DXF Codes for Dim and Text Styles

When I do this

(entget (tblobjname "DIMSTYLE" "D12"))

I get a list with about 12 of the DXF codes for the dimstyle "D12" in this drawing. But we all know there are many more DXF codes for a dimstyle. I can't seem to find any reference for these except the common DXF section. Same issue for the TextStyles I'm working with.

It may be easier to do with vl if you dump a single dim you get access to all the variables some 40+ and you can change any of them.

Nice one as usual Lee, only advantage in the VL is it uses lables it may still be confusing what number refers to what.

Thanks again all. I have run into one more issue with the dimension properties. Remember, these are placed on the fly, no user input or selection allowed. So I could use either entmake or just draw the dimension using command and then setting some properties for it as (entlast) or a variable I've assigned to it temporarily. But I'm stumped on how to format the text in a few dimensions due to space limitations. The image on the left is what I end up with by just drawing the dimension like this:

(command "._DIMLINEAR" pt1 pt2 "V" pt3 "")

But what I want is what is shown in the image on the right. I think I need to change the property "Text Inside" but not sure how to do this.

Just did the simple -dimstyle and got everything.

Just do say (command "DIMTXT" 3.5) etc before your line not sure which DIM Var is the one you want so do as below 1st then change the dimstyle and do again. Almost forgot you may need 0 or 1 for on/off

Good Day BIGAL. I think I found it by using the variable "DIMTIX" like this:

(setvar "DIMTIX" 0)
 (command "._DIMLINEAR" (polar (polar gp4 a270 (+ offsetdimV afrmdp1 1.75)) pi 1.4375)
   		 (polar (polar gp4 a270 (+ offsetdimV afrmdp1)) pi afrmwd)
   		 "V" (polar gp4 pi 9) "")
 (command "._DIMLINEAR" (polar (polar gp3 a270 (+ offsetdimV afrmdp1)) 0 afrmwd)
   		 (polar (polar gp3 a270 (+ offsetdimV afrmdp1 0.75)) 0 1.4375) "V" (polar gp3 0 4) "")
 (setvar "DIMTIX" 1)

The dimensions don't quite end up like I really want but at least I can set the smaller ones outside of the extension lines.

Just ran into one more thing with this issue. I can not control which dimensions are written outside of the extension lines but I need the text to be on the other side of the arrows. I know a lot of this depends on which dimension point gets picked first but the text still ends up on the opposite side of where I want it. See example below. The sketch on the left shows how the LISP code draws the dimension, the sketch on the right shows what I need it to end up looking like. I'm searching through that long list of DIMSTYLE variables and don't seem to find the one for that particular setting.

UPDATE: OKAY, many thanks again you guys. I found by playing around with the DIMJUST variable, this too can be controlled, on the fly.
