AutoCAD - Help drawing Curved Lines!!!

AutoCAD - Help drawing Curved Lines!!!

RE: AutoCAD - Help drawing Curved Lines!!!

Draw complete circles for much of the design.
Break the circles and then fillet them.  The
circular slot may be the most difficult.  
Sometimes when the bottom radius is full, the
fillet command does not work that well.
I think I would start by drawing the 2 inch radius
starting at 0,0 coordinates.  I would draw a line
from 0,-2 to 0,2 and then offset that line for
the different vertical lines.  Then draw a line
at -6,0 to 4,0 and then offset it to get the
horizontal centerlines or extremes.  I think I
would use 4 place decimal dimensions all places
to draw it and dimension it to whatever accuracy
you think is required.  The 3.000/3.010 would
be drawn to the mean of 3.005 plus or minus .005
inches unless your shop prefers some other way
of dimensioning this.  I also would cut the circles
in half about the the horizontal centerline before
filleting the circle and then mirroring at the end
about this centerline.

I'll have to try it this way..  Thanks for the input!!

RE: AutoCAD - Help drawing Curved Lines!!!

Draw one circle at 2" radius
Draw another at 5/8" radius 2 1/4" to the right of the first.
Draw a line through both circle centers and extend the line through bot circles.

Create a third circle usint TTR option, pick both the first two circles and use 5/8" for the radius.
