I am studying sketching. If I draw a rectangle, I find that lines are already connected. Each vertex is a point object.
Is there a way that the connection can be broken, so that I might get an open rectangle; and then, reconnect?
Sure you can. Just use the Power Trim. Watch this video:
only with some manual interaction.
1) you could add lines crossing near the corners and use the trim command to remove the corners.
2) use the sketch fillet or sketch ckamfer commands to remove the corners, then delete the chamfer/fillet
3) use the split entities command to split the lines and judiciously delete line segments to leave teh edges you want.
I have tried every single one of your methods and they all worked. Thanks very much!
Sorry for replying late. In my country this Youtube video has been blocked and it took me some effort to finally being able to view it. It is the simplest approach, thanks!
Tools > Sketch Settings > Detach Segment on Drag
This is also convenient, thanks!
Yes you can; you can use "Detach Segment on Drag" it is a toggle
You can get to menu>Tools>Sketch settings.
corrected - sorry didn't see Kelvin's response - Good call Kelvin...
I have tried that, thanks.
I have an additonal question on the algorithms of Solidworks. I think for CAD systems as advanced as Solidworks its implementation should be an ensemble of most computer graphics algorithms. I tried to give it some thought and found that even for basic tasks like detecting interference between objects there could be lots of challenges. Does SW uses OBB tree for this purpose?
