is it possible to work on the Archicad 26 trial version?

[LeeJaeYoung]

I'm trying to study API at archicad 26.
1. Is it possible to write with visual studio 2019 community?
2. Since I am studying personally, is it possible to work on the Archicad 26 trial version?

3.Can I download this and use it?

[BerndSchwarzenbacher]

1. Yes this works. I'm using Visual Studio 2022 community, but 2019 should also work.

2. I started out using the Archicad 24 Trial Version. So I assume it's possible to also use the Archicad 26 Trial Version now.

3. Maybe it's better to get the x64 version.

[LeeJaeYoung]

I've never used x64. Are there any advantages?

[BerndSchwarzenbacher]

You are running Windows 11 which only comes as an x64 version I think. When you use x64 versions of programs, then you skip the WoW 64 translation layer. In practice it probably doesn't make much difference for AC Add-On development.

However, in the trial version, you cannot study GDL. How can it be done?

[BerndSchwarzenbacher]

Isn't the trial version fully featured but only available for 1 month?

I think you mean the DEMO version maybe?
You can use the LP_XMLConverter as a workaround.
Check the help for it in e.g. PowerShell (adapt the path according to your installation):

& "C:/Program Files/GRAPHISOFT/Archicad 26/LP_XMLConverter.exe" help

 
Here's a more detailed workflow:

1. Pick a .gsm file from somewhere and run:

> & "C:/Program Files/GRAPHISOFT/Archicad 26/LP_XMLConverter.exe" libpart2hsf test.gsm test/​

2. You have a folder with .xml and .gdl scripts now. Change them to your needs.

3. Convert back to a .gsm file:

> & "C:/Program Files/GRAPHISOFT/Archicad 26/LP_XMLConverter.exe" hsf2libpart test/ test.gsm
