I am usually copying or moving odjects in AutoCAD LT by slecting the object, start the MOVE or COPY command, pick the base point, move the cursor away from the base point along either a polar snap angle or the vector of an object's side, and type the distance I want to move or copy. When I had v2010, the snap would hold while I typed the distance so that I only had to hit enter after typing the distance. Now, with v2015, the cursor on the screen loses the snap (either to the object or the polar angle) while I type the distance. I now find that I must move the mouse again and reaquire the snap before I can hit enter to get the movment along the vector that I intended.
What has changed between v2010 and v2015 to make this happen and is there a way I can set preferences so that AutoCAD LT v2015 maintains the intended snap while I type in the distance? Wait -- I found it. It's under User Preferences and is called "Priority for Coordinate Data Entry". I set it to "Running object snap" and it seems to behave the way I want.
We had the same problem in AutoCAD 2014. In the moment we find some unusual solve - change your workspace to AutoCAD classic. Then off all your tabs. After that type in command line "Ribbon". As a result of these moves you have ribbon pannel such as 2d drawing workspace and perfectly working snaps when typing. MB later we are find the reason of these bug/specific work... But as i know in 2015 autocad there isn't classic workspace after install...
