understanding this...

ok guys im getting stuck on the tutorial like an idiot

 

i have the coding (attached and it says :- [CHECKING TEXT Example 2 drawing a beam further development more added.lsp loading...]

; error: malformed list on input

; Check done.

 

how do i find where this error is? because i cant seem to find it :/

 

thanks for all the resources and help, at the moment I'm just getting familiar with what the codes mean.. like osmode referring to snap point (that's correct right?) i hope so otherwise Im doomed

Example 2 drawing a beam further development more added.lsp

could it be that im loading it in to auto cad incorrectly? I'm doing it through autolisp then going to tools check text in editor and then it says that error... I'm currently going through the load autolisp files guide on the afralisp website.... the way i have been told to load a file is to type in APPLOAD then locate my file and then it tells me its loaded successfully. but then the code i just posted says "error malformed list on input... i seem to be more of a novice than i thought, i was up till late last night writing out the tutorial :/

This is wrong (setq oldblipmode (get "blispmode) 4 mistakes in it rather than me correct have a good look at it check your other code to compare

First, fix the code on the line indicated by BIGAL; you have 4 errors on that single line – check by comparing it with just the one above.

Second, may just remove at all the use of BLIPMODE system variable – is quite obsolete those days, and is set to 0 by default anyway.

 

There are errors too on those lines:

(setq p7 (polar p6 (dtr 270.0) (-hb nd)))
…
(setq p13 (polar p12 (dtr 90.0) (-hb nd)))
…
(setq p17 (polar p18 (dtr 90.0) wt))

I will let you discover those since will be better for your learning.

The above are errors that prevent the routine to draw, will your task to find and fix by yourself the result on screen.

 

Regarding the load of your routine – the APPLOAD solution is not wrong, but will be difficult to use while debugging. Is intended to load done routines for drafting usage.

I hope you are using the VLEditor to write your code – then just use the tools that it provides. You will find that there is a button to (1) load your code in AutoCAD, another one to (2) validate the syntax of the code and another one to (3) check the value of a variable – use those for beginning to debug your code.

that's brilliant guys thanks, I wasn't sure how to find where the errors were. http://www.afralisp.net/autolisp/tutorials/the-basics-part-4.php that's where im getting the above coding from. and i must have just copied that in correctly, so ill go back through it thanks

Now you are able to see the risks involved by writing a big piece of code instead of testing it in small units.

You have been pointed some syntax errors above, fix them and focus later to the remaining logical one (hope to figure it by yourself).

This is an excellent site to go to by the famous Lee Mac he has a tutorial on how to use Vlide and debug your code well worth reading www.lee-mac.com\tutorials.html#vlide

Thanks BIGAL though the link you posted appears to be broken, try this one: http://lee-mac.com/tutorials.html#vlide
