Have you installed a pdf printer on your PC?

ah, my message was too long. I understand The most important thing is the base so: do you have a good course, tutorial or book to recommend for a beginner? Thank you for you help! No book/tutorial.... just 40+ years working with CAD. I used to teach in one of my past jobs, but nolonger, disscarded ...

Ok, I'll try.
One question at a time, what do you want/need?

I am having issues with the code below, in that if the kayer 'Insulation' does not exist the layer is created and everyting works fine. However If the layer exists everything executes as expected, but at the end the (CD_SHAPE) is exucuting a second time?? . ; Create Insulation Layer + layer attribut...

I think I've craked it:

Changed this: to this: Now working as expected

Sorry Quan, but your change has not improved things :( I'm trying to create a section of Rectangular ductwork, complete with flanges at both ends. In some cases the user will require insulation and in others they will not. So by filtering via the External Insulation Thickness (eit), I want to either...

Thanks Quan,
However if I add the '(' as you suggest I am missing the closing ')' ??

edit:
scrap that, I just noticed the ' ) ; end (/= eit 0)'

Having trouble setting a cond statement. When the value of 'eit' is anything above '0' I want to create the insulation entities. [within the (progn....)] If 'eit' is zero I want to skip this step and go to (INS_MB) The following code does not work & I can't see my error(s) (defun DRAW_INS () ;--...

This is where the codes is atm. I've also added a check for the layer existance. (defun MKLAY_INS ( / ) (if (tblsearch "layer" "Insulation") (DRAW_CD) (progn (regapp "accmtransparency") (entmakex (list (cons 0 "LAYER") ;defines create new layer (cons 100 "...

Hi Quan, Thanks for the code. I had to go to the thread you kinked to as part of your code failed. It errored here : LM:trans->dxf copied this and all is good now :) (defun LM:trans->dxf ( x ) (logior (fix (* 2.55 (- 100 x))) 33554432) ) . Most of your code I understand, but this confuses me, can yo...

Hi Quan, Happy New Year :) :) Thanks for the link, sadly that went way over my head :( I am creating a new layer & setting it's attributes This is where I am so far: (entmakex (list (cons 0 "LAYER") ;defines create new layer (cons 100 "AcDbSymbolTableRecord") (cons 100 "...

Anyone know how to set the layer transpaarency in lsp??
Ihave tried exporting a file to dxf to find the code but the dxf files are not as they used to be

Regardless of dongles or other license types I think perpetual license means "perpetual" if you buy a software you have the right to install a re-install it as needed , they need to put an online alternative to deactivate or link the license to the PC as Microsoft has done when you buy Wi...

Thanks Quan, you are a star
