Does this make sense to all y'all max users?
show user profile  9krausec
Long story short, a company we deal with is charging way to much and their justification is below in a list format as to the steps they take to process some of our work. Now.. Most of it makes sense, but step 3 and 4 throw a red flag. Why the f*ck would you Convert nurbs to a mesh then export as a step to import into 3ds? Are these people smoking crack or am I just confused?

"1 - Opens solidworks assembly file with all the respective parts files in Rhino.

2 - Remove all the parts that are invisible.

3 - Convert all the NURBS surface model to Meshes

4 - Export to "Step" format

5 - Importing step file to 3Dstudiomax software and set the unit to meters

6 - Optimize all mesh in order to obtain a maximum of 30,000 polygons per model (sometimes some meshes are destroyed at optimization, you need to rebuild some parts from scratch to get all the parts fine and not jagged)

7 - All parts shall be assigned material color, and only standard materials that we can receive and nothing else. It's just diffuse color that we use with the basic parameters and no reflection, bump or other mapping functions, except opacity when you use a PNG texture.

8 - All parts of the frame to be made into a single mesh and is called "Frame", also the same applies to "Upholstery"

9 - We need to process the images on the logo, placards, etc. to be applied to the model. Only JPG and PNG formats that we can receive. All the textures / images to be used on the models must have the highest hand one 64, 128, 512, 640 and maximum of 1.024 pixels. All the names of textures must begin with MAG_ ...

10 - Apply the textures of the model and assigned UVW mapping"

No, that makes fuck all sense (and I don't know what "Step" format is).

But the real kicker for me is step 9. "Only jpg and png... and maximum of 1,024 pixels." What decade are they in?

Just guessing here, could be wrong, but it sounds like they don't have SolidWorks, so they use Rhino to import the SolidWorks files, and then they export them to a format they can open in 3ds Max.

If you're the one giving them the files, just export them out a .step, iges, or some other format 3ds max can open. Step would be better, it would come in as a body object.

If they have SolidWorks 2005 or later, then 3ds max can import the native SolidWorks file, at least in 2014+, not sure about earlier. (link)

seems there has been a lack of communication about exactly what you two companies needed from each other
time to renegotiate contracts perhaps because the amount of extra work they're having to put in to make the product to their spec isn't allot but could damage your reputation in the long-run

oh, there is. I'm new on the scene, so I plan on clearing that up, but for what they are charging for what they are doing and then seeing that they are exporting a Mesh as a step file from Rhino (and not an OBJ) just threw me for a loop.

It's a longer story, but the base gist of this is that they are a service and our files have not been processed correctly (apparently) to implement into their system. Will be changing this soon, but like I said, Step from rhino to import into 3ds? Somethings not right there.

Rhino's NURBS export options are not terribly good, and neither are Max's NURBS import options. It can be done, but at what cost? They will ultimately become polygons at render time anyway so time-wise is it worth fighting? Anytime I've tried to export NURBS from Rhino (typically with IGES) I've ended up with a maze of normal issues, missing parts, and general build errors. Much simple to convert to an intermediate format like STEP.

STEP format is a widely used interchange format. It's one of the few 3d data formats I know of that actually has an ISO standard, which is why you see it pretty often especially where high density poly models are going to be created from NURBS. This makes sense as an intermediate format regardless of the ultimate use. OBJ can be... picky. If your input geometry isn't perfect it will tend to cough up some extra verts or flip a normal here and there. Better safe than sorry, basically. There's nothing special about either format but in my experience STEP tends to transfer to anywhere from anywhere without issue .In other words... no, there is nothing wrong here.

It sounds to me like you're providing CAD files and they're converting them for rendering, is this correct? If that's the case I'll do the job for 20% less. ;)

Sorry if this doesn't relate as I was given IGS (IGES?) files, but my recent experience (having not done it for years) of using cad was as follows

After a bit of time of fiddling to remember how to do the basic things, I could import the iges files into rhino, flip and merge them and export out meshes as objs perfectly fine, as dense as I wanted them

It was simple. Unless thats a great deal different to a 'solid works assembly file' (I doubt it as you can open it in rhino) then I would say its a simple process (at least for someone like me)

Rhino can import SLDPRT and SLDASM, but I have run into the issue of having multiple copies of one part or another. That's primarily on the modeler though. The cleaner the work, the cleaner the mesh.

Obviously. lol

Rhino's really good at importing NURBS from practically anything. There's a reason it's used so often as a go-between.

Mack_Blariah ftw. That is what I was looking for. I wanted to make sure I understood why STEP over OBJ and you just explained that. Thanks!
