Contructing Generic Features

[Darrollh]

Good morning,
I don't use Generic features. however, I need to use them now. How do I go about setting one up? Thanks in advance.

[RIDER]

I prefer editing the feature in the command window, so I will click generic point, click ok, then key in my nominals in the code.

Basically, I need to make a circle out of a distance.

F1 =generic/point,dependent,cartesian,$

In the generic box select the circle then enter the data for the nominal and measured values but leave the measured diameter at zero hit create.

In the command window the feature F1 or what ever you have name it will appear. Edit the zero value with the data from the points if that is what you have used.

As an example if 2 points were used the measured diameter would be entered as PNT1.X.MEAS+(PNT2.X.MEAS*-1). The multiplication by -1 is use to get a positive number
from what ever point is returning a minus value.

[Darrollh]

Thank you. I’m going to do that. Thanks again!!

[UKCMM]

Should have added remember to add +0 to all the feature data except the measured diameter otherwise the generic feature will change position when run.

[marcc]

Let say your measured distance is called DIST1.
Create generic circle (Insert/Feature/Generic), give it name (let say CIR1), fill in nominal values.
ASSIGN/CIR1.DIAM=DIST1.MEAS

In this example, I have ONE point on each wall. I build them into a generic circle (SLOT_1) for the purpose of being able to show the tp of the center with basic.

Note the following:
-I am using TX, TY, TZ for the theo and X,Y,X for the actual.
-I have locked everything down with "*1"
-The output of the dist dimension set to NONE because all I using it for is to get the width value and feed that into my generic circle.
