File size

Polar Bear

Hello All,


I am fairly new to Archicad (3 years), coming from revit env. 


Currently working on

- Archicad: a small house of around 4K sqft located in a cold climat, the file size is around 177 MB and runs super slow on my comp.  No plumbing done and limited furniture on the file.

- Revit: a housing project of around 35000 sqft, file size is around 155 MB with all furniture and plumbing. Run super smooth on the same computer.


My time to spend playing around with Archicad settings is extremely limited and so is my time to play with computer os stuff, i am really not an computer/ coding person....  But what am i doing wrong?  These Archicad project have become frustrating to work on...


Thanks for your kind help.

From my own experience:

- One of the bottlenecks could be large imported dwg or exploded pdf files (or any other non-Archicad source: 3ds, obj). We often use them for the situation context, but these are made up of thousands of small lines, curves, ect. 

- Sloppy modeling

- Lots of morphs

- very complex or sloppy complex profiles
