Exporting STEP file from 3dsmax?
show user profile  MrPumpernickel
Okay, before I go into the backstory, is it even possible?

I'm working on modeling a parkbench in 3d (quite organic design) that will be milled out from a huge block of oak. The machinist needs the model in STEP format (it needs to be a proper solid etc) but I see that 3dsmax doesn't have that in its export formats. Is it possible to export STEP from 3dsmax, maybe through an i/o plugin (haven't found any)?

I'm in a bit of a bind, if I can't solve this by monday the project (and quite a few tousand dollars) will be delayed and could possibly fall through completely.

Power Translator from nPowerSoftware ->
is the only one that comes to mind ( which might have that capability ), but it's commercial plugin and demo version export might have limits.

EDIT: Ok, checked the site... it has STEP export, but it works only on nurbs objects. I assume that your model is polygonal.

some of those models look like evermotion collections and this sort of thing isnt supported on these forums. consider this a warning

edit: unless they aint then ignore

like TimTam said, Step is a common export format in the CAD industry.. and it is only NURBS, so a MAX poly object wont work.

The guy who does the milling, ask if he supports .STL files, which is pure mesh, max supports those, and they are the normal format when doing RPT. As far as I can recall, though, CAM software works mostly in NURBS, but its worth a shot.

I know that there is software out there that can (attempt) to convert mesh to NURBS surfaces, I think there was a plugin for Rhino, but I cant remember the name(Google tells me theres quite a few, but I have no idea how well they work)

Depending on the size of the thing, and the deadline, maybe look into having it made with RPT instead, like SLS, SLA or Zcorp. That way you can use the mesh model..

/edit.. heh I did actually miss the whole "block of oak" bit...

Terribly boring signature.

Drat, it's what I feared then, I have to model the whole thing in Rhino. Not that I can't do it, but it'd be so much faster and easier to do it with poly modeling.

TiMoN, RPT? Yeah, I don't know about making a 4 meter wide, about 1 meter high and deep, model with RPT, and making it so it can stand the wind and weather for an entire summer. Heh. (maybe you missed the "parkbench" and "huge block of oak" part of my post :P)

Thanks guys!

Just an update, bench was modeled entirely in Rhino and Solidworks (nice to learn a bit of Solid as well) and sent off to the guy with the big CNC machine. Everything looked a-ok and the bench is being milled starting on monday. Should take about a week the guy said, which I guess is not bad for a 3 meter long parkbench :)

Looking forward on seeing what your artistic mind has cooked up.
