The 3D Markups Dimension commands are called from either the Dimension, Angles, or Part Dimension menus on the 3D Document Toolbar
Selecting a vertex point
A 3D design is built from lines, triangles, and other polygons. Vertex points are the points of intersection between these figures that underlie the 3D design. When you choose a command that requires you to select a vertex point, the pointer appears as an arrow with a small "x" at the tip when over the Viewport. Red dots designate available vertices on the model. (If you do not see the red dots, you may want to go to the 3D Viewer Options page of the Options component and select the Vertices visible on picking check box.) A cross-hatch indicates when the pointer is properly positioned over a vertex point. A yellow dot indicates that you have successfully selected a vertex point.
Selecting an edge or arc
Some 3D Markup Dimension commands, such as Edge Length and Arc Diameter, require you to select an edge or arc that already exists on the model. When the pointer is properly positioned over an edge or arc, a line or circle highlight will appear.

Vertex Coordinates - Measures the X, Y, and Z coordinates of a point on the model. How...
Arc Center Coordinates - Measures the X, Y, and Z coordinates of the center of the arc on the model. How...
Edge Length - Measures an existing straight line on the model. A line will indicate when the pointer is properly positioned over an edge. How...
Thickness - Measures the distance between a surface you pick and the nearest surface.How...
Vertex to Vertex - Measures the distance between two points you select on the model. By default, this command measures a line directly connecting the two points. How...
You can also choose to measure the distance between two points with respect to the X-, Y-, or Z-axis by selecting "Along X", "Along Y", or "Along Z". Or you can change an existing Vertex to Vertex Distance to measure the distance between the two points with respect to the X-, Y-, or Z-axis by selecting the appropriate choice from the right-click menu. How...
Vertex to Edge - Measures the distance between a vertex point and an existing straight edge on the model. How...
Arc Center to Edge - Measures the distance between the center of an existing arc on the model and an existing straight edge on the model. How...
Arc Center to Arc Center - Measures the distance between the centers of two existing arcs on the model. How...
Surface Point to Edge - Measures the distance between a point on a surface and an existing edge on the model. The "line" formed by the selected edge will be extended in space and the distance measured will be between the point on the surface and the nearest point on the "line" of the selected edge. How...
Surface Point to Surface Point - Measures the distance between two points on surfaces of the model. How...
Distance Between Two Surfaces - Measures the distance between two parallel surfaces on the model. How...
Sum of Connected Edges - Measures the sum of any number of connected edges selected by the user. How...
Minimum Distance Between Edges - Measures the distance between two edges of the model. How...
Boundary Center by Edges - Measures the the center point of a bondary on the assembly. How...
Arc Diameter - Measures the diameter of an existing circle on the model and draws the circle. Measure an Arc Diameter
Arc Radius - Measures the radius of an existing circle on the model and draws the circle. How...
Circle by Three Vertices - Draws a circle that passes through three selected vertex points on the model and measures the circle's diameter. This command draws a visible diameter that passes through the first point you select. The label also lists the X, Y, and Z coordinates of the circle's center point. You can also choose to show only the arc that runs through the three points by selecting Draw Arc from the right-click menu. How...
Three Vertices Angle - Measures an angle defined by two segments with a common vertex. You will pick the first point of the first segment, the vertex point, and finally the endpoint of the second segment. It is important to remember that the second point you select will be the vertex of the angle. Flip this angle's measurement by selecting the Flip Axis command from the right-click menu. How...
Two Edges Angle - Measures an angle defined by two edges on the model. The two edges picked must be co-planar How...
Two Surface Normals Angle - Measures the angle defined by the normal vectors of two surfaces. How...
Vertex to Surface Normal Angle - Measures an angle defined by the line between a vertex point on the model and a point on a surface and the normal vector of the surface. How...
Surface Normal to Edge Angle - Measures an angle defined by the normal vector of a surface and a straight edge on the model. How...
Two Vertices Draft-Angle - Measures an angle defined by a line between two selected points and the X-, Y-, or Z-axis. Flip this angle's measurement or change the axis used to compute it from the right-click menu. How...
Surface Draft Angle - Measures an angle defined by a surface normal vector and the X-, Y-, or Z-axis. Flip this angle's measurement or change the axis used to compute it from the right-click menu. How...
Volume - Measures the volume of a part. How...
Surface - Measures the surface area of a part. How...
Center of Mass - Lists the X, Y, and Z coordinates of the center of mass of a part. How...
