2D Features
Line Feature
Creates a GR-Line feature that dynamically builds a line from the associated points.
Lines Features report the following criteria:
-
Length. Which is based on the extent of the measured points associated with the line.
-
Linearity. Which reports the relative straightness of the line. It is computed as the Max - Min deviation.
-
Origin X, Y, Z. Which reports the origin point in the current working frame.
-
I, J, K. Which reports the direction of the line in the working frame.
-
Projected Angles (Rx from Y, Ry from Z, Rz from X).
-
Angle Between . Which reports the angle between the nominal and measured lines.
-
Mutual Perp. Dist.Which reports the closest intersection point between the nominal and measured lines.
-
RMS. Which reports that RMS of the measured line.
Line Fit Settings include the following specific considerations:
Use of Point Offsets Lines typically do not have any fit settings and ignore the offsets saved in the points. The expectation is that points measured in a line define the axis of the line. However, if a projection plane is applied the Fit Settings will offer a means to offset the resulting fit line in either of two directions using the offsets from the points.
Nominal Direction The nominal direction of the line can be adjusted using the Reverse normal Vector option. The normal vector can also be set dynamically to match the nominal line using the Align with Nominal check box. This ensures the Angle Between value reported is always the smallest possible angle.
Cardinal Points Three cardinal points can be built using the GR-Line feature. These include both end points and the mid point of the line.
Dynamic Intersection Lines
The following additional Intersection and axis Lines can also be created:
-
Cone Axis. Computes and builds the axis line of a selected cone.
-
Cylinder Axis. Computes and builds the axis line of a selected cylinder.
-
Two Plane Intersection. Computes the intersection line between two planes.
-
Bisect Two Lines. Builds the bisection line or average line defined by two selected lines. Note that the bisection line using the normal direction of the two input lines. This means that two lines that are nearly parallel and the same direction will result in a line that is also nearly parallel between them. But if they are the opposite direction relative to each other it will build a line that is nearly 90 degrees to each. Within the Line Fit Settings is a Reverse Solution option to reverse the correct this. Right-click on the input lines and enable the arrow head settings to visualize their direction if needed.
-
Slot Centerline Along Length. Computes and builds the the central axis of a slot.
