So I imported a DXF as a 2D file sketch. I don't seem to have the option to undo. Unfortunately can't attached the file here (confidentiality...) but would like to know if it's a known issue.
I don't understand. What you want "undo"? If you don't need this sketch - delete it.
I'm deleting lines, one by one. Lines I don't need. I need the sketch it's just that it comes with a lot of extra stuff that I gotta clean out BUT if I accidentally delete a wrong line I need to start the whole process from scratch! I noticed that it seems to happen when the imported sketch has a lot of components. If the sketch has fewer components undo works.
What about trim tool? If you accidental trim line , you can untrim it.
I suppose you have a problem because you are editing a block. First exploding the block (as Habib Ghalamkari wrote)
How do you import the DXF file?
In SW 2020, I created a blank part, dragged a dxf file into the part, selected the origin to import the dxf and clicked OK.
The DXF imported as a block. Either after exploding the block or editing it, I was able to undo the delete by ctrl+Z.
What's your SW version?
You could use a free 2D software and edit everything in there, then import to SW
Valery, it has an undo option. Let me explain to you, when you use internet browser and if you search for anything and click on a certain webpage, and you don't find well information you can always go back by pressing left arrow button. Same way here in the SOLIDWORKS there is an available left arrow and right arrow use as per require before pressing save button. If you do save then the left arrow and right arrow will not respond until you have not made your next move. I hope it helps.
Hello Valery,.. maybe because "Automatic Solve" is not on? (see attached)
