In AutoCAD 2011: Tips, Tricks, and Industry Secrets, Jeff Bartels shows AutoCAD users how to become more efficient power users, reducing the amount of time it takes to accomplish a task, increasing profit margins, and strengthening marketplace competitiveness. The course covers everything from shortcuts used in geometry creation, to program customization, to real world solutions to common problems. Interface customization, block and reference management skills, and express tool usage are also covered. Exercise files are included with the course.
Has this ever happened to you? You receive a drawing from a client and in the process of converting the drawing to your layer standards you find a layer that you just can't get rid of. Even though it appears that the lawyer is not being used, AutoCAD will not purge it out of the drawing. In this lesson, we'll learn how to take absolute control of a file and delete any layer from any drawing. On my screen, I have a floor plan that I received from a client and I'm just about ready to incorporate this geometry into my project. However, I seem to have a layer that I cannot remove. It is this one, called ARCHLAYER.
Now, I've already used the Quick Select Tool and AutoCAD told me there's no geometry on that layer. I've also tried the Purge command and AutoCAD says that layer cannot be purged, so the layer is being used somehow. At this point, I can only assume that there is a rogue entity on that layer that's buried inside one of these blocks. Looking at the drawing it appears that I have all the geometry that I need so I'm going to tell AutoCAD to do whatever it takes to delete that layer. I'll do that by opening the Layers panel in the Ribbon and I'll select the Layer Delete tool.
This tool will seek out and delete any rogue entities, even if they're part of a block definition. It will then purge out the unwanted layer. I am going to right-click and I'll select the layer by name. I will then make sure that the ARCHLAYER is selected and I'll click OK. And AutoCAD then issues a warning to let me know that all entities on that layer will be deleted. I'll click Yes and if we check out the Layer Properties Manager you can see that the ARCHLAYER has been removed. You know, as a side note, if you look down here at the command line you can see the block called floor plant has been redefined so it might be worth taking a look at that block to see if anything is missing.
In this case, it looks like everything is okay. So the next time you feel like you're being held hostage by the layers in your drawing, try using the Layer Delete tool and have the final word on removing a Layer.
