Summary | 0030024: Data Exchange - STEP, IGES export support of BRep shapes based on tessellated geometry | ||||||||||||
Description | occt7.3.0 now support tessellated geometry shape visualization, such as: readstl s test.stl triangulation vdisplay s But when save the tessellated shape to STEP or IGES, such as: stepwrite 0 s test.step The saved STEP file have no geometry data. | ||||||||||||

I upload the Recommended Practices for 3D Tessellated Geometry for STEP, the document can be downloaded from here: https://www.cax-if.org/documents/rec_prac_3dtess_geo_v1.pdf [^] |

Hello gka, I do not have an urgent need for this functionality. For the BRep shapes based on tessellated geometry, there are now serveral modeling alogirhtms support them, and can be displayed by the visualization module. For data exchange module, it supports the BREP, STL tessellated shapes. Implementation other file format to exchange tessellated shapes data I think it is important functionality. Best Regards, |
