Circular Lot Line
Circular Lot Line
(OP)
I am trying to draw a circular lot line. The radius is 50' and the L is 74.13'. Can someone help me with the command to draw this line. I can draw the circle, but can't figure out how to draw just the part I need.
Thank you.
Thank you.





RE: Circular Lot Line
If "L" is an arc distance, use the "arc" command, specifying the center at 0,0 and the start point at 50,0 and the length as 75.13. Then zoom extents to see your arc.
If "L" is something else, please post it.
RE: Circular Lot Line
draw circle with 50' radius, then break circle, leaving small arc, with 50' radius
then use LENGTHEN command, select arc, command prompts for options, use total, key in desired length, then select the end of arc you want to modify.
(experiment with LENGTHEN options)
this will give correct radius with desired length.
you will probably want this arc to be tangent to the bearing coming into it.
hope this helps

RE: Circular Lot Line
using start center and angle
type arc
0,50 (for start point)
C (for center)
0,0
A (for angle)
84.9467227
the angle is basically (74.13 times 180) divided by (pi
times the radius)
You could also create a lisp program to do this.
There is probably one all ready created somewhere
on the web.
You must have your units in decimal degrees
and to 7 places.

I think length refers to the chordal
length and not the circular length
as in this case.
RE: Circular Lot Line
If it is chordal, then you are right.
I assumed circular, because the other
method was a standard command option
of the arc command in ACAD.
