Polylines: Are 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.

Shortcut

PL

- So Polylines can be constructed from scratch using the PL command or converting an existing set of standard lines using PE (poly edit) command.

Poly Edit enable 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 especially 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.

Pink - Fit Tool

Orange - Original

Watch out for Gaps.

Dimensioning …

Always add Dimension 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 settings 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 viewport > choose display locked > yes!
