| Summary | 0032239: Data Exchange, STEP import - bounding box is too large | ||||
| Description | The bounding box is too large for the attached STEP file. The X range as reported by CAD Assistant is 157.233mm. However, measuring the X range in another viewer (eDrawings) shows 106.182mm. The Y and Z range is also too large. | ||||
| Steps To Reproduce | Open the attached file in CAD Assistant and get the range. Measure the range some other way and compare the values.

STEP import produces 4 unorientable Faces (for lenses). So the problem could be reformulated as fixing STEP import to produce a valid shape (or to determine that specific STEP file is invalid and has no proper fix). Afterwards, bounding box on fixed shape should has expected dimensions. -- The Shape s has problems : Check Count ------------------------------------------------ Unorientable Shape ....................... 4 Not Closed ............................... 4 ------------------------------------------------ *** Shapes with problems : 8 WIRE : 4 Items -> compound named s_w FACE : 4 Items -> compound named s_f -82.043211434255824 -97.41395356722937 -97.41395356722937 73.632312330445473 97.41395356722937 97.41395356722937 |
