Pointcloud Operator dialog box - POINT COLORMAP Operator
The POINT COLORMAP operation evaluates the deviations of the data points contained in a COP command compared to a CAD object. The deviations can be represented by colored dots, colored needles showing the actual deviations or the numerical value of the deviations. The plus and minus tolerance, the size of the dots, the scale to be used for the needles, and the initial manual alignment need to be specified.
To apply the POINT COLORMAP operation to a pointcloud, click Pointcloud Point Colormap () on the Pointcloud toolbar, or select Insert | Pointcloud | Point Colormap.
The recommended process when creating a point colormap is:
The data is cleaned or selected on the surface where the point colormap is needed.
Use the DISTANCE type setting from the Filter COP Operator to filter the data.
Create the point colormap.
Example of the recommended steps to apply a point colormap
The Point Colormap operator has these properties:
Tolerances - Used to set the upper (plus) and lower (minus) tolerance values:
Plus - The upper tolerance value
Minus - The lower tolerance value
Use dimension color scale check box - When you select this check box, the software defines the color bar used for the Point Colormap color properties by the Dimensions Color Bar. For details on the Dimensions Color Bar, see "Using the Dimensions Colors Window (Dimensions Color Bar)" in the "Using Other Windows, Editors, and Tools" chapter of the PC-DMIS Core documentation.
Edit Color Bar - When the Use dimension color
scale check box is not selected, the Edit Color
Scale button is enabled. When clicked, the functionality to dynamically
change the color, scale and threshold of the surface and point colormap
properties becomes available through the Color Scale
Editor dialog box. For details, see the "Edit
the Color Scale" topic.
Dots - Colored dots
Size - Size of the dots
Needles - The scaled deviation (using the Scale value below) as a colored line segment normal to CAD
Scale - Scale value to be used for the needle representation
Text - The numerical value of the deviation
Max distance - This value only allows points that fall within the max distance to be included in the colormap. Note that if this value is too small, you may not see all the expected colored deviations. A good rule of thumb is to set this value slightly larger (10%, for example) than the largest deviation.
Thickness - This allows you to add a thickness value to deviations on the colormap. This is useful if you want to add a material thickness to a CAD surface model.
Click Create to insert a COP/OPER,POINT COLORMAP command into the Edit window.
For example:
COPPCOLMAP1=COP/OPER,POINT COLORMAP,PLUS TOLERANCE=0.0394,MINUS TOLERANCE=-0.0394,THICKNESS=0,
SHOW DOTS=YES,DOT SIZE=0.0787,SHOW NEEDLES=YES,NEEDLE SCALE=10,SHOW LABELS=YES,
SIZE=50023
