Make objects change layer autmatically

So for my work I receive plans from architects, and then I need to clean these plans up and put them into our layerstructure.

This means, since a building always has around 20+ floors, I start out with making a list with all the layers that are originally on the plan, and to what layers I need to convert them...

Since english aint my motherlanguage and i don't know if I explained it properly, a short example:

Architect Our layer structure

A1_4217--_E- Wall

A1_423---_ E- Floor

A1_47----_E- Window

A1_479---_E- Door

Since this is the same for every floor of that particular building, and the list of layers is always HUGE, I would like to know if I could make a command where i define wich layers need to be changed into what other layers, and this way I could automate this process so I can make this silly task less timeconsuming...

Any input would be greatly appreciated, thanks in advance...

Have you looked into LAYTRANS, and creating a template file (.dwt) ?

Have you looked into LAYTRANS, and creating a template file (.dwt) ?

I have worked with autoca for a few years now, and i never used or knew about this function before

Thanks a lot for your help, exactly what I was looking for...

In the same manual about laytrans I found out about laydel, but I also found out this only works with versions Acad 2007+.

Any idea if theres a similar function for the 2002 version?
