IGES Toolbox

Extracts the parameter data in an IGES file to Matlab.

Description

Toolbox for working with IGES CAD-objects in Matlab. The Matlab function ‘iges2matlab’ extracts the parameter data in an IGES file to Matlab. Other functions in the toolbox do plots, transformations, projections etc.

All user must first compile the source code. This is done in Matlab by running:

makeIGESmex

and the mex functions are compiled.

• MATLAB release: MATLAB 7.8 (R2009a)
• Other requirements: Some C compiler must be installed.

thans...i am new in this aspect and donot know how use it now

Is anyone else getting an error when trying to open an iges file?

Undefined function 'nrbevalIGES' for input arguments of type 'struct'.

Error in iges2matlab (line 628)
p =

Great code! Thanks!

[Yongxing]

very good

[NTUT]

when i run('C:\Program Files\MATLAB\R2007b\toolbox\IGES\makeIGESmex.m')

Could not find the compiler "cl" on the DOS path.
Use mex -setup to configure your environment properly.

how to solve this problem

[Luis Acevedo]

It is working now. I had a corrupt file in my comp . Good toolbox :-)

[Luis Acevedo]

Which type of compiler do i need?
C what? send me link

I have got the same problem than LuisCarlos, Liu and so on with a 64bits machine. fatal error LNK1104: 'nrbevalIGES.mexw64

Would be nice an update soon!

[Aleksandar Petrov]

:) I can use it, it works great!!

thank you

[LuisCarlosAbsalon RojasTorres]

Hi everybody! Please somebody can help me? when execute makeIGESmex i read this
LINK : fatal error LNK1104: no se puede abrir el archivo 'nrbevalIGES.mexw64'
I run it on 64bits corei7 and I cant use IGEStoolbox.

I am using these code. It is very good.

Now, We are waiting for Mr. Per to Add a new function "getpointfromIGES".
Hope we can get update soon.

Thanks!

Trying to import some IGES files but i get the following warning: Warning: There are unknown entity types for iges2matlab file.

Use "I-DEAS 3D IGES Translator" with NURBS as surface representation instead.
If you dont have that posibility you can add IGES entities into iges2matlab().
The IGES manual is found at

IGES files are not shown properly. How to add IGES entities into iges2matlab()

[Oscar]

Can somebody told me, how to do the opposite. I have a 3D figure generated in Matlab, but I need the figure in IGES or another CAD extension.

Hi, all

I am using NURBS Toolbox and IGES reader for MATLAB. The IGES reader is supposed to read IGES files from CAD softwares and extract geometric info from it. When i try to extract entities 126 and 128 (which correspond to NURBS Curves and surface). I am getting inconsistent results.

for example.

when extracting NURBS from a Cylinder IGS file from solidworks, I am getting no surface at all. When i use Rhino 3D i get a nurbs surface which looks like a cylinder but it's not Circular in shape like the IGES file.

I need to extract a proper NURBS surface that looks exactly like the IGS file

[Snahungshu]

Is it 2D plot only??

[Ernest West]

I have the same question above. I just want to be able to obtain the data points of a simple rectangle from IGES to matlab

[Bryn littlefair]

Can you provide a little more infomation on the application of retSrfCrvPnt. I am trying to extract an array of data for a surface i have imported. Many thanks

[By ?]

Thank you,this is a great job

fantastic job!!! thank you very much

[alloucherie franck]

good

[Kava Crosson]

Needs better documentation about projection parameters. Otherwise very impressive.

[bruce bi]

This is what I need. Thank You!

[Petr Volegov]

Need bspeval.dll for Windows x64. Could you please submit the source files too?

[Paolo Bertolo]

Fantastic job!
I've just opened a CATIA CAD file, converted into IGES using Hypermesh and then loaded it into Matlab. That's great!
