Hard coding (I think?) Question...

Hello

CAD 2018R2 SP4.....

I have auto circles that all share the same centroid...I'd like to "construct" the points FROM these auto circles together to create ONE constructed circle.

I know about the "to points" option...but I don't want to use that. I was once shown a method where you measure the auto features..select the auto featres for construction...PC DMIS gives you an error message but will still put the invalid constructed feature in your edit window..then you type something like "numpnts.." It was called "hard coding" when it was shown to me.I was only exposed to it briefly & that was a long time ago..can someone help me out?

Please see code below.

Scan point vectors not normal to the surface

February 4, 2019, 6:30 am

Hello,

I`m trying to measure line profile of a feature. I`m using section scan to generate points from the cad (touch-trigger probe). So in the beginning of the scan everything looks fine but somewhere in the middle the tip does clearly not move perpendicular to surface when taking points. It gets so bad that the tip is basically "skiding" on the surface (at about 45 degrees angle). And it gets better in the end of the scan again.
I tried to use individual vectorpoints in tha same area (of the surface) and the situation is practicaly the same.
The results show that the profile is within 0.04 mm tolerance.
What could cause this? Any ideas?

BR,
Peter

I am working on a custom GUI that will run PC-DMIS. It is a simple (open program, run program, close program) interface designed to keep operators away from the code. I am developing in VB.NET. When it comes time to showing/printing the report, I take advantage of the OnEndExecution event and use the ReportWindow object method PrintReport. I am not seeing any report, even when I run PC-DMIS as Visible. Does anybody know how to force the report on the screen through scripting/VB.NET?

using .all from a scan to create a point.

February 4, 2019, 9:20 am

So, I have a scan (F23), which I'm trying to extract the point that equates to the max X value.
Code:
ASSIGN/V1=F23.HIT[MAXINDEX(F23.HIT[1..F23.NUMHITS].X)].XYZ
this works perfectly, with the .xyz suffix, but I want Theo's and vectors applied to a generic point.

looking at help file, they added .all to the assignment id for some reason, and of course applied .all to the end.
Code:
ASSIGN/V1.ALL=F23.HIT[MAXINDEX(F23.HIT[1..F23.NUMHITS].X)].ALL
if I push this into a generic feature, the results don't populate like I presume they should.
Code:
F26        =GENERIC/POINT,DEPENDENT,CARTESIAN,$
            NOM/XYZ,<V1.TX,V1.TY,V1.TZ>,$
            MEAS/XYZ,<V1.X,V1.Y,V1.Z>,$
            NOM/IJK,<V1.TI,V1.TJ,V1.TK>,$
            MEAS/IJK,<V1.I,V1.J,V1.K>
2018R1 SP5, if that may have a contribution here...

What am I doing wrong, to keep the .ALL from working in the generic?

Grouping Features Together

Anyone ever use "GROUPS?"
I sometimes have a lot of similar features that I would like to group together and collapse
so that my programs will be shorter.
needing to know how to get it to work.
I've typed in "Group" and tabbed over then at the end of what I'm wanting to group
I've also keyed in "EndGroup" and then chose "NO" on both for show all.
but It's not working.
Think I'm missing something simple here.

Nominal profile shift

February 5, 2019, 2:56 am

So I created two different scans (two individual areas of a "complex" surface) and out of those two scans I created a single "compound" scan with Cosntructed Set Feature (the aim is to create the common zone condition as per ISO 1101). The scans are all on one plane (section scan). I dimensioned the compound scan with Line Profile , first with Profile Only+ Use Best fit and then with Form and Location.
I thought that if you use Profile Only + Use Best Fit, then it will move (translate&rotate) the tolerance zone to best accomodate the points inside the zone. But. If now I create the Form and Loc additionaly, I can see that the black line that should represent the nominal profile frome the CAD, has also moved slightly ??? Why is that??? Why is everything moving.

BTW I`m using the prehistoric 3.7 MR3.

Scripting for 'to points'

Good Morning

I have several linear scans that I would like to break the hits out of into individual points. I was aware that there might be a script that was able to do this?

I have been searching on and off for a hour now and don't seem able to find it.

Does anybody out there know if this script still exists and if it does where might I be able to find it?

Thanks in Advance

Scanning along a IGES defined Curve

I'm working on a program that needs to follow a variable helix groove. The customer only provided a CAD file that contains a line defining the root of groove. It's contained in an IGES file. I don't have much experience with advanced scanning, and I'm having problems figuring out how to use this geometry to drive the scan.

Essentially what I'm looking for is to make a scan that follows the root profile of the groove and report profile of a line on the report.

Getting the alignment to their datums isn't an issue, as I've put their provided geometry into a solidworks model i've drawn from their print. Any help would be great.

Qualify long/thin probes on Global S

I'm setting up several project part programs here in Vietnam which was running on a ZEISS CMM with Q7 back home before.

I have big problems with long/thin probes, for example 3.5mm ball, 2mm shaft and around 100mm long.
Calibration itself is working, but when rechecking on the reference sphere it always give me an "Invalid reading of the measured point" error.
I tried lower the max. force and probing speed with only mixed results (very often still get that error).

I discovered that the weight balance may be off in Z -0.01 to -0.02 after 1-2 minutes after each probe change:

Click image for larger version Name: Probe_deflection.png Views: 20 Size: 126.5 KB ID: 443514
If I turn OFF/ON probing now manually it will reset weight balancing and the probes would work (until next change only).
The probe rack is also aligned 100% (~0.01 deviation between all of them).

Have anyone suggestions how to get this problem solved?

Here's my configuration:

Hexagon Global S 12.15.10
Controller Type „Common”
FirmwareId: FDC
FirmwareVersion: 14.01/14.02

ProbeHead MT5/HP-S-X5

I think I may have an addition to the "to points" script that was generously posted some time ago.
the one limitation that it had was in the case of features that had several layers of points like cylinders.

using the original script I added some code to pull in the layers as well as the number of hits.

' Extracts hits from features And creates vectorpoints With
