GDL: Edges & Centre Points

Lingwisyer — Thu, 18 Apr 2019 06:38:53 GMT

Hi all,

Is there a way to get edge and centre line snaps when using a Project2? Or do all the lines need to be scripted in 2D?

Ling.

As far as I know the hotspots and hotlines need to be scripted in 2D.
Which can be tricky if you are trying to exactly match what you are projecting from 3D (depending on how complex it is).

It would be great if we had a 'show 3D hotspots in 2D' parameter like we do for 2D hotspots in 3D.

Actually, there is a way to do this: PROJECT2{3}. From the GDL Reference Guide:

PROJECT2{3}
PROJECT2{3} projection_code, angle, method, parts [, backgroundColor,
fillOrigoX, fillOrigoY, filldirection][[,]
PARAMETERS name1=value1, ..., namen=valuen]
...
parts: defines the parts to generate. The 1+2+4+8+16+32 value means all parts.
parts = j1 + 2*j2 + 4*j3 + 8*j4 + 16*j5 + 32*j6, where each j can be 0 or 1.
...
j5: project 3D hotspots as static 2D hotspots,

Thanks Durval.
I hope this works for Ling.
I must investigate these new project2 varieties.
I don’t use them often and if I do have just used the old original one.

These commands are new to me also. They look powerful, but complex.

I was coming back to this object and I realised that I had already scripted all of my hotspots, so I just added hotlines between those same nodes. Did not need to work out new coordinates so that was easy enough.

I did consider using Project2{3} but I have hotspots that do not always line up nicely in the z-axis which would have made the 2D messy if they were simply projected up.
