Hello all,
I am starting with AutoCAD at university so I am rookie who is trying to get how things work in short time.
I am pretty confused while working with lines or polylines. We obtained dwg file of 2D airport with existing polylines as taxiways. It has its own defined layer, but they are all edited with global width of 0.2.
This is what I found:
In Model Space, lineweights seem to increase in size while zooming out and decrease while zooming in.
In paper space, lineweights seem to stay constant.
New ones behave differently. I've drawn some lines with the same layer as existing ones, but now with global width set to 0 in order to get defined lineweight. If I zoom in or out in model space (not paper - here all lines are static), those lines do not change width at all. Is this behaviour normal? I enclosed pdf with a cut of created objects with polylines. Left (thick) is set to global width 0.2 and does not change while zooming, second one's lineweight is set BY LAYER (layer is defined 0.2mm) and third is manually set to 0.2mm. Why those objects appear different, when all are set to 0.2? What's the purpose and difference of using lineweight and global width?
Thank you all claryfing this to me. 🙂
