Splitting/trimming issue

Hi there, I have been stuck with an issue for a while now and hope someone could assist me.

I have attached the model. There are 5 blocks representing a terrace house. The roof is somewhat complicated so I approached the modelling by creating 5 blocks and then take away the parts I don’t need. I had various issues with lofting and surfacing but I have finally arrived to the part where I just need to split the blocks into two with the surface created. I tried the trimming command and than splitting command, none of them worked. I had more success with splitting but for some reason, the two blocks on the side won’t split. I tried scaling up the surface in case it doesn’t intersect with the blocks but that had the same issue.

Any ideas, suggestions would be greatly appreciated !

Hi, your model suffered from some imprecision, attached is fixed.

That’s amazing, thank you so much for your help ! What did you do exactly? I wonder where I messed up…

Ah, you just have to draw it more precisely for the trimming commands to work.

There was unnecessary data in your model that prevented the command from working.

Be more careful :slight_smile:
