nan???

[RIDER]

So I wrote a new program today in 2019SP1 CAD++ using a model. I had a bunch of vector points that I used to construct a plane for datum A. One of the vector points was too close to a mag riser and caused the probe to false trigger. I stopped the program and moved the point 0.5" in the Y. All of the vector points were on a flat Z+ surface (0,0,1) vector. When the Do You Want to Update the Nominals of Related Features box popped up, I clicked No. After clicking no, I noticed that the theoretical xyz for everything that related to datum A, changed to (nan,nan,nan). It even showed up on the report as nan for the measured values of xactmeasure fcfs that referenced datum A!
My questions are:
Is this new for 2019?
What does it mean and or stand for?
Is it a bug?
Has anyone else experienced this behavior?

TIA for your feedback!!

NAN = Not A Number

or

NAN = No Aircraft Noise


Probably one of those two.

Indian bread..... Oh that's Naan! Lol

[bfire85]

Darrollh Ha!

[JEFMAN]

"Not a number" : the value doesn't exist (like SQRT(-1) for example, even if it's exist, but not in the real world)

[RIDER]

Is this a "new" feature? I have answered No to updating nominals before and have never had this happen. The weird thing is that the measured values remained unchanged (ie. actual numbers), but the theoreticals in the code and the measured values on the report showed nan. Is this going to happen every time I answer No?

[dph51]

“Imagine there’s no SQRT(-1), it’s easy if you try”

[Ego Murphy]

This is hilarious.

[JEFMAN]

Can you post the code ?
Are you sure that there's no text or non numeritical value in the features ?
What are the warnings in the F5 ?

[RIDER]

The only warnings on JEFMAN are 1. do you want to make this the default id? no. 2. do you want to quit without saving? yes.

[RIDER]

And here is the report.

[NinjaBadger]

Bug I guess.

What happens if you F9 the constructed feature and recreate?

[RIDER]

If I F9 the feature and click yes to update nominals, the nan goes away from the constructed plane theoreticals; however, it still remains on the report. I even F9ed the FCF and the nan remained. Haven't tried re-creating the FCF yet.

[Matthew D. Hoedeman]

Idea for ya for next time....

Instead of changing the THEO values to move the point, just change the TARGET values. It will touch at the target value without changing the THEO (or any of the THEO values for features down the list)

[JEFMAN]

I would create a feature set with the points, and then create the datum plane from it.

[Rich P]

could this be from Primary datum in constructed plane?

[SABarber]

Send prg and associated files to tech support for analysis.

[Ego Murphy]

could this be from Primary datum in constructed plane?

I was wondering the same thing.

Rider, PNT13 is missing from the list of ingredient features but the feature DATUM_PLANE is showing in it's place.

[JEFMAN]

PNT13 is the first point of the list, but the last in the datum list.

[AndersI]

PRIMARY_DATUM is the new name for the construction method TANGENT_PLANE. The next line is also a good indication of this (MATH_TYPE/CONSTRAINED_L2,BFRE)

[Ego Murphy]

Anders wrote,

Holy crap.
So... we may have a failure of the Tangent Plane w/ Constrained L2 math?

OP, switch to simple BRFE and see if you get ian instead of nan

"is a number"

[RIDER]

Yes. It only seems to happen when tangent plane is selected. Actual numbers show up in theoretical values when using BF and BFRE. The measured values of features that are dimensioned back to the datum plane still show nan in the report, even after F9ing the FCF.
