Recovery of 3D surface on catia from stl file

3D Design Volume Model

Hello

 

I want to recover a very detailed 3D bas-relief, in stl format, with catia. I use quick surface reconstruction and then automatic surface but the result is very approximate and I can't keep the details of the bas-relief. Do you have a solution to remedy this? Another CATIA tool or a parameter optimization? (I have already modified the parameters many times without interesting results).

 

Thank you

 

Matthew

Hello.

HA1 (healing assistant can help you correct surfaces)

If your Stl comes from a point cloud (and you have it!) DSE to prepare the mesh.

After all, whenever possible, it's better to redesign rather than use the result of an stl.

I can't help you anymore I don't have these modules available.

Kind regards

Hello

Stl is the format used for stereolithography

http://fr.wikipedia.org/wiki/Fichier_de_st%C3%A9r%C3%A9olithographie.

Try to work with other formats such as iges for surface and surface or volume step

Hello

 

if you post your .stl file

I can look to transform it.

Hello Mathieu,

 

.stl is clean in terms of structure and errors, manifolds, etc.

 

on the other hand it's all ch'ti ^^

 

do you have weird gaps??

 

So I cut the area and I get to a file:

 

183,230 stitches => 364,728 triangles

 

0.841 x 0.998 x0.05

 

I have started a reconstruction I am waiting to have a result and I will see you again

Hello

I'm going to play the spoilsport but I don't think the result is usable (300 Mega) for 1mm2.

Matt you must have a scale PB on your stl.

What's the goal!! because this kind of surface is expensive to machine.

Hello again,

 

When importing a .stl into CATIA, you have the choice of scale and I chose 1.

 

The scale is fixed by the capture system.

 

then we realize that there are defects on the scan result

 

while I have already  cut in order to limit the defects as much as possible

 

The size is related to the accuracy of the scan I am at + 99%

 

For me it will be necessary to recross the surface once the best conservation zone has been defined.
