Straighten the page by two points

Click two points along a line that should be level and the sheet is shown turned by the small angle that makes it so.

Why you would use it

A scan or a photographed plan that runs a degree or two uphill is tiring to read and awkward to measure along by eye.

For example

What to do

1. Open it from View, or search for it in the command palette.
2. Click one end of a line that should be level or upright, then the other.
3. The status bar says Straightened; click it to put the sheet back.

Going further

It’s only how the sheet is shown, like turning a page to read it. The file isn’t changed, every mark and measurement is still held in the sheet's own coordinates so no quantity moves, and an export or a comparison is made from the sheet as it is. It can be repeated to finish the job and goes no further than 20°; for a quarter turn, turn the page. The magnifier follows the turn, using the page as it was drawn, so on a straightened sheet it’s a little softer than usual. Straightening is for this sitting and starts again when a drawing is opened.
