Do you know, that… ?

There are sometimes situations, in which you can not directly create sheet. One of them must sketch wielokonturowy.

Typically, such a situation we have to do when importing DWG / DXF files, where such. bending lines are not recorded on the layer (or deleted). Of course, you can manually remove unnecessary opening sketch entities, but you can also use extrude selecting areas, and then insert bend.

another situation, that prevents the sheet once the initial offset sketch. In any operation sheet, I think in particular of deflection of the base, You can not move a sketch in the status of the beginning.

 

Because then we can use extrude and like the previous operations in the next turn on the block sheet metal.
