When creating cut-extrudes on sheet metal models, it is recommended to choose the Normal Cut option under cut-extrude properties. What if a cut has already been made on a sheet metal and it is not normal? It could even be made by cut-loft feature. In SOLIDWORKS 2018, a new feature has been added to the sheet metal toolbar to convert tilted cuts on sheet metal to normal cuts.
Creating a Normal Cut
In the following a sheet metal part is shown with a hole in the middle. The hole is cut using cut-loft. Therefore, the sidewalls of the hole are not normal to the face of the sheet metal.
Now if we use the Normal Cut feature under sheet metal toolbar or under Insert > Sheet Metal; we can make the hole sidewalls normal to the sheet metal. Here is how:
- Click Normal Cut
- In the PropertyManager, under Faces For Normal Cut , select Auto Propagation
- In the graphics area, select the face of the cut (The software selects all faces of the cut)
- In the PropertyManager, under Parameters, select Extent. With Extent, the maximum amount of geometry is cut based on the outline at the top and bottom face
- Click the green checkmark. The faces of the cut are normal to the top and bottom faces of the part (see below).
