, but I know that my colleauges are able to in inventor and creo.
I also tried to create a block including the cures, so that it’s recognized in some way.
Hi Helvetosaur.
I can. What you might need to consider and clearly I forgot to mention is:
Once I reopen that step in Rhino again I can see the lines.
If my colleauges open that in Inventor they cannot.
So the Question is: is there any setting that will do the job?

Ah, OK, so the curves are there, but Inventor is not able to read them… And you say that Inventor is able to read step files with curves coming from other software? I’m not sure I can help with that then - don’t know what Inventor might need in that case…
According to my knowledge, the Inventor or Solidworks have problems with imported 2D geometry coming at least from Catia or Rhino, becuase I tried to repair the curves coming from Catia in Rhino and import them to Inventor or Solidworks.
I tried to import 2D curves in three different formats - catpart (original file), step and iges into the mentioned CAD programs and the results were strange - e.g. the curves were not visible or were broken, points on lines didn’t lie on the curves…
Hi.
We did try iges now, inventor has no issues with that, but now the manufacturer has issues.
They are using “ARTube”. I also tried to read a file they created for us and we could not see their lines.
So, Nosorozec… no chance then?
Is there a way to really “engrave” a line (=extrusion of that line) in a brep?
I am sure that is not working as well, as it’s not brep, but only surface then and that will not be engraved.
Do you have a STEP file with curves that do show up in Inventor? If so, either post it here or send it directly to me, chuck@mcneel.com. There are many ways to put curves into a STEP file. We have to find one that Inventor likes.
Thanks. I don’t see anything obvious. The two files look pretty much the same. Both have the curves in a geometric_curve_set entity which is referred to by a geometrically_bounded_wireframe_shape_representation. I thought maybe the files would be different in that respect. I’ll dig deeper shortly.
None of the files was read with lines by Inventor.
None of the files was read with lines by ARTube.
An igs-Version of both files was read wiht lines by Inventor.
An igs-Version of both files was NOT read with lines in ARTube.
Both step-files were successfully read with lines in Rhino again.
Thanks for the clarification. What I’ll need is a step file from anywhere that contains curves which show up when read into Inventor. A good source would be if you could read the Igs file into Inventor and write the result out as step. I don’t have access to inventor.
Hi Chuck.
This is the file I was able to read in Inventor.
The tube consists of two parts, which is okay (if you might ask yourself why that modelling is so poor. )
