Hello Michael,
thank you for your explanation, now it is clear.
Also thank you for polyhedron tips, I will try to use them to keep the model easier to manipulate. My experience is, using a lot of NURBS surfaces slows down the rendering and manipulating. I am doing a lot of Boolean operations and some of them will fail with non-planar surfaces, or result in losing the "solidness" and change to joined surfaces.
I also played with parameters at .stl export, and found better to use more polygons and let the printing software to "antialias" the surfaces.

Michael, you are doing a good job, I like MOI and thanks MOI I can build nice railroad models :-)

Hi jik, those are some great railroad models!

Yeah also using the "Divide larger than" parameter can be good for getting more evenly sized pieces. If you put in a distance in "Divide larger than", any polygon that's bigger than that size will get diced up further. It can help to avoid making triangles that span a large distance across the model. Something like around 1/20 of the overall size of the model can be good to put in for "Divide larger than".

did you increase your viewport mesh angle(initial would be 10)? you could also uncheck "Add details to inflections" and "Display hidden lines", which should definitely improve the overall handling.

Very nice! What are you using to print those?

Supagoat:
originally i have tried photopolymer, but the models are too light (0,5g)
now I use print to wax and lost-wax technology casting using brass.

photopolymer


wax prints





brass casts (the silver ones are from pakfong, just for testing)



coi:
to be honest, i didn't play with those settings, but will try, thanks for tip
