SLADE Documentation - Line Drawing

Line drawing is probably the tool you are going to use most to build maps in SLADE. Here's a breif overview of SLADE's line drawing capabilities.

To start drawing some lines, simply press space (by default, this can be changed). A point will now appear underneath the mouse pointer, at the nearest grid point if grid snap is on:

To place the first point, simply left click where you want it. Now as you move the pointer around a line should appear from where you clicked, to the nearest gridpoint to the mouse cursor:

Now there are 2 different ways to finish line drawing: creating a sector and splitting a sector. Firstly we'll look at creating a sector. Basically all you need to do is place points in the shape you want, and place a point over the first point to finish drawing. If you add the points in a clockwise fashion you'll create a new sector, anticlockwise and you'll create a 'column' (which must be within an existing sector). Here's an example of creating a simple closed sector:

And here's an example of creating a column:

You can also draw over existing lines to 'add' a new area to a sector:

Now for splitting a sector. To do this, instead of drawing the entire area you want to create, you draw a line (or lines) from one side of a sector to another, and click on the end point a second time to finish drawing:

You can also create new areas attached to an existing sector using this method, like so:

Pretty simple stuff :P. There are a few other things to note. If you draw a point by mistake, you can right click (default) to cancel that point. If you cancel the first point you cancel the line draw. Also, middle click (default) will add a point at the closest existing vertex to the mouse pointer.

That's pretty much it for basic line drawing. Now we'll look at the rather useful shape drawing feature.
