Aloha,
How do I create points along an arc at a specified distance?
I found the PTARC command but that creates points on the arc from a specified distance from first or the second point only.
For an example...I want points to be created on the arc...let say every 45 feet in between point 31 and point 32. See attached sample sketch. Is there a way to do this? (...with a "push of a button" without calculating each point from the first point;-) )
Mahalo!

I think the command is in the Cogo Pulldown Menu.
Interpolate points
Interval along entity
This is how I do it
Aloha, Jimmy: I tried just that...this is what I got...the points are not on the arc.
>points
>draw locate points
> screen pick
>snap to nearest
>snap point on arc at will
I'm using Carlson TakeOff in OEM Acad, so the command may not be in your survey app.
The command I see for your request is
"Interpolate Points >Interval along entity"
At command prompt type
PTINT
I'm using the ACAD embedded version, so this might not work for you, but
try typing DIVIDE, that does what you want.
another similar command is MEASURE.
This creates point entities, that you could snap a "real" point onto.
That is strange. I just tried RFB's suggestions, and it did not work for me. Unknown command.
Carlson Standalone 2008 with embedded Autocad
I'm using Carlson Survey 2013 w/embedded ACAD.
It's strange but I have seen commands that others don't have also.:-S
I have been told that the embedded Autocad versions have the AutoCAD Lite version of the program built in.
Maybe they have changed that.
Create a point at the center point and cogo the points in or draw polylines from radius to arc at constant angle right, auto add points.
I got it to work by:
1)converting the arc to a polyline
2)select "break" from the edit dropdown
3)select "polyline at specified distances"
4)enter distance along line. pay attention to the line direction
the only thing is that for, say 30' segments, you have to break at 30, 60, 90 etc.
then set points and re-join polyline if needed

Aloha, Jimmy:
You method actually works! I must be pretty tired when I tried your suggestion...I chose the wrong command!
Thank you!

Aloha, Pin Cushion:
Thanks! This works; however, I was hoping for something a bit more automized. 🙂

Aloha, Rick:
I tried the "divide" command that also worked. Once divided I selected them all and use the "create points from entities"
Thanks!

Aloha, Lee:
Thanks to you and everyone for chiming in! Now I have more than one method to do this!!:good: :beer: 🙂
Glad to help!
I know you have gotten your question answered, and there are probably several ways to attack it, but if you are going to calculate points on an arc/curve, you should probably create a radius point also. Might help, and it certainly couldn't hurt.

Aloha, Carl:
Thank you so much for the suggestion. Will definitely do this. I just learned yesterday...having the radius point helps a lot when I wanted to layout a curve with my Survey Pro field software. Of course I can lookup on the drawing I made to enter the radius value. But with the R point created I can simply "push the button.":-)
Thanks again for your input!
