MOI3d newbie - to create 3d products for carving on a cnc router table - can I scale down the file complexity

I am in the process, I hope, of moving into 3d carving.

I am ignorant of all things 3d, I am currently learning the new version of MOI3d that I just purchased.

Is your product useful for cutting down the complexity and therefore the processing time to do 3d carving on a cnc router?

I have been looking at the export filters in MOI3D and they either allow more or less polygons (?) to be created or in other file types you can select either "n-gons" or "quads and triangles" or "triangles only".

I have taken a .3dm file into a trial version of Vectric's Cut3D using the more or less polygons (,stl) and found that the more gives more detail but at a crazy cutting time of almost 2 hours for a fairly simple object.

Any information or appropriate links that you can provide would be much appreciated.

Hi Gary,

Thanks for your question.

In general, the best way to create a model for 3d carving is to export it with high resolution (more polygons) from MOI. So you will have all the fine details. Then, to speed up processing time of a carving software (like Vectric's Cut3D), it is better to adaptively simplify it preserving all the details you need and removing/modifying only redundant triangles.

You can try this with MOI, exporting to OBJ format. Then simplify your resulting OBJ model with Atangeo Balancer. Vectric's Cut3D also supports OBJ format, so you can load the resulting simplified model to Vectric's Cut3D.

We are currently working on an advanced version of Balancer that specifically targets 3d carving and printing. It will have error based simplification, so you will be able to simplify your 3d models exactly down to the accuracy of the carving machine (say 0.5mm).

Best regards

Thanks a lot.

I look forward to your advanced version. In the meantime I'm going to try and figure out what all the rest of the stuff means. Who thought that 3d would be so difficult to understand!
