Very much appreciate you taking the time to have a look.

Your analysis was correct - what I'm trying to do.

I'm sorry you can't open the file ... essentially it contained the two closed sections small one and then the other larger which ends up a thrie beam (three high rolls and two valleys).
I've run out of time and had to compromise the presentation as I wanted it all 3d.

There's gotta be a way. I'll have crack utilizing your suggestion.
And persevere...
if I get something I can consider success I'll post it here might help someone else. ]]> Wed, 07 Oct 2026 15:53:19 +0000 https://www.cadforum.cz/forum_en/forum_posts.asp?TID=14815&PID=40409&title=loft-issue#40409 <![CDATA[AutoCAD : Loft issue]]> https://www.cadforum.cz/forum_en/forum_posts.asp?TID=14815&PID=40408&title=loft-issue#40408 Author: philippe JOSEPH

Hello 2jimB, what I see is a road guard rail, correct ?

B001 should be like a rounded W.

B012 should be like a double rounded W.

B007 should your transition beam between those elements B001 and B012.

On the left side of B007 there is already the Ronded W but begining at approx. 1/3 of the 2 m transition it will become the double rounded W.

I'm afraid that AutoCAD will not LOFT easily a 3D surface between those 2 W shapes.

You will have to simplify the 3 D surfaces or do the first 1/3 like a loft ( or SWEEP ) between a little W and a bigger W and then LOFT an other double W shape to the big final double W.

I will try on my side but I'm not able to open the AutoCAD file Loft_--.dwg now.

Eventually, see the related tip N° 7267 accessible here under.

I'm trying to loft two closed but different shapes.
Been trying all day I cant do.
Its for a tender I want to present a concept.
I've attached a pic of the transition beam 2mts long between the two elements.
The attached pic is from gov site but they will not provide cads to prevent tampering of their drawings.
The cad is attached.uploads/213831/Loft_--.dwg
Anyone be able to help be very much appreciated.

give e some advice be very much appreciated. ]]> Wed, 07 Oct 2026 10:35:30 +0000 https://www.cadforum.cz/forum_en/forum_posts.asp?TID=14815&PID=40407&title=loft-issue#40407 <![CDATA[AutoCAD : Amazing Lisp for drawing stairs]]> https://www.cadforum.cz/forum_en/forum_posts.asp?TID=14812&PID=40402&title=amazing-lisp-for-drawing-stairs#40402 Author: nameci

StairSec.lsp

Although this is a very good lisp routine, I can not take the credit for it, below is the author and where I got it from.

If anyone wants to try it, load the lisp, enter stairsec at the command line, and follow the prompts.

Enjoy,

Hi All,

I have an amazing lisp routine for drawing stairs in AutoCAD Architecture (2d section). I wish I could upload the 2 screen shots I took which shows the lisp in action. You enter the command, pick bottom and top of stair elevation, then a pop up opens where you can pick the risers, treads overhang, rail ht., head ht, nosing, etc. Hit enter and it generates the stairs, railing, head ht., the data for the stairs.

Is there a way to upload the lisp here??

Thx,
