Week 10 AutoCAD Layers Review Array Review Wipeout
Polylines – PL Continuous lines – made up of various segments – they can be used to construct closed areas for hatching and many other uses including preparing drawings for laser cutters or CNC machines. Polylines can be constructed from scratch using the PL command or converting a existing set of standard lines using the PE (Poly Edit) command Poly Edit enables us to join a series of lines together to create a continuous polyline – select a line – turn it into a polyline then join additional lines BEWARE: If your lines do not meet (have gaps) – you’re probably not using the OSNAP Options.. Turn OSNAP on (F3) and make sure the lines are connected – use the fillet or trim tools.. Lines that don’t meet can cause a whole host of problems when applying hatching/laser cutting etc…
We can create complex curves by transforming a Polyline (PL) using Poly Edit (PE) – use the fit option or spline option
Blue Line –Line using fit Red – Original polyline Green – Line using the spline option
Hatching – H Watch Out for gaps!
Dimensioning Always add Dimensions in paperspace Always use the Annotative setting – this means that the size of the dim changes for you depending on the scale of the viewport – you don’t have to work it out
To change the setting of the dimensioning use the Dimstyle command to bring up the Dimensioning editor – here you can alter all the dimension settings You may want to lock the viewports when adding the dims – as they can easily move – select the viewport right click on the view port choose display locked yes!

Make sure you’re in paper space (NB – no thick bold outer line) when you add dims and states paper here…
