Can you create circle like this

Follow this instruction to create this;
1. create first circle at center point (0,0,0) and radius 5
2. create second circle at center (0,0,5) and radius 5
3. create third circle at center (0,0,2.5) with diameter (quadrant at circle
1 or (0,-5,0)) to (quadrant at circle 2 or (0,5,5)).
Don't use "rotate3d",I've got difficult to create this,anybody to help it.

Hi Walt,can you post to me "AutoCAD text window" file to create it,thanks.

 

Why not use rotate3d??

If I understand your post;
Build first two circles, then rotate UCS to:
origin 0,0,2.5,
X-axis to quadrant of circle 2,
and Y-axis @0,1,0
Draw 3rd circle using 0,0,0 for center & osnap qua circle 2.

 

Here it is:

Command: _circle Specify center point for circle or [3P/2P/Ttr (tan tan
radius)]: 0,0,0

Specify radius of circle or [Diameter]: 5

Follow this instruction to create this;

I mean,you don't use rotate3d for rotate circle no.3 (it's very
easy),because after you create line between quadrant (0,-5,0) to quadrant
(0,5,5),it have angle 26.57 degree,problem for me is, if I create circle
with angle,the circle can't create as a angle.


??????????????????????????????????????????????????????????????????????> Why
not use rotate3d??
