north object

Anonymous — Mon, 03 Sep 2018 21:11:36 GMT

Hi!
I would like to create north object that follows north set in project preferences, but when rotating to do that around specific point/hotspot.

I know that syntax for that is rot2 GLOB_NORTH_DIR-90
But how can I define a hotspot that is the center of rotation?
Is it possible to add text to this hotspot?

Just checking that none of the various 2D choices for the existing North object are satisfactory? Since it has an option to follow project north already...

Yes, none of the existing options are not satisfactory.

Assuming there are no transformations before your 'rot2 GLOB_NORTH_DIR-90', you need move (ADD2) your elements so they sit at the specific point you want to rotate about.

This is my code.
I have tried with add2 but I don't know how to use it.

I think you can remove all of the ADD2's in your script as long as you saved the object with the rotation point at the project origin.

the add2 command works like so,

add2 0, 1 = move 0mm along x axis and 1000mm along y axis.
add2 1, 1 = move 1000mm along x axis and 1000mm along y axis.
add2 0.5, 0.5 = move 500mm along x axis and 500mm along y axis

Or if for some reason you need those transformations, place them before your glob_north. Though given that it is an automatically generated script, I guess it is not intentional. They are the culprit of your rotation issue. You have set a rotation point, then moved the center of your object off that point.

Adjust the first ADD2 command in your script so that the following fill, hotspots and lines are positioned on the origin at the point that you want to rotate around - you can see this in the 2D preview.
The rotation centre point is at the origin so you need to position your elements in relation to this rotation point.
