Sheet sheets are specific parts, which can be developed to a flat state. Therefore, some operations must be performed in a specific way. An example is the division of sheets or cutting the plane.

I have already written about some aspects related to cutting – Article below.

Thin-wall extrusion and perpendicular cutting in sheet metal

 

Imagine a sheet of sheet metal, which is symmetrical. Then a natural solution is to work with half the model – So you have to divide it somehow.

If you use to divide cutting surface (as a plane) or you will use a command Split, The model in the cutting plane will lose the necessary edges (View on the left)! However, if you cut the sketch perpendicular to the thickness – This problem is not there (View on the right).

The effect on the left version will be such, that it would not be possible to make mirrors relative to such a wall. In general, this may cause additional problems with the model, but they can usually be developed flat.

How to divide the model then, so that such a problem would not occur?

I wrote two paragraphs above about it. Use cutting with a sketch or “division with a sketch”, We do not use the operation for this Split. You must draw a rectangle, not a single line with a minimum width – e.g. 0,01 The 0,1mm.

Cutting a single line with an option does not work either Thin walls, Because then the option cannot be selected Cuts perpendicular, which is responsible for these edges.
