Adding number to a text string

I would like to create a routine to add the current dimscale variable to the end of text string.

Thanks

Derek

Would the dimscale need to be concurrent with the live dimscale? i.e will you need the text string to be updated to reflect changes to the dimscale value, automatically?

If you don't need it to be automatically updated you could just add a field that is assigned the value of the dimscale system variable.

Quick fix:

I will better describe my intent:

I am trying to automate the process of inserting a block and have it inserted on the correct layer, grab the correct scale factor (based on the current dimscale). Our layers are standard with a suffix for a particular scale.

The layer the block is inserted on is static, except for the scale suffix, (i.e. Layer-25, Layer-50) from drawing to drawing.

Ideally, if the layer does not exist I would like it to be created. Most likely the layer will exist in the drawing the block is being inserted into.

I was thinking that I could read the current dimscale and place it at the end of the layer name and make that layer current prior to inserting the block.

Thanks

Derek

Ok, I think I understand your intents, will see what I can do

Perhaps:

That was perfect...thanks a whole bunch!!!!

I suppose a reactor could be used also - hasn't got the error trapping standard of Davids though

Type "Ron" to turn on and "Roff" to turn off

Is there an advantage of error trapping?

Well, I just meant that David's LISP accounts for Locked, Frozen and Xref Dependent layers, whereas mine does not.

Using CLAYER with a frozen layer will give you an error:

Command:
LAYER ?/Make/Set/New/ON/OFF/Color/Ltype/Freeze/Thaw/LOck/Unlock: M

New current layer <3D>: 3D
?/Make/Set/New/ON/OFF/Color/Ltype/Freeze/Thaw/LOck/Unlock: S

New current layer <3D>: 0
?/Make/Set/New/ON/OFF/Color/Ltype/Freeze/Thaw/LOck/Unlock: F

Layer name(s) to Freeze: 3D
?/Make/Set/New/ON/OFF/Color/Ltype/Freeze/Thaw/LOck/Unlock:

Command: CLAYER

New value for CLAYER <"0">: 3D

Cannot set CLAYER to that value.
*Invalid*

Exactly my point

Thanks guys, I appreciate your assistance..
