Hello,

Is there a way (a lisp?) to create e.g. pentacle basicly same way than a
circle is created? E.g. IŽd give the center point -> the program would ask
how many corners -> IŽd give 5 -> then IŽd just draw a circle but itŽd be a
pentacle.

?
thanks,
Pekka

What's wrong with the POLYGON command?

I recall seeing a LISP once that could draw stars and such. You might google

search it.

Perhaps, although dictionary.com says nothing about a circle being part of
it. I've seen many instances where posters use less than totally accurate
terms for something they're trying to achieve. In any case, unless it's
something he has to do over and over and over again, the POLYGON command is
a very good place to start. After that, all one would have to do is to
"connect the dots."

You can you use a POLYGON command.

Not sure why the others are going on about the POLYGON command, how that
creates a Pentacle `quickly' is beyond me.

BTW the ancient LISP routine you require is STAR.LSP which can be found at :

http://www.et.utt.ro/public/CAD/ACAD10/LSP/

These go back to the late 80's but still don't feature in current releases.

Download and add to one of your supported directories, type (load "star")
at the acad command prompt, enter no. of points (5), enter inner rad and
then outer rad.

Hope this helps.

Okay, what's the inner radius of a pentacle? Or more precise what is the
radius of a circle circumscribed about the interior pentagon formed by
connecting the vertices of a larger regular pentagon?

I wonder if that's in my pocket reference?

ThatŽs right!! IŽve been using AutoCAD for about 12 years and never have had
to use this command before...:-)

Thanks,

Where `R' is the distance from centre to point

s = length of flat on pentagon
r = radius from centre point to mid point of flat

R would equal the square route of (`s' squared over 4) + `r' squared


BTW the original poster wanted a Pentagon not a pentacle by the looks of
things ! Oh dear.

Well, as of this morning, the OP seems satisfied with the POLYGON command

I know. It can be very frustrating attempting to answer a question when the
OP doesn't know what to ask, or how to ask it accurately. I was lucky on
this one.
