purge file

Lasha97 — Wed, 27 Aug 2025 13:14:27 GMT

I was given an Archicad file which is quite heavy; it takes a long time to open, and even Copy/Paste operations are also very slow. (There are imported foreign 3D models in the file.)

I deleted absolutely everything in the file, but nothing has changed. File is still very slow. is there any way/method I can use to make such a file faster?

Operating system used: Windows

Absolutely everything? 2D content in elevations and sections? Schedules? There can be a lot of data in all of the different views. There is a thread somewhere around here regarding creating a lean template or something similar.

Hi,

Firstly I'd open an empty Archicad then go to open - and click open and repair file. That function should optimize it slightly.

However, if the the 3D models are geometry-heavy and non-native there is not much you can do (that I know of) - just request a simplified model from your collaborators (LOD 300 or lower). If you have complex machinery (ex HVAC equipment) for example, you can use a place holder instead (a slab that has WxLxH) to symbolize that piece of equipment.

And you may also try and remove 3D Axonometries, Layouts, etc.

Attribute Purging for Fills and Lines that aren't being used may also clear up some of the speed issue.

Some of the autocad created attributes (if you had a survey dwg, as an example) can really bog down the archicad project efficiency.

And I echo the suggestion of removing unnecessary schedules that can also be sabotaging the file.
