    Hollow core slab makes files too big

    Hello

    I'm having problems with one of hollow core slab family. The biggest problem is the size of it. Using it in 5000 square meter building makes it over 5 times bigger than it originally was. IFC files are going to a gigabyte and when switching to a basic Autodesk family it goes back to 50 or so Mb. Could someone give a look and see what is making it so big

    Second problem is when i cut it. It has a masking region on it to hide the lines which are created by the edge. When the slab is cut by face then the masking region dissappears totally and the nasty multi-edged slab appears.

    Does anyone have answer to ANY of my questions. Any help is welcome.

    As I have played a lot with this family I realized that the complexity of the shape has been pumping up the size of the file
    Is there any way to make it smaller?
    Any ideas at all...

    If someone cares then I solved the problem by creating two sweeps. One which is used in medium detail and is just a solid block and one with the holes and profiles. As i create IFC i simply change the detail level to medium which shows the solid blocks and the holes through the beams are shown and IFC size is reduced from 700mb to 7mb

    If I have too model Hollow Core Planks I just model the whole area as a Slab/Floor with the thickness and material of the Hollow Core plank. Then in Section I have a 2D Family of the Hollow Core Plank that I just drag and drop in the section and detail views. Otherwise your model size does go through the roof.
