How to edit decimal precision of Param-O object parameters in GDL?

Rogerio M — Thu, 10 Jul 2025 09:26:35 GMT

Hello!
I created an object in Param-O and then continued editing it using GDL, I have very limited knowledge of it, but I managed to add vertices, fills, and similar elements. After some trial and error, I reached a satisfactory result.

However, in the object's settings interface, the custom parameters I created are limited to only 2 decimal places. I need the precision to be 4 decimal places, but I couldn't find a way to change this in GDL.

Could anyone help me with this?

Could it be that those are not stored as "Lengths" by GDL but as "Floats"?

Just go and switch those (click on the icon to do that):

But beware! Whenever you switch the types of a parameters Archicad will delete your current number in there!

So first copy the number, then switch, then paste back in to prevent data loss.

Hi Runxel,
That was exactly it! I was a bit lost thinking it was some script I needed to add.
Thank you so much!

@Rogerio M,

You could also try setting the value in the "Numbers without Units" field of the Options > Project Preferences > Working Units Dialog to a value other than 2. If think the accuracy of all values that do not have a dedicated field (like Length, Area, Volume, Angle, Layout Unit) is controlled by this value.
