AutoCAD layer is a great feature to manage objects in your drawings. What we don’t like about it is we often need to change layer before we draw. For example when we want to draw dimensions, we need to change the layer to dimension layer. Then change the layer again when we need to draw other objects.
You can create a macro command to do this automatically. Of course, you can use LISP. But the good thing about macro is you can use it in AutoCAD LT too.
The command macro
If you are not familiar with AutoCAD command macro, you can read this excellent tutorial by Paul Munford.
The macro code for this macro is very simple:
Replace DIMENSIONLAYERNAME with your dimension layer. This layer must exist in your drawing for this macro to works.
Using the macro
There are various ways how you can use the macro. The easiest way is to place it in tool palettes as described in this tutorial.
A more advanced macro
The macro above will work great. We can make the macro to change the layer back to the previous layer immediately after the command is finished. So when you are working with wall layer, create a dimension on dimension layer, then the current layer is back to wall layer.
The macro will be:
This macro will allow you to create dimension on dimension layer. Then change the layer back to previous. However, if you press Esc key before the dimension is drawn, the layer previous command won’t be executed.
What is your favorite macro command?
There are many ways to customize AutoCAD commands. A custom command can help you to work easier, even if it’s only a simple customization.
