Rotating Door/Window Markers

Red — Wed, 24 May 2023 10:50:27 GMT

How can I get the markers to automatically rotate. I noticed that it has something to do with reveal_side. Any help would be great.

ROT2 -W~

W~ is the global variable identifying the object angle. If you rotate the marker by an equal angle in the opposite direction it stays aligned on your drawing.

I used to have problems with this not working properly in 6.0 and 7.0 (mirror reversed or flipped doors would confuse AC no end!) but in 8.x it seems to be working properly.

Now you can maybe help me with another related issue: How can I get the marker to return the door's ID as a number, instead of it's own ID? I used to be able to do this (when I was having alignment problems in 6.0) but now I can't figure out how to.

And, if you look at your GDL Manual (PDF) appendix section titled "Global Variables", you'll see that (several versions ago) Graphisoft introduced synonyms for all of the globals to give them more readable names:

SYMB_ROTANGLE means the same thing as W~, so

ROT2 -SYMB_ROTANGLE

gives the identical result as Daniel's code.

In general, using the new names is recommended to make your code more readable / understandable. Experienced old-timers and many old library parts (including much of the standard library) still use the old abbreviations ... which require the magic decoder ring from a cracker jack box to figure out.

Do I have to alter GDL script? to rotate the attached markers?

Funny thing... a couple of doors on a lower level have markers with correct orientation. When I "eye dropper 'em" and place them on this level, the markers flip.

I do not have the marker objects, because I am using INT and HUN (garian) versions, but you should be able to do it. Probably either an ADD x,y command in the 2D Script should do it.

You need to find the linein the 2D Script that creates the width/height text.
It will probably be a TEXT2 command.
Then you need to insert an ADD command before it, then a DEL command after it.
The ADD command will move the location where the TEXT command generates the text, the DEL command undoes the ADD command so you get back to where you were before the ADD command.

Something like this:

ADD 0, y
Text command generating width/height
DEL 1

The y value will probably be a negative number.

It seems door markers care which direction walls are created when deciding which way to orient the "Builder Dimension".

Cool for us who are GDL-script-phobics.
