GDL - different 2d view according to scale?

[Bawar Tanay]

Is there a way to GDL code a 2d view in a way that it becomes automatically different according to the scale?

like for example if below 1:50 = view 1

if above 1:50 and below 1:100 = view 2

above 1:100 = view 3

same way as you have with model view options objects detail level?

Thanks

Hi

one way:

IF GLOB_SCALE <= 50 THEN
     ! view1
ELSE
     IF GLOB_SCALE <= 100 THEN
          ! view2
     ELSE
          ! view3
     ENDIF
ENDIF

another way would be

IF GLOB_SCALE <= 50 THEN
     ! view1
ENDIF
IF GLOB_SCALE > 50 AND GLOB_SCALE <= 100 THEN
     ! view2
ENDIF
IF GLOB_SCALE > 100 THEN
     ! view3
ENDIF

It's a sure thing. 😉

Sorry I couldn't resist.

I was also going to say - "quit while your ahead". 🤣

Hahahahaha

Will share the price money with you, or split the losing 😄

Quitting is not an option hahaha

it works quite great, love the logic behind GDL, but there is a lot of learning for me to do.

Especially Graphic User Interface – I just don't understand how that works or the macros for example.

Anyway, I figured it is important to sketch the outcome you want

and write all the requirements of that object before you start coding. 

It makes life easier.

GDL is quite simple yet quite complex at the same time.

The best investment I ever made was the GDL COOKBOOK 3 by David Nicholson-Cole.

It is very old (so not up to date) and you can't purchase it any more.

But if you Google it you will find a PDF version (4 which is a little more up to date).

The basics in the book are still all applicable - it just doesn't include some of the newer commands.

It has a few bits on the user interface.

I still refer to it some 20 odd years after it was published.

Barry.

besides bets on horseracing i basically use 4 different sources 😉

• opening random objects in ArchiCAD (select an object and Ctrl + Shift + O) and try understanding how it was written
  • you can find out how GS did the sheep easter egg in the change marker tool 😉
• ArchiCAD GDL Reference
  • check out the style guide
• https://www.selfgdl.de/ but it's in german
