import dwg error in impression 3

[Piron88]

Good morning, everyone.
I discovered hot water with this software I just found out about. But my first approach was not the best.
I tried to open (and also import ) a dwg file with inside the layouts. at the end of the wizard for opening the file (or import ) tells me "filename" is invalid and cannot be opened.
I tried to open it from both layout, viewport and model but it gives me the same error.
for the moment I solved working on dwf but I would like to be able to work on dwg.
Can anyone give me a tip?
Thank you.

by now impression is a little "data" and from that I know no longer maintained. What are you drawing on him? dwg version? if they are 2013 try to retrosalvarli at 2010 or 2007

I'll try as you say.
Or what software do you recommend?? I have the premium building design suite with active sub. Do you know if there's anything inside that allows me to do something like that??

I've been too excited. The problem is I just can't figure out how sketchbook can give me the same impression result. i.e. I have to put "the trick" to the cold and technical autocad plants. and on youtube I find only tutorials on how to draw shapes and what else.
you can tell me some site or forum
