Layer Creater Lisp Routine Issue

Hello all,

I found this lisp rountine and it loads layers into AutoCad from a .csv file. It works great for the most part but I'm having touble when I use the "Freeze" column it hangs up. I'm posting the lisp & csv file. Just remember to change where the csv file is located in the lisp. Thanks for the help.

Are you trying to extract Layer list of a drawing to a .csv file ?

No. I'm going the other way. From the csv file to cadd.

Look into the open, while, read-line, and vla-put-* functions.

Works fine here in ACAD 2009

Autocad crashes when you invoke "Freeze" on the layer palette?

Ooops , now i know what you mean "Freeze column" , the column on the CSV file

So what exactly do you want to happen there anyway? you want some layers frozen upon loading?

It looks like he is using the CSV file to create layers and the layer settings/information. Sweet....

Yeah, I have the same issue, it hangs when I edit the freeze column in the csv file. Not sure why it does that. Hopefully someone will be able to figure this out. I would like to use this. I could also see a Thaw column. I like the fact that it will overwrite the exisitng layers in the file if they have been modified.

- If all you have is a hammer, everything looks like a nail.

Perhaps this will help (code written quickly):

Please note the changes made in the .CSV file attached (simply change the .TXT file extension to .CSV).

Hey RenderMan, Thanks for looking at this. But I'm not quite following you. Where am I suppose to put the .csv file path? Thanks

... I'm not quite following you. Where am I suppose to put the .csv file path? Thanks

This routine requires an argument (a file path) to a .CSV file in this case, which has the previously attached column format.

For example:

Say you were to save the .CSV file(s) in a directory on the server, we'll assume Z:\\my_layers_folder\\ (note that LISP requires double back-slashes), and let's also assume a file name of my_layers.csv, then you would use this to import the layers contained in said .CSV file:

(RM:CSV->Layers "Z:\\my_layers_folder\\my_layers.csv")

Basically, this permits you to specify any .CSV file (with the same format), and quickly import *those* layers. You could setup a macro for each discipline (assuming they use different layers), or one for each client... whatever. It really depends on how you work, and what your needs are.

If it would be helpful, I can easily revise the routine to be 'hard-coded' for you, if this is the only .CSV file you'd ever need.

Hope this helps!

Lee, Alan... having only skimmed them, *very* neat tools, guys (as usual)! :wink:

nice..........

Thanks - same to you

Thanks. It has its uses. Not nearly as versatile as your STEAL one, but I wrote this a while back and I only needed to bring in all layers. Speaking of, does the steal sub only allow for importing of named objects within a named collection, or will it import everything from a specified collection?

Only named items I am afraid - I suppose it could be tweaked to import everything, but having originally set the program up with DCL in mind, the structure is geared for a selection of named items from a collection.

But to be honest, I am slightly disappointed with the latest version of the 'Steal' program - having developed it to try to suit everyone's needs, I think I may have 'over-developed' it.

Sorry for my limited knowledge but I am missing something.

If I understand correctly...this is what I have at the head of the code:

(defun RM:CSV->Layers (path / f *error* extract trim activeDoc l
layerTable layerName layerItem layerDescription
layerColor layerLinetype layerLineweight
layerPlottable layerFreeze)
;; © RenderMan 2011, CADTutor.net
;; Exampe: (RM:CSV->Layers "Z:\\my_layers_folder\\my_layers.csv")
(RM:CSV->Layers "H:\\acad\\AutoCad Custom Support Folder\\Lisp Files\\ArchExist.csv")
(vl-load-com)
(if (and (findfile path)
(setq f (open path "r")))

Is this correct? If so....what do I need to type at the command line to get this to run? (I do have it loaded in Appload.)

Laugh if you must, as I do feal a little dumb here but.....I have to ask none-the-less.......lol

Put the call to the subroutine outside of the subroutine.

eg.

(defun _say (string) (princ "\nYou said: " string))

(_say "I like pizza.")

ummmmm......hummmm......errrrrr......\scratch....... what?.....can you repeat the stuff about BEER?
