You can use the Quick Scan functionality to create a quick scan on multiple polylines. The polylines can be open-ended or closed. For more information about quick scans, see "Creating Quick Scans".
To create a quick scan on multiple polylines, do the following:
In your Edit window, click to define where to insert the new feature.
Select Curve mode (Operation | Graphic Display Window | Change Curve/Surface Mode).
In the Graphic Display window, hover the pointer over the CAD element's first polyline and click on the part.
To select multiple polylines, press Ctrl and then click on each polyline.
The order in which you select the polylines is important. PC-DMIS generates the quick scan on the polylines in the order that you select them.
Make sure that the start points of subsequent polylines are accessible from the end of the scan of the previous polyline without collision.
Press Ctrl + Shift, and click on the start point on the polyline from which you want to start the scan. Drag the pointer along the polyline and in the direction of the scan.
Release the mouse button. PC-DMIS creates a scan and inserts it at the cursor position.
PC-DMIS generates the scan on the polylines in the order that you selected the polylines, starting from the point of the scan gesture.
After the end of the first polyline, PC-DMIS locates the nearest end of the next polyline. This end becomes the start end of the next polyline.
For tactile probes, the Jump Hole
check box on the Path Definition tab is always
selected. This is because the probe lifts between the scan on each polyline.
For spot laser probes, the Jump Hole check box
is available for selection, and PC-DMIS uses its last-used value. For
more information about the check box, see "Performing
a Linear Open Advanced Scan".
The Jump Hole check box is not used for laser
probes.
Selecting Multiple Polylines with the Quick Scan Gesture
You can also select multiple polylines along with the quick scan gesture. To do this:
Click on the first polyline.
Press Ctrl + Shift and then click on the start point on the first polyline from which you want to start the scan.
Drag the pointer along the polyline and in the direction of the scan.
Keep Ctrl + Shift pressed, and move the pointer over the subsequent polylines. Each polyline over which you move the pointer becomes selected. The order in which you highlight the polylines defines the order of the scan.
Creating Multiple Polylines on CAD Surfaces
