| Summary | 0027622: Data Exchange - STL file having less than 4 triangles cannot be read | ||||
| Description | The appended simple STL file, created by SpaceClaim, cannot be read. The exception says: Wrong file size. However, it can be read by CAD Exchanger and Siemens NX 9. Is it an OCC or a SpaceClaim problem? | ||||

Design1.stl (184 bytes) |

STL reader in OCCT defines minimum size of binary file as 284 bytes (84 for header and 200 for 4 triangles). I don't know where it comes from, but it is hard to imagine the valid file of smaller size. Technically STL file should define a SOLID (closed) geometry, which can be possible only with 4+ triangles. Attached file defines only 2 triangles, which is considered as broken file by OCCT. |
