Adjust Command (to extend lines in 2d)


Hi all,


I cannot seem to use the adjust command! I just can't figure out how to use it and cannot find any clear video tutorials explaining it. I have made a video highlighting the issue that I am having here:


Any help would be greatly appreciated!


Thanks, All.

Select the lines you want to extend. Hit Ctrl + - (or use the adjust menu commands / icon) and click the edge you want to connect with. You can only use one edge e.g. it doesn't work with a polyline. Simples. There is also guidance at the bottom of the screen if you occasionally need it.

As DGSketcher says, invoke the command shortcut (CTRL+- that is CTRL and the minus key) or use the tool button.

Then click the line you want to extend to.

And note that the Adjust command an be used not just to extend lines/walls, but also to split them if they extend beyond the adjusting line/curve...


In your video, ctrl+- (cmd+- Mac) should work... and I can see you are getting the prompt at the bottom left line of the screen to click on the line to extend to...and assume you clicked your left mouse when the mercedes cursor was on the line.  If it didn't extend, I'm guessing that you might have a snap grid turned on or something (although in that case, your other more tedious methods to extend the lines shouldn't have worked).


What is odd/fishy in your video is that when you select the 3 vertical lines, the Info Box says that you have 6 lines selected.  Even if there are duplicated on top of each other to get to the 6 vs 3, it should still work. I've never had it not work, so I'm kind of out of ideas.  Sorry!
