I think that bug has been resolved.  Update to the latest 11.0.16 version of PolyWorks and you should be good to go.

If you are still looking for measurements on your threads, I know of a way to do it in IMInspect... Shoot me a message and I will follow up with you!

I got the arm running on my new 64-bit Windows 7 machine.  I got a .dll directly from Romer in March, but I think its all officially released now.  Someone else trying to run the arm on 64-bit has told me it is unstable and has connection problems, but I did not see that with my system.  64-bit is nice because when you are running the scanner on the arm, you can take way more points.

I've used Norton Antivirus, Avast, and ZoneAlarm and never had an issue like that...  ZoneAlarm used to ask me to whitelist the various modules the first time I ran them, but otherwise no problems.

Hi,

I think this is pretty straightforward...

1. scan everything you can in IMAlign.  Mesh it, or not.
2. Open IMInspect and import your CAD model
3. import your polygonal model or IMAlign project as the Data object
4. Probe the hidden surfaces as planes.  You can probe a lot of points to get better coverage (like 50 if you want).  Make sure to compensate correctly so that the data points are compensated.
5. Select all the elements from the probing session(s) and Edit > Data Reference Element > Ignore for Alignment
6. Do your Best-Fit alignment, which will drag all the Data objects (polygonal model, probed points) and their associated features (the plane primitives) along.
7. Run your Data to Reference comparison, and your probed points will act just like the vertices in your polygonal file, giving you a good surface analysis
8.  If you want more coverage of the plane areas at this point, just resume probing- you should be "in position" at this point.  Do Stationary, or Continuous Time or Distance probing to get good coverage, MAKING SURE THAT YOU HAVE "Compensation" checked in the probing dialog zone, and that you are compensating to the CAD object.

If you really want to compare the plane FEATURES with the CAD, you'll extract the nominal planes at this point, and use the Feature Controls to set up either GD&T like Flatness, or simple dimensions like XY angle or whatever.

Hope this helps!

Morphing is available as part of the Advanced Manufacturing Module add-on for IMEdit.  It sounds like you may not have the license.   :(

As far as I know the only way to update report tables in your report is to actually define the table and the destination in the report.  As you know, for snapshots all you have to do is update them all!  For tables, you will need to first get the name of the table from your report items, then specify the table in the report where you want it inserted.

FORMATTED_REPORT ASSIGN_ITEM ( "Section 1 radius results", "report 1", "table 5" )

where "Section 1 radius results" is the name of the table in the Report Items
and "table 5" is the table location in the existing report.

Hi guys,

I'm able to use my Space Navigator fine as of V11.0.6...  Hope everyone else is able to as well.

There are a lot more settings for importing spherical datasets than for "normal" datasets!  Make sure your PolyWorks version is the most current patch, as some changes have been made recently.

I have a nice flash video that explains most of the settings, called "Import Spherical Dataset", which comes in the Survey Learning Guide.  The Survey Learning Guide can be downloaded from
http://www.innovmetric.com/TechnicalSupportZone/MainTemplate.aspx?sectionId=5&params=id=3,cat=2,mode=list;
on the Technical Support Zone, under Tutorials > Surveying.

I can also email you the individual video.  Good luck!

Hi,

Do you have a particular point along the axis of the ring at which you must take the measurement?  If not, you can simply fit a cylinder primitive to your ring, then compare the polygonal model to the cylinder.  The data point with the most negative error will be the point at which you should place a caliper to measure across.  Alternatively, just fit a minimum cylinder to your polygonal model, which will give you the minimum diameter!

Yikes, what hardware are you using to try to capture the threads?  A CT scanner would have the easiest time capturing that detail.  Once you have the data, you can either compare the actual to the CAD (if you have it), or you can track the threads using feature tracking in IMEdit to get the entire thread...  If you post more details I may be able to help you more.  Good luck!

Hi Florian,

Do you mean, you want a grid where the gridlines are not equal distance?  Like 0, 1, 4, 8, 24... something like that?  Or do you just want a simple scale bar that can be used for scale instead of the grid?

If you want a scalebar, you could actually make a small scale bar from primitives (or use an outside program like Rhino), that you could import and place near your data along a system axis.  It's sort of a funny work-around, but I have done that in other programs.

I've seen that error before, but only when too few points have been probed.  Is it possible that the probe is not recording a couple of the points due to instability or something?

I personally use a Dell Precision M6300.  The Dells usually work fine.  However, for a less expensive, more customizable option, you might try Sager.

They specialize in notebooks, they are less expensive, and they have tons of options.  I've used a few Sagers and never had a problem.

Wow- the best possible way to close it would be to carefully re-scan that area until you get almost total coverage.  I don't know what scanner you are using, but try to point it directly at the sharp edge to get a few points on it.

If you still can't close the gap, I suggest a series of hole-filling procedures.  If there is any radius at all to the edge, you can probably use gap filling, partial hole-filling, and click-and-fill to close the gap.  My personal strategy would be to use gap filling periodically, then complete with click and fill.  Another possibility would be to use the Anchor Surface tool to build a nice bezier surface around the gap, then triangulate using that surface.

If you are trying to make it a very sharp edge, you can always track the sharp edge of the radius, then insert using the sharp edge curve.

Good luck!
