VTube-LASER v2.7

Revision 2.7 Release Date: Not Released Back to VTube-LASER Back to VTube Software Updates (for LASER Mode)

NEW - BLM VGP 3D Bender Communications

BLM bender communications are now built into VTube-LASER. This protocol uses communications through a standard Ethernet connection. The protocol modifies YBC data inside BLM data files.

7 - NEW INNOVATION for Measuring Parts In Densely Packed Areas: DIAMETER CUT PLANES

Measure Across Several Diameters - VTube will find the correct straight

This new feature lets you scan across several diameters or objects of any kind - and still AUTOMATICALLY find only the diameter you want to keep.

AIM Inc. - Wirebending Applications

The feature was developed to solve a need that we encountered at AIM Inc. when measuring wire bent parts. The orange part shown below is a sample test piece that is formed from 0.2 inch diameter wire. When measuring this part the FARO scanner stripe often crosses four straights at the same time.

Illustration of the Issue

Imagine the HD (blue) laser stripe measuring one of these four straights. In order to measure one, it is very hard to orient the beam in a way that avoids the three straights you don't intend to measure. This is the easy way to measure one of these four straights:


However, touching four straights at the same time will not allow VTube to calculate a centerline of any one of these straights - unless you use the DCP feature. The DCP feature follows some simple rules to allow VTube to sort out and select the one straight that you intend to measure - every time.

It works great on tube assemblies too - like headers for multiple tubes close to each other, and HVAC assemblies where tubes pass close to objects like evaporators.

ENHANCED - Smarter Scanned Point Cloud Display for FAST Redraw Speed

Why This Feature Was Needed The issue is that VTube can handle extremely dense point clouds internally (in memory) - but graphics cards cannot keep up with the increased load from the new Bend Profile feature. So we changed VTube to automatically limit the number of points displayed on the screen. VTube was redesigned so that point clouds would be displayed densely enough (regardless of tube diameter), and fast enought (regardless of how many points are actually in memory). Goals for Calculation of Point Cloud Density for Display in VTube Goal 1: VTube needs to display points quickly on the screen. Goal 2: VTube needs to show an appropriate number of points based on the diameter being scanned.

How it Works In order to better anticipate how to draw dense point clouds, VTube has this new field in the System Options / Graphics Setup Tab. This new Diameter Factor value is multiplied against the current diameter to determine how close the displayed points should be on the screen. The default diameter factor value is 0.125. So, for example on a 2 inch OD tube, the points are displayed no closer than 0.25" on the screen. However, for a 0.25" OD tube, the point separation changes so that they display no closer than 0.031" (.25 x .125). It is Not Used in End Scans This feature has no impact on END SCANS. End scan point clouds are always display no closer than 0.005" (.12 mm) - regardless of the diameter.

Debug v2.6 Build 126

• Build 125 did not use DCP for the OUT DIAMETER measure processes. (DCP always worked in the Tube Measure - Cylinder process worked.) This is corrected in Build 126.

Debug v2.6 Build 127

• We fixed the Cut Plane measure dialog so that it changes point numbers when you move to the next point.
• VTube automatically switches the new cut plane to ACTIVE - but didn't update the checkbox in the model menu on the right with a check. This has been corrected.

Changes v2.6 Build 130

• We changed the report template engine so that it can handle extra spaces in tag fields.
• We added the "Stay On Top" checkbox option to the Report window. This value is saved in the persistent configuration file.
