Hello,

My company would like use Three.js to make a configurator.

My only source file is native alias 3D file (.wire). I need your help to know how to convert my .wire file to something compatible on three.

my software : Alias Autodesk, blender

Thank you in advance :slight_smile:

Try to export your models to STL. Alias Autodesk should provide a respective export option. In the next step, load your files via STLLoader.

https://threejs.org/examples/webgl_loader_stl.html

There is no loader in order to load (proprietary) wire files directly into a three.js application. I also think it’s no good idea to develop something like this since CAD file formats are often very complicated and not polygon based.

Hi and thx Mugen !

I have only SAT, FBX, OBJ, DES, VDAFS, JAMAIS, VDAIS, IGES, STEP and WIRE export with Alias

I did not find yet the good process to export to threejs

With fbx export i have some material losses :s


#4

There are also loaders for OBJ.

e.g. https://threejs.org/examples/webgl_loader_obj_mtl.html


#5

No work, mtl option does not exist :s


#6

I’m a little bit surprised that you have no export option for STL. It’s more or less a standard file format of CAD tools…


#7

Someone uses alias? :s


#8

Why not just asking the Autodesk support/community? :wink:


#9

Or whomever is providing the wire file, you can ask them if they can provide something else.


#10

yea sure…


#11

they can not… only Fbx export but they dont know exactly how to do :s

I need a process :confused:


#12

With fbx export i have some material losses :s

Are you using the latest FBXLoader from the dev branch?

I need a process :confused:

Your process should be to get the files properly exported in either FBX or OBJ formats. The place to ask about that is the Autodesk forums.

My options is :
File Formats : FBX
Logfile Output : Yes or No
Export Curves : Yes or No
Export Symmetry : Yes or No
Export Instances : Yes or No
Export Variants : Yes or No
Export Cameras : Yes or No
Export Lights : Yes or No
Export Shaders : Yes or No
Divide Periodic : Yes or No
File Format : ASCII or binary
File Version : 2016, 2014, 2013, 2012, 2011, 2010, 2009, 2006
Axis Conversion : Z Up Axis or Y Up Axis
Trim Curve Type : 3D model space curves or 2D parameter space curves and 3D Curves or 2D-3D model Tessellate : Yes or no
if Yes Tolerance : 0.01 and Tesselator : Acurate or Fast

An advice ?

Thx


#14

Those are good options!


#15

You are going to have to test the options yourself to see what works for your model.
However, you can start with yes to everything, Y-up, Binary format, version 2016.
