I am using AutoCAD 2002. I have a number of drawings, created by someone else, all drawn in single layer.
In one of them, I created a number of layers, with different colours and plot styles (linetypes). I used these layers to distinguish different entities in the drawing.
As other drawings too had similar entities, and I wished to apply the same layers to them also, I saved the layer state in the frist drawing, exported it, and again imported in in the secong drawing. I got all the layers rightly, and used these layers on entities. So far so good :)
But, when I opened third drawing, and impored the .las file (which I had used in the second drawing also), although I got all the layers, they all had one colour (white), and one linetype (continuous) only. I opened the .las file, and it did show different colours and linetypes for various layers. I then tried importing this file into a few other drawings, and got the same result - all layers were imported, but without their original colour and linetype.
So, I opened the second drawing (into which the layers were imported successfully) again, deleted the exisiting layer state in it, and again imported the .las file. The layers were imported correctly here.
Where am I going wrong with other files where layers are not getting correctly imported ?
