Importing CAD file into matlab (STEP file)- Aircraft structure

Hello all,

I would like to import a cut out part of the aircraft shell and overlay with some existing/measured point cloud.

I tried to first import the ideal STEP file of the shell using the following code:

figure
Geometry = 'Shell single body'
gm = fegeometry("Shell single body.stp");
pdegplot(gm,FaceLabels="on",FaceAlpha=0.3)

But i was able to import only a very very small part of the shell within the cut out part .Tried to change the export types in CATIA and make fucntion changes but nothing works and i suppose that it runs and breaks as the meory is full (RAM) while reading such large file (2000KB), is there a way i can import such large Step files without loosing the geometry and would be able to overlay the meaured point clouds on it ?

Hey Dhinu,

Do you face any explicit error that you are running out of memory? Also coud you share the file or a dummy one of similar size and complexity to reproduce it

2000KB is only 2 GB. I would not expect that to be a problem except on systems that barely meet the minimums for running MATLAB.

There isn't any error mentioning the running out of memory , but the error looks like this .

I tried to upload the Dummy Step file here but the upload datatypes does not allow.

@Dhinu

zip the .step file and attach the .zip
