Use Lisp Routines to Clean-up Drawings
There are several new .lsp (lisp) routines available for our use, some of which will make it easier to get rid of annoying "empty" layers that seemingly can not otherwise be deleted.
Delete All Items on a Specified Layer (filename: delayer.lsp)
This command is useful if the Purge command does not eliminate unwanted layers, and should only be used if, with ABSOLUTE certainty, it is determined that there are no desired elements drawn on an unwanted layer. Often, after purging a drawing, it may become impossible to delete a layer that 'appears' to be unused.
Upon performing a thorough visual scan of the drawing, it may still appear that the layer is unused, yet Autocad will not allow the deletion of the layer. The DELAYER lisp routine bypasses this roadblock.
CAUTION: This routine actually erases anything that is drawn on the specified layer(s).
How to Use It
On the Command line, type DELAYER, and a dialogue box appears which will lead you through the proper steps.
This lisp routine is "current view-contingent;" If the unwanted elements drawn on a given layer are drawn in Paper Space, it is critical that Paper Space is the active view prior to performing the lisp routine.
Move All Items From One Layer Onto Another Layer (filename:movlay.lsp)
This routine allows the user to move all elements drawn on one layer to another layer. It is useful if you are editing, or cleaning-up a drawing, and elements are drawn on the wrong layer. You can move these elements to the proper layer through this one command.
One may use this command if there is uncertainty as to whether any unseen elements on the given layer may still be useful in the drawing, even if that usefulness is not apparent.
How to Use It
On the Command line, type MOVLAY, and a dialogue box appears which will lead you through the proper steps.
Add Properly Scaled Batt insulation EVERY Time (filename:insul.lsp)
This routine allows you to add insulation batting to your drawing when you already know the starting point, ending point and thickness of the insulation. Rather than using the ACAD2000 batting linetype and "guessing" which scale factor to use for a particular viewport or viewports, use this command and you will get a consistent 'look' every time.
This routine is best utilized while drawing details, as opposed to showing batting on floor plans.
How to Use It
On the Command line, type INSUL, and a series of prompts appears on the Command line. Basically, with the mouse, pick the start point of the batting, type the batting thickness if known (or use the mouse to define a dimenion thickness), then pick the end point of the batting. Try it a few times with a simple door jamb detail to get a 'feel' for it.
