Arrows...

This is where you edit and specify the sizes of the various arrows that are available in the Windows >> Attributes pallet.

There are five arrow types available:

Open disc – two options
Closed disc – two options
Open arrow – two options
Closed arrow – three options
Slant line – one option

Open and closed disc are specified by Radius as the near-right pane.

Open and closed arrows and the slant line are specified by Angle and Length as the far-right pane.

Click on the arrow you want to edit (from the selection along the top) and then edit it to your requirements. Click the Apply button and then Close.

Tip: A radius and/or the length that looks about right at, say, 1/10 scale will be rather insignificant at 1/1 scale, so it's useful to specify one size for scales in the 1/30 to 1/10 range and another size for arrows in the 1/2 to 1/1 range – or whatever common scales you use on your drawings. Experiment a bit to see what looks right on your drawings! I find 2 pixel discs and 15º, 6 pixel length arrows work well at about 1/30 to 1/10 scales.

Dashes...

This is where you edit and specify the sizes and arrangements of the dashed lines that are available in the Windows >> Attributes pallet. Ten preset lines are available.

The pane to the right shows how I have a long-dash/short-dash line set up:

L1 is the length of the first line. In my setting, 6 pixels.
e1 is the gap between the first and second lines. In my setting 3 pixels.
L2 is the length of the second line. In my setting 3 pixels.
e2 is the gap between the second line and the start of the repeat of the first line. In my setting 3 pixels.

To make a dashed line where all the dashes are equal, set L1 and e1 to the lengths you want and then set L2 and e2 to zero.

Tip: For a dotted line set L1 to 1 pixel and e1 to 2 pixels; set L2 and e2 to zero.

Tip: As with arrows, you may find that you need to have dashes for scales in the 1/30 to 1/10 range and different dashes for, say, 1/1.

Once you are done, click the Apply button and then Close.
