North Symbol connected to Project North

Anonymous
Not applicable
Tried a search for this, but with no luck.

Can anyone please tell me how I can link my home made north point to the project north, so that if I change the angle of the project north, the symbol updates to the same rotation too?

I am guessing that I'll need to add some parameters and code?

Thanks for any helpful replies.

Hunter.

I'm not into GDL myself, but it occurs to me you could open one of the north pointers in the Archicad library and extract the code from there?

Hunter:

The global variable is GLOB_NORTH_DIR (old school version U~), see the GDL Reference Guide, page 215.

Just open the project north symbol delivered with archicad. The code is all there. 😉

Thanks for your help - I copied the code and all was well!

Is there a north arrow that can be set that will reset the sun and true north coordinates, or is the only way to set that going to the 3d sun settings click more sun and set it there?

Actually - it wasn't. I can't stop my north point rotating around the bottom left corner of the part. I would like it to rotate around it's center when updating to the Project North direction. Is there a quick way to fix it?

Thanks.

I speculate that the code rotates around the origin of the object. Try to fix the problem by dragging your symbol's center down to the bottom corner from where it now rotates. It should then rotate correctly.......

When I made my part, I selected the elements (which were centered on the project origin) and selected save as library part. But it still rotates around the bottom left corner. I am not sure how else I can move it. If I just copy and paste the symbol into the 2D Symbol window, then I can't use the GDL code copied from the AC North Symbol.

Any more help appreciated.

Hunter:

You could post the code from the 2D Script, maybe someone will be able to tell what is going on.
