Any one have a good symetrical star in .dxf? I drew what I thought was correct multiple times. No luck.
Any help would be appreciated.

What size and how many points would you like.
Here's a real quick one I did.
Regards Terry.
That will work quite fine. Thank you.
Now, how do you draw a good star.
Well that one took about 3 seconds in Rhino.
I just chose (Polygon > Star > 5 points.)
Not much help unless your CAD has that feature.
Regards Terry.
Too quick for me Mr. Bean. I'll post mine anyway since my 5 pointer hasn't been gutted.
Here's a link to the geometry involved in regular pentagons & 5 pointed stars:
The Regular Pentagon (with 5 pointed star).

How about this one?

Somehow that one does not look like the Texas Ranger star/badge I am laying out for a guy. Cool none the less.
rcazwillis,
Just a word of caution. If you are replicating a Ranger badge you might want to check on the legalities. I had a friend (now dead) that was a big
E-bayer, and happened on a real Ranger badge at a gun show or flea market. He put it on E-bay and two days later he has a visitor at his door. It wasn't UPS either!

No greater love can a man have than this, that he give his life for a friend.
Mike,
Thanks for the word of caution. We are not actually replicating the badge. Just the shape, no words, in a sissy bar insert for a motor cycle. The guy is law enforcement and likes old badge styles. A JPG is attached.

Is that a "SpiroStar" from your spirograph?
Looks neat!
Yes, from the AutoCAD macro i threw together.

Wow Mr Bean, I never knew I had that feature in Rhino. Doh!
Here's how I used to do it (the hard way):
1. Decide the height of the star
2. Plot first point (pline) at 0,0
3. Second point is X=1/3 of height, Y=height
4. Third point is X=2/3 height, Y=0
5. Make a copy of this triangle
6. Rotate the figure:
Rhino: select the 1st point as rotation center, 3rd point as 1st reference and 2nd point as 2nd reference.
AutoCAD: select 1st point as base and 2nd point as reference.
The second leg of the triangle should be horizontal now.
7. Move the rotated figure from 1st point (0,0) and snap it to the other figure's 3rd point
8. Draw a line from the moved figure 3rd point to the other figure's 1st point.
9. Select all, trim centers and join, if desired

He he he. The polygon (star), tool in Rhino should cut down on time compared to your old method.
I seem to find new features in Rhino every time I use it.
