Measuring a Cone in Intervals.

[Darrollh]

Good afternoon,
How would I go about measuring a cone in Intervals? I know it's vague but I was asked to do this. I'm waiting on CAD and print.

One piece at a time. With pauses in between. Sorry, someone has to make the obvious jokes.

Assuming you mean a cone that has features cut into it then my first option would be to try using auto cone and adjust the hits to avoid cutouts, if that does not work use the constructed cone feature and take hits where needed

I would use autolines, than BFRE construct cone

Let's say you have some auto features that all share a centroid. And you want to construct them together to make one feature. PCDMIS will not let you construct them together because of the centroid (math invalid or whatever it cries about)....so instead you can do this (I'll show you an example with cones):

1) Measure each cone

MOVE/CLEARPLANE
CON2       =FEAT/CONTACT/CONE/DEFAULT,CARTESIAN,IN
            THEO/<0,0,0.4232>,<0,0,1>,60,0.045,0.688
            ACTL/<0,0,0.4232>,<0,0,1>,60,0.045,0.688
            TARG/<0,0,0.4232>,<0,0,1>
            START ANG=-42.5,END ANG=42.5
            ANGLE VEC=<1,0,0>
            SHOW FEATURE PARAMETERS=NO
            SHOW CONTACT PARAMETERS=NO
            MOVE/CLEARPLANE
CON3       =FEAT/CONTACT/CONE/DEFAULT,CARTESIAN,IN
            THEO/<0,0,0.4232>,<0,0,1>,60,0.045,0.688
            ACTL/<0,0,0.4232>,<0,0,1>,60,0.045,0.688
            TARG/<0,0,0.4232>,<0,0,1>
            START ANG=-42.5,END ANG=42.5
            ANGLE VEC=<0,1,0>
            SHOW FEATURE PARAMETERS=NO
            SHOW CONTACT PARAMETERS=NO
            MOVE/CLEARPLANE
CON4       =FEAT/CONTACT/CONE/DEFAULT,CARTESIAN,IN
            THEO/<0,0,0.4232>,<0,0,1>,60,0.045,0.688
            ACTL/<0,0,0.4232>,<0,0,1>,60,0.045,0.688
            TARG/<0,0,0.4232>,<0,0,1>
            START ANG=-42.5,END ANG=42.5
            ANGLE VEC=<-1,0,0>
            SHOW FEATURE PARAMETERS=NO
            SHOW CONTACT PARAMETERS=NO
            MOVE/CLEARPLANE
CON5       =FEAT/CONTACT/CONE/DEFAULT,CARTESIAN,IN
            THEO/<0,0,0.4232>,<0,0,1>,60,0.045,0.688
            ACTL/<0,0,0.4232>,<0,0,1>,60,0.045,0.688
            TARG/<0,0,0.4232>,<0,0,1>
            START ANG=-42.5,END ANG=42.5
            ANGLE VEC=<0,-1,0>
            SHOW FEATURE PARAMETERS=NO
            SHOW CONTACT PARAMETERS=NO

2) Construct them into a FEATURE SET. Just create the set and select the 4 cones press OK to get the code in your edit window. It will look like this-->

SCN1       =FEAT/SET,CARTESIAN
            THEO/<0,0,0.4232>,<0,0,1>
            ACTL/<0,0,0.4232>,<0,0,1>
            CONSTR/SET,BASIC,CON2,CON3,CON4,CON5,,

3) Once the code for the FEATURE SET is in the edit window....after each feature, type ".hit[1..10]". I typed 10 because each of my cones have 10 points and I want PCDMIS to use all ten points. If your cone has 47 points, or 90 points, or whatever, use that number if you want it to use all of the points. If your feature has 15 points and you type [1..7], PC DMIS will only use the first seven points of that cone when it creates the feature set. (hopefully that all made sense). As you add the ".hit[1..10]" after con2, con3, con4, and con5........ you'll see the nominal value of the feature set changing because PC DMIS is now recognizing that the feature set is being made out of the POINTS of the cones and not the CENTROIDS of the cones.
It will look like this:

SCN1       =FEAT/SET,CARTESIAN
            THEO/<0,0,0.4457>,<0,0,1>
            ACTL/<0,0,0.4457>,<0,0,1>
            CONSTR/SET,BASIC,CON2.HIT[1..10],CON3.HIT[1..10],CON4.HIT[1..10],CON5.HIT[1..10],,

4) Construct a CONE from the FEATURE SET. Use that cone for whatever you want.

SCN1       =FEAT/SET,CARTESIAN
            THEO/<0,0,0.4457>,<0,0,1>
            ACTL/<0,0,0.4457>,<0,0,1>
            CONSTR/SET,BASIC,CON2.HIT[1..10],CON3.HIT[1..10],CON4.HIT[1..10],CON5.HIT[1..10],,
CON1       =FEAT/CONE,CARTESIAN,IN,LENG,NO
            THEO/<0,0,-0.1727>,<0,0,1>,0.025,0.6995,0.7284
            ACTL/<0,0,-0.1727>,<0,0,1>,0.025,0.6995,0.7284
            CONSTR/CONE,BF,SCN1,,
