Geometrical calculator for 3D objects

Scroll

In 3D models the following geometrical calculator commands are available:

•(for linear values),

•for angular values,

•using the Copy Value.

Geometrical calculator for linear values

	Command	Command purpose and step-by-step instructions
	Edge Length	Readout of the length value of a 3D curve, a curve in a sketch or an edge. 1.Hover the cursor over a curve or an edge – the object will be highlighted, and its icon will appear near the cursor. 2.Click the object – the length value will be calculated and passed into the Parameter Panel field.
	Distance Between Two Objects	Readout of the distance value between two objects: coordinate and construction axes and planes, faces, edges, vertices, 3D curves and points. Objects can be specified in any combination. If a revolution surface is specified, then the object to measure distance from/to is the axis of rotation; if two revolution surfaces are specified, the distance between axes is measured. 1.Click on the first object. 2.Click on the second object – the distance value will be calculated and passed into the Parameter Panel field.
	Diameter	Readout of the diameter value of a circle/arc in space or in a sketch, s round edge, a cylindrical or spherical face. 1.Hover the cursor over the object – it will be highlighted, and its icon will appear near the cursor. 2.Click the object – the diameter value will be calculated and passed into the Parameter Panel field.
	Radius	Readout of the radius value of the specified circle, arc, cylinder or sphere. 1.Hover the cursor over the object – it will be highlighted, and its icon will appear near the cursor. 2.Click the object – the radius value will be calculated and passed into the Parameter Panel field.

Geometrical calculator for angular values

	Command	Command purpose and step-by-step instructions
	Object direction (only for bend angles in sheet metal operations)	•If a straight–line object is specified: readout of the angle value between the specified object and the base face of the bend. The specified straight–line object should be perpendicular to the bend line. •If a flat object is specified: readout of the angle value between the base face of the bend and the line of intersection of the specified object with the plane perpendicular to the bend line. The specified flat object should not be perpendicular to the bend line. 1.Hover the cursor over the object – it will be highlighted, and its icon will appear near the cursor. 2.Click the object – the angle value will be calculated and passed into the Parameter Panel field.
	Arc aperture	Readout of the value of arc aperture in space or in a sketch, an arc–shaped edge. 1.Hover the cursor over the object – it will be highlighted, and its icon will appear near the cursor. 2.Click the object – the angle value will be calculated and passed into the Parameter Panel field.
	Between two objects	Readout of the angle value between two specified objects: coordinate and construction axes and planes, 3D curves, curves in a sketch, edges, faces. Objects can be specified in any combination. 1.Click on the first object. 2.Click on the second object – the angle value will be calculated and passed into the Parameter Panel field.

Copying parameter values

The Copy Value command allows to assign the same value to a parameter of the object being edited as another already existing object has. Parameter values are copied only between objects of the same type. For example, you can copy the length of an existing line segment into the line segment being edited, but you cannot copy there the length of a broken line segment.

To set the source of the parameter to copy, specify the desired object in the Design Tree or a primitive belonging to it in the graphic area (an edge, a face, etc.). In the graphic area, an object that can be specified to copy a parameter, is highlighted when the cursor is hovered over it, and its icon is displayed next to the cursor.

After specifying the source object its parameter value is passed into the field for which the geometrical calculator was called.
