error: autocad variable setting rejected "clayer" "0-wndr"

HAS140 — Wed, 28 Nov 2018 20:23:51 GMT

Im receiving the above referenced error on a lisp routine, which up until now, I have never experienced. Its a routine to insert doors into a drawing. The routine previously allowed doors to be inserted on any layer named *-wndr. (see attached pic of dialog box generated by the lisp, note the message at the top of the dialog box regarding "*-WNDR" layer) It will now only insert on "0-wndr" layer. If I go in the code and rename "wndr" (toward the bottom of the script) the same error comes up with the new layer name I assign it, essentially looking for the '0". I don't know what changed (I did not make any edits to the routine). Here is the code.

Thank you in advance.

Here is the code:

I'm trying to step through your code to find out what the error is, can you provide all the parts and pieces so that I can successfully run the code? when I call the DR command, I'm getting a message:

user cancelled dialognil

Thank you! I have attached a zip file containing what I believe is to be all off the necessary files.

stepping through makes it a whole lot easier. You are setting the current layer to a layer that does not exist within the file you are working in. You should modify your program to check to see if the layer exists prior to setting it current, and if not, create the layer.

Re: error: autocad variable setting rejected "clayer" "0-wndr&

HAS140 — Wed, 28 Nov 2018 21:04:17 GMT

if I understand you correctly, you are suggesting that the "0-wndr" layer is non-existent and/or not current?

Before I had this issue, the lisp would insert the door on my A-WNDR layer which is pre-set in my .dwt file and the layer did not have to be current. I don't know how this changed in the code, I didn't touch the script. So confused

chriscowgill7373 — Wed, 28 Nov 2018 21:16:02 GMT

The program calls to set the A-WNDR layer current, it doesnt matter what the current layer is when you start the program, if the A-WNDR layer does not exist in the file, then it cant set it current, which is the reason for the error message. Did your template file change in the new version?

HAS140 — Wed, 28 Nov 2018 21:27:11 GMT

Do you mean the program calls to set it to 0-WNDR layer? It's not going on to my A-WNDR layer that is preset in my dwg. This is my issue. Where in the script is saying this? As I stated earlier, prior to this problem the door would be placed on any layer ending in *-WNDR and now it's forcing it to go on 0-WNDR... can you see anywhere in the script where it can be changed not look for the 0 to be in the layer?

Re: error: autocad variable setting rejected "clayer" "0-wndr

chriscowgill7373 — Wed, 28 Nov 2018 21:41:17 GMT

Your program determines the layer of the wall you select

It then strips out the rest of the name, except for the first character

It then combines that first character with the WNDR

It then sets that layer current

It then inserts the door block

It then resets all the variables back to their default values.

There is no provision for if the layer does not exist.

If the wall you select is on a layer called 0 or 0-WALL the layer the program is going to look for is going to be 0-WNDR

If that layer does not exist, your program will fail.

So, in your test file, what layer is your wall on?

In my file the wall is on A-WALL

The program strips it down to A

Then adds A-WNDR

I'm using the default template with no layers established

I error out with "error: autocad variable setting rejected "clayer" "A-wndr"

If I add the A-WNDR to my file, it works as designed

Short of having inadequate error checking in the program, the program works as it should.

HAS140 — Wed, 28 Nov 2018 21:50:11 GMT

Now, that makes sense! Thank you so much for that clarification. And of course thank you for taking the time to look at this. I greatly appreciate that. I originally was trying to insert a door on somebody else's drawing and we layer nomenclature wasn't my own which is when I experienced the initial error. I then tried it on a clean drawing but was trying it on walls created on the Zero layer. For my own drawings I have always inserted doors in walls on a-wall layers. I left my office so I will give it a try in the morning. Thank you again for your help!

No problem. I'll be around tomorrow when you get back in if you have any questions.

Re: error: autocad variable setting rejected "clayer" "0-wndr

HAS140 — Wed, 28 Nov 2018 22:13:11 GMT

Again, thank you for time. I'll let you know how it goes!

Re: error: autocad variable setting rejected "clayer" "0-wndr

HAS140 — Thu, 29 Nov 2018 13:57:40 GMT

yep. All is good. Thanks again. While I have you though, there is a slight issue with one door insertion. Cant get it to properly cut in a door in a wall in X axis, with the hinge side on the top left and swinging up toward the Y axis.

It cuts the door in with the hinge on the top left, but swings the door down toward the Y axis. All other doors work fine. I have attached a pic, see the door with the cloud. Can you see anything in the script that would cause this?

Re: error: autocad variable setting rejected "clayer" "0-wndr

chriscowgill7373 — Thu, 29 Nov 2018 15:18:55 GMT

can you provide your test drawing? that shows the door not working?
