Seeing that Lee has updated his "star" "rectangle" and "circle_tangents", I've changed my codes further more to be more user friendly with OSNAPs... One issue for Lee though "star" and "circle_tangents" can have ortho and polar modes - they aren't implemented, for "rectangle" IMHO I think it's not adequate... So here are my updates...

Just tested on A2014 and my "o" - osnap option doesn't work correctly, but on A2012 an lower versions it's just fine... Never mind, in A2014 - firstly set osnap combination and switch osnap with F3, or use single osnap with "e" - endpoint (for ex.) and so on...

I figured out what was the problem with A2014... It was my setting of OSNAP Dynamic Input menu... Should have turned off both checks for Dynamic Prompt...

So it all works as expected...

Here is my version of Lee's "star"... Of course all credits to mr. Lee Mac (I only composed it differently and added my ortho and polar subfunctions)

My version of myrec.lsp...

For circle_tangents I am not in it fully...

Good routine of grread. I want to study.

I know it's been while long ago when this was actual topic, but I wanted to share with you my new versions of Fibonuccie's golden spirals routines... Now I've tried to implement correctly tan and per OSNAP using my sub functions for obtaining list of points along curve from picked point in 3d space and I fairly did pretty well as you'll see if you check my lisps... I was using previous codes as starting point so Evgenyi's sub functions are there instead of Lee Mac's grsnap posted on his site... Still there are some issues you should avoid using this lisps :  avoid picking center point of circle and circle entity for searching per OSNAP as my sub function (per) implemented inside lisps may hang CAD; avoid picking collinear point and line entity to which start point is collinear for searching tan OSNAP as my sub function (tan) implemented inside lisps may hang CAD...

Related links with (per) and (tan) sub functions are posted here :

http://www.theswamp.org/index.php?topic=50364.msg555229#msg555229

So I'll post here first 4 lisps and next I'll post my last 2 versions - Fibonuccie's golden spiral... I know this isn't so much useful routines, but I like them and I hope someone may improve them to be even better... Autodesk has built-in algorithm with real OSNAP implementation so commands like LINE and so on are using correct per and tan snapping, but I think my versions are also good as for starting point and may serve to help someone to visualize that built OSNAP implementation is possible and through AutoLisp...

I hope you'll like new versions like you did like old ones... I have them both in my library and they serve me very well...

Hi mr. Lee Mac, recently I've played again with your and Evgeniy's grsnap functions and I have good news... I discovered that you can relatively simply implement dialog box with OSNAPS inside routines that are using grread grsnap...

Basically, you have to implement (setq osm (getvar 'osmode)) line just when (while) loop starts, and then add inside (cond)
this line :
(cond
  ( (and (= (car gr) 11) (or (= (cadr gr) 1000) (= (cadr gr) 2000)))
    (vl-cmdf "'_+DSETTINGS" "2")
  )
  ...
)
This way you ensure that when (while (setq gr (grread t)) ... ) loop starts you have super useful option ctrl/shift + right mouse click for bringing OSNAP dialog box where you can interactively check options you want and then continue with grread functionality...

To show all this I'll attach my recent revisions of some (grread) grsnap routines that may be of interest for studying... There are also your 3pt rectangle, star example and ctan.lsp with my intervention... So basically no need for user input by keyboard, but those may be left as additional option for those who like it (parsing base point to relative point is also useful and may be left for sure...)

Hi All,

I would like to include my GRLEAD lisp to the list of already sterling examples.
I originally asked lee-mac for such a program and then being the cheap-o I am decided to jump in and try myself.
I use it to program a flow waterjet.
I add lead ins and traverse lines to polylines within AutoCAD then export a DXF.
I ensure that all blocks (parts) are completely comprised of polylines (including circles (c2p/p2c lisp)).
I then reference edit one part and have it update all the others in the nest.
Once I have done all my parts and all paths are connected via traverse (green) lines I explode everything to just have lines and arcs.
I export to DXF and then bring it into flow cut where all green turns into traverse entities and all color 150 entities turn into 50% cut quality entities.

I am sure you all could code this way better, but heres my simple lisp   :-D

Cheers,
Brandon
