The Fit/Meas Options button brings up a dialog where you can specify a series of options related to arm measurement and geometry fitting.
Startup In Meas Mode. Check this option and choose a measurement mode to have the interface automatically enter a specific measurement mode after being started.
Lock Circle Radii to. Check this option and enter a radius to lock the resulting circle from a circle fit to a specific radius.
Lock Sphere Radii to. Check this option and enter a radius to lock the resulting sphere from a sphere fit to a specific radius.
Temporal. When in Stream Points mode, points will be record- ed at the rate specified under the Arm Settings in the Query Rate During Measurements field. Note that due to hardware, network, and other limitations, the rate will not match the re- quested rate exactly.
Spatial. When in Stream Points mode, points will be recorded spaced by the specified increment. Note that due to hardware, network, and other limitations, the spacing will not match the requested increment exactly.
‘Good’ Threshold. Set the default radius for measurements to be considered “good” (in the “green zone”).
Working Field Threshold. Set the default radius in which the mode begins zooming and emitting an audio cue.
Acquire X Samples per Point. Specify the number of samples that will be averaged to produce the resulting measured point while in Average Discrete Points mode.
This section of the Fit/Scan Options dialog is important for controlling line scanner data .
Send Cloud Data to SA Every [X] Seconds. Point cloud data acquired from scanners is sent to SA in batches. This option allows you to control how frequently those cloud point batches are sent to SA.
Auto Increment Cloud Name. When selected, upon completion of a scan, the point cloud name will automatically be incremented for the next set of scan data.
Use Scanner for Auto-Proximity Measurements. This check mark can be enabled in order to use the scanner for proximity triggered measurements. This can be a very fast way to measure points in specific locations.
Thinning Factor. This setting is applied in addition to the manufacturer’s thinning settings in order to determine what portion of the scanned points are actually sent to SA. For example, if the manufacturer’s settings are set to send every 2nd point, and the setting here is to send every 2nd point, then SA will receive every 4th point.
Min Angle Filter. This is a more advance filter option that con- siders the curvature of a scan line. This provide a means to keep data on transition and edges while filtering out excess data on flat, featureless regions. It offers two controls a Minimum Angle in degrees to define the flat regions and a Max distance value which ensures that points are returned within this maximum threshold. This ensures some data is returned on wide flat expanses.
Edge Line (eg sheet metal). This option is used for measuring an edge, typically of a thin plate (such as sheet metal) when in Line measurement mode. For this mode, you first define the plane of the flat surface whose edge you’d like to measure. Then, start measuring and slowly drag the probe tip along the surface until it begins to fall off the edge. This will define one end of the line. Repeat on the other end of the edge, and a line will be created. It is important to move the probe tip very slow- ly (depending on the measurement query rate) and to ensure that the probe remains in contact with the surface at all times.
Probe Center. When in Line measurement mode, the line is fit to the probe center points.
Set Triggers. This is equivalent to right-clicking on the Geometry Trigger measurement mode button, and allows you to define geometry triggers.
