[esp-r] Import model from AutoCAD

[Paulo Tavares]

Hello all!

I'm trying to import a building from AutoCAD to ESP-r. But the errors don´t 
stop... Can anyone tell me something about this? Where i can find more 
literature about this (the cookbook is not a good help... and the tutorial 
web page also...)? Anyone knows an interface to do this? Or, by your 
experience, it is preferable to make the model using the ESP-r CAD or bitmap?

Thanks very much.

Regards,

Paulo Tavares
