i have been using LibreCAD recently, i have created many blocks in a particular drawing. However, when i opened a new drawing for a new project, these blocks weren't available. Also when i checked Blocks folder in LibreCAD directory in my PC, it was empty.
Can someone advise, how to centralize these blocks and make them available for all drawings?
At first blocks only exist in the drawing where they were created.
In the Blocks List there is "save the active block to a file". Do so and place it at the existing Library or define a new one. You then can import it into a new drawing.
There is no way to have all blocks you have ever created automatically available in any new drawing.
