Jig with Multiple Entities

(1/2) > >>

SomeCallMeDave:
I would like to know if it is possible to 'jig' with multiple entities.  All the code that I have seen uses only a single entity for dragging.

I would like to be able to do something like image below (coded in LISP with grread and grdraw).

Can anyone point me in the right direction?

Thanks

Glenn R:
According to what I suspected and just looked up on ADN, EntityJig is for singles and DrawJig is for multiples. Also, you will have to override WorldDraw and 'draw' your entities (from a list of points you maintain internally) using the graphics device context passed into WorldDraw.

I've never had the need to do this, but if you get stuck, I'll have a go at it myself in the next couple of days.

Hope this helps.

Cheers,
Glenn.

SomeCallMeDave:
Thanks Glenn.   

I may not know how to do it, but at least I know it can be done.  :)

I will dig into DrawJig.

Thanks again

Glenn,
Thanks for the nudge in the right direction.  Using your suggestion and some sample code from Bobby Jones and Kean Walmsley I was able to get the circle and the text to  drag.  Next comes the lines (well, bed then the lines).

The code is just a proof of concept and is still very rough, but I would appreciate it if any of the experts could point out the major flaws and any pitfalls that I should be wary of.
