Points from a circle?

[qualineer]

Is there a way to get the points from an Auto Circle?

[brian.freeman]

 cir1.hit[1].tx, cir1.hit[1].ty,cir1.hit[1].tz

 cir1.hit[1].x, cir1.hit[1].y,cir1.hit[1].z

Just pick the points (number) and plug them in to the [#].
Do this for each point you want to 'pull' from the circle.

[louisd]

or you can assign an array of hits and go from there.

ASSIGN/V2 = SCAN1.HIT[1..SCAN1.NUMHITS].XYZ

Hit F1 and click on "Search" tab. Type in "Hit Arrays" for detailed info.

I am not sure about the earlier versions or I could be way off base but, I clicked something in setting in 2019 and I was able to see and extract the points I needed without any additional coding.

[anthony.alfaro]

Darroll is correct. with the later versions of PCD you can do a constructed point an select individual hits from a circle feature (or any other feature for that matter.)

[mdobb829]

 cir1.hit[1].tx, cir1.hit[1].ty,cir1.hit[1].tz

 cir1.hit[1].x, cir1.hit[1].y,cir1.hit[1].z

Just pick the points (number) and plug them in to the [#].
Do this for each point you want to 'pull' from the circle.

You have to create each point as a GENERIC POINT. You also need to leave the labels for each circle as CIR1, CIR2 and so on. When constructing generic features you need to leave things in the PC-DMIS syntax. Here is a sample code from a (4) Point circle;

F1         =GENERIC/POINT,DEPENDENT,CARTESIAN,$
            NOM/XYZ,<CIR1.HIT[1].TX,CIR1.HIT[1].TY,CIR1.HIT[1].TZ>,$
            MEAS/XYZ,<CIR1.HIT[1].X,CIR1.HIT[1].Y,CIR1.HIT[1].Z>,$
            NOM/IJK,<0,0,1>,$
            MEAS/IJK,<0,0,1>
F2         =GENERIC/POINT,DEPENDENT,CARTESIAN,$
            NOM/XYZ,<CIR1.HIT[2].TX,CIR1.HIT[2].TY,CIR1.HIT[2].TZ>,$
            MEAS/XYZ,<CIR1.HIT[2].X,CIR1.HIT[2].Y,CIR1.HIT[2].Z>,$
            NOM/IJK,<0,0,1>,$
            MEAS/IJK,<0,0,1>
F3         =GENERIC/POINT,DEPENDENT,CARTESIAN,$
            NOM/XYZ,<CIR1.HIT[3].TX,CIR1.HIT[3].TY,CIR1.HIT[3].TZ>,$
            MEAS/XYZ,<CIR1.HIT[3].X,CIR1.HIT[3].Y,CIR1.HIT[3].Z>,$
            NOM/IJK,<0,0,1>,$
            MEAS/IJK,<0,0,1>
F4         =GENERIC/POINT,DEPENDENT,CARTESIAN,$
            NOM/XYZ,<CIR1.HIT[4].TX,CIR1.HIT[4].TY,CIR1.HIT[4].TZ>,$
            MEAS/XYZ,<CIR1.HIT[4].X,CIR1.HIT[4].Y,CIR1.HIT[4].Z>,$
            NOM/IJK,<0,0,1>,$
            MEAS/IJK,<0,0,1>

You have to create each point as a GENERIC POINT...

That depends on what you want to do with them - you can for example dimension the location of a single hit just by changing the reference in the Edit Window

Original

Change to

DIM LOC3= LOCATION OF POINT CIR1[COLOR=#FFA500][B].HIT[3] [/B][/COLOR] UNITS=MM ,$
GRAPH=OFF  TEXT=OFF  MULT=10.00  OUTPUT=BOTH  HALF ANGLE=NO

There's also the CIR1.NUMHITS which can be quite useful.

[Griffin]

Alternatively, there's an option in AutoCircle called "To Points" which will create all the hits as individual point features. From there you could construct the circle.

[johnnyjohnson]

If you have already measured circle you can take the points out of it as a Construction Points (see picture below):
(It is in v.2018, I'm not sure if before also)
