Hi all,
I design boats in rhino and build them as well. They are cnc cut and welded. To make this easier, it would be good to add some lines on the drawings, to indicate where parts should be welded etc.
In SolidWorks this is done by cutting a very thin and shallow line. If i do this in rhino, the closed polysurfsce becomes open, and the cnc software doesnt accept it anymore.
What should i do?
Many thabks in advance!!

Hi Huib - I guess you mean that SW adds a shallow groove to the plate, is that correct? Can you post an example of what you have and what you’d like to have?
-Pascal
You are wanting to put a groove in the metal , so a person knows where to put the welds , I Am guessing. SW has thickness in its parts, correct?-Mark
If this is the case. Could you put small darts on the edges of the cut piece where the welds would go?
Hi Pascal, that s correct.
When i draw a shallow groove, the cnc will only scribe the line. Instead of making a cut.
But how do i draw shallow grooves like that, without opening my closed polysurface?
Thank you!
Hi Huib - I might be able to cook something up that could work… not sure - can you please post or send me some examples of the input and the desired output? Including grooves from closed curves, if that is something you need.
Something like this -
-Pascal
Have you tried pulling the line to the surface (if not already on it), solid piping the line with a small radius (less than the polysurface thickness) and, then boolean differencing the pipe from the polysurface?
Yeah… @hdmaritime - if a semi-circular groove is all you need, then a pipe should do it as Jeremy says - if it is a V-shape, then it gets more involved…
-Pascal
Could the shouting lines option being enanched by adding the welding shape as well?
Hi Jeremy,
This seems to work! The software has accepted it, will test shortly it the machine accepts it as well…
Thanks!
