is there a place where i can see my recent downloads?
If you liked that model before or after download than it would be in your likes folder.
Go to Community>My likes.
Under community there is drop-down menu just take your mouse there and click on button My likes.
If you not liked that model than simply go to your browser history and search for the name of your model you downloaded than click on it.!!
Grab-cad didn't have the facility to see the downloaded model history.
