3D model -Extension to an existing buidling.

Hi,

I'm new to this so please excuse my ignorance.

I require a 3D model to be created of some 2D drawings that have been created by an architect.

I need this as the client is finding it very hard to visualise the scheme.

The 3D file will need to be done sone that i can open it up in Sketchup with various layers etc so that i can dissect it if required.

I will also need to be able to export it as a "STL" file (i hope that right) so that i can get a 3D model printed.

Please see the attached drawings for your information. (I have the original PDF's which can be forwarded once we agree a price)

Please could you provide me with a fixed price for completing these works.

Thank you

Carl
