Auto Angle Point button
The Angle Point auto option enables you to define a point measurement that is the intersection of two measured lines. This measurement type allows you to measure the intersection of two lines without measuring the lines separately and constructing an intersection point. Six hits are needed to accurately measure an angle point.
To access the Angle Point option, select Insert | Feature | Auto | Point | Angle to open the Auto Feature dialog box for an Angle Point.
Auto Feature dialog box - Angle Point
With the dialog box open, use one of these methods to create the feature.
Using Surface Data on the Screen
To generate an angle point using surface data:
From the Graphic Modes
toolbar, click the Surface Mode icon (
).
Click once near (but not on) the angled edge in the Graphic Display window. PC-DMIS highlights the selected surface.
Verify that the correct surface has been selected.
The dialog box displays the value of the selected angle point and
vector once the point has been indicated. The direction of the surface
normal vector is determined by the side of the part that is accessible
to the probe. If both sides of the part are equally accessible, the
normal from the CAD data is used. The Flip Vector
icon (
) on the dialog box lets you change the direction
of the approach.
Click Create to insert the feature into the measurement routine. If additional mouse clicks are detected before you click the Create button, PC-DMIS overwrites the previous information with the new data. If an additional touch is necessary, click on the opposite surface of the angled edge.
Using Surface Data with the CMM
To generate an angle point using surface data with the CMM, touch once on each side of the angle edge. If the CAD angle point is not found, PC-DMIS displays the closest point and asks you to take the additional hits.
You should select the Find Noms option in the Mode list for this measurement method. For more information on nominals, see the "Mode List" topic in the PC-DMIS Core documentation.
Using Wireframe Data on the Screen
Wireframe CAD data also can be used to generate an angle point.
To generate the point:
Click once near (but not on) the angled edge. PC-DMIS highlights the selected surface.
Verify that the correct surface has been selected.
The dialog box displays the value of the selected angle point and
vector once the point has been indicated. The direction of the surface
normal vector is determined by the side of the part that is accessible
to the probe. If both sides of the part are equally accessible, the
normal from the CAD data is used. The Flip Vector
icon () on the dialog box lets you change the direction
of the approach.
Click Create to insert the feature into the measurement routine. If additional mouse clicks are detected before you click the Create button, PC-DMIS overwrites the previous information with the new data. If an additional touch is necessary, click on the opposite surface of the angled edge.
Using Wireframe Data with the CMM to Create the Feature
To generate an angle point using wireframe data with the CMM, touch once on each side of the angle edge. If the CAD angle point is not found, PC-DMIS displays the closest point and asks you to take the additional hits.
You should select the Find Noms option in the Mode list for this measurement method. For more information on nominals, see the "Mode List" topic in the PC-DMIS Core documentation.
Without Using CAD Data
If the angle point is to be generated without the use of CAD data, touch three times on each surface to find the two planes. The displayed angle point is at the first hit location.
Typing the Data
This method allows you to type the desired X, Y, Z, I, J, K values for the angle point.
Type the desired X, Y, Z, I, J, K values for the feature into the dialog box.
Click Create to insert the feature into your measurement routine.
