Loops:
Measure Elements and Relations between Them
“CenterX”, “CenterY”, “CenterZ” – X, Y, Z-coordinate of the ellipse center;
“AxisX”, “AxisY”, “AxisZ” – X, Y, Z-coordinates of the normal to the ellipse plane;
“MaxDirectionX”, “MaxDirectionY”, “MaxDirectionZ” – X, Y, Z-coordinates of the
ellipse major axis;
“MinDirectionX”, “MinDirectionY”, “MinDirectionZ” – X, Y, Z-coordinates of the
ellipse minor axis;
“StartAngle” – start angle of the elliptical arc;
“EndAngle” – end angle of the elliptical arc;
“Perimeter” – loop perimeter.
Measured Relations
The list of relations that can be measured by the command “PM: Measure Element or relation
between two Elements” depends also on the selected objects of the measurement. Follows below is the
list of relations, with specified pairs of 2D and 3D objects, for which such relations can be defined.
The functions distance() and measure() are used in this command for measuring parameters. The
syntax of these functions is described in the chapter “Variables”.
2D elements
3D objects
“Distance” – is the distance between a 2D node and another 2D node, construction line, graphic line or
hatch (the order of selecting the measurable entities is not significant);
“Angle” – is the angle between two lines, segments or a line and a segment.
“Distance” – is the distance between two arbitrary 3D objects that are 3D construction entities (except
for LCS), operations or such topological objects as an edge, loop, face, vertex.
“GeomDistance” – is the distance between 3D points, 3D curves or surfaces corresponding to two
respective 3D objects of the types: 3D node, vertex, edge, face.
“Angle” – is the angle between directional vectors of two 3D objects. Listed below are 3D objects, for
which a direction can be defined (and, therefore, this relation can be calculated). Additionally specified is
what will be selected as the direction vector for each object:
• for a 3D path, edge or open 3D profile lying on a straight line – the line direction;
• for a 3D path, edge or open 3D profile lying on an ellipse (circle) – the vector directed from the
center of the ellipse (circle) normal to the plane of the ellipse (circle);
• for a flat 3D profile; workplane; flat face; an operation body consisting of one face lying in a plane –
the normal to the plane;
• for a cylindrical work surface; cylindrical face; 3D profile lying on a cylinder; an operation body
consisting of one face lying on a cylinder – the axis of the cylinder;
• for a 3D profile or face, lying on a cone; an operation body consisting of one face lying on a cone –
the axis of the cone;
• for a toroidal work surface; 3D profile or face lying on a torus; an operation body consisting of one
face lying on a torus – the axis of the torus.
