AutoCAD/object - layers

Question
Here I am again! Can one object belong to a few layers?

Answer
They can, but it is not a good idea.  When you make a block, the objects within should all be on layer "0".  That is so that when you place the block on the correct layer, it will take on the properties of the layer like other objects on the layer.  You can override color and linetype by making the color or linetype of objects within a block "byblock" or assign color or linetype directly on the object.  But don't place them on any other layer, because when you start doing layer control you might want to freeze one of the layers in the block.  So, take my advice and just draw the block contents on layer "0".

Other objects can only be on one layer.  However, multiple objects in a drawing can be grouped with the group or -group command.  The group can be named or unnamed (an unnamed group is really an automatically named group).  Unnamed groups really do have names and they look like this: *A1, *A2, *A3, etc.

Expertise

I can address all 2-D questions and some 3-D questions. I do programming in AutoLISP if it doesn`t involve solid modeling. I can also address menu customization issues and can help you find answers to questions I can`t answer by taking your question directly to Autodesk via their newsgroups.

Experience

I used to do electronic and mechanical design for a flat panel monitor manufacturer, and now I do architectural drafting for an architect. I did and do AutoLISP and menu customization and take pride in making my lisp routines to do the work exactly the way the client likes them done.

Publications
I had a routine published in CADENCE magazine (no longer in publication and taken over by CADALYST). Some of my routines are published on my website at http://my.sterling.net/~bdeshawn
