| Summary | 0033638: Data Exchange, Step Import - Style for tessellated object missed | ||||
| Description | I'm importing STEP files using OCCT 7.8 and there is a discrepancy in the model’s coloration depending on the representation. Basically, when the STEP file has an exact representation of the geometry (via ABSH for example), the colors are correctly retrieved. However, STEP files with tessellated representation (via TSH, supported since v7.7) do not pick up the override colors. I produced a simple example that I am attaching to this ticket to illustrate the problem. In them, I have a red parallelepiped, but with a single blue face. The CatiaCube_NoTess file is imported correctly, but the CatiaCube_Tess is completely red. I can’t find the blue color information in it. | ||||
