I have prepared one conveyor chute drawing of 10 thk. plate by SOLID WORKS and get BOM (bill of Material) in 2D drawing. Checked it and found ok. While editing some dimension of existing drawing, I found that automatic revised BOM has some errors. errors are a) Some Items are zero (0) weight. b) multiplying result of qty and unit weight gave wrong answer.
This is a weldment cut list, not a bom.
To fix the problem with the total weight, click on the box with the incorrect value, click the 'Equation' button and type in the correct equation. All items had weight when I opened the files. Try Ctrl Q or close the file and re-open it to fix this.
