Topic: Flex Duct Creator

[ramonportes]

I"ve been using this routine since ACAD 2012 with no issues. Recently I upgraded to AutoCAD 2015 and lisp is not working anymore. It returns the following error:

uct diameter is set to 16.0
Select center line of flex duct.[Diameter]<16.0> Enter to quit.Backtrace:
[0.48] (VL-BT)
[1.44] (*ERROR* "bad function: VLAX-CURVE-GETPOINTATPARAM")

:CALLBACK-ENTRY.6 (:CALLBACK-ENTRY)
:ARQ-SUBR-CALLBACK.3 (nil 0)

Any idea?

It may not be ACAD2015 but how far the geometry is from the origin.
The Curve functions do not play well when too far from 0,0,0.
So try creating the duct near 0,0,0 and see if you get the same error.

Also are you using version 2.2?

[ramonportes]

Thanks for your quick answer. I was not using version 2.2, but 2.0. I tried near to 0,0,0 and received the same error.

I think is related to AutoCAD 2015 because I was reading an article the other day informing developers that Lisp functions and command call routines were changed in ACAD 2015.

Are you able to provide a link to that article ??

I thought that may have been the one.
Kean is discussing the consequences of making fibres inactive, and how that affects Commands. I doubt if that would affect the VisualLisp COM function calls.
I'll ask Kean to comment on this.

The functions are in the help document. Not that that is proof of anything.

It's late here so tomorrow I will add some debug code to the routine to see if we can narrow down the cause of the error.
That is if it's in the routine and not ACAD2015..

Good night

[ramonportes]

I was trying to help by pointing out it may be an ACAD 2015 issue. The real fact is that I have no clue of programming and would like to use the flex duct lisp in some drawings I need to do. I will try tomorrow or Sunday to try with a friend computer with ACAD 2014 and will notify the results.

Thanks again CAB for your routine and your assistance, good night.

I tried the routine in 2015
This was with metric units set.

Missing (vl-load-com) perhaps?

I checked that too Owen, It's the first line in the source

I can't see how this relates to the removal of fibers. If someone can post the steps to reproduce the problem I can ask someone to take a look, however.

Quick look at the code and the (command "._select" "Au" does not work for me in ACAD2006.
Also  a Break command in there but that's it. No Vlax stuff in there.
Maybe the command calls changed the prompt order or options.

As far as the vlax-curve problem I would try Repair or Reinstall Autocad to see if that fixed the problem.
