# 3D Angular Menu

Measures an angle defined by two segments with a common point. The second point you select will be the vertex of the angle.

Once the markup label is displayed, you can also determine the reflex angle by using the **Flip Axis** command on the Markup context menu.

See Working with Angular Measurements for information on using this command and the context menu.

Note

The **Flip Axis** command works differently on a three points angle and a two points draft angle.

- On a
*three points angle*, the**Flip Axis**command measures the angle in the opposite direction. - On a
*two points draft angle*, the**Flip Axis**command flips the direction of the X-, Y-, or Z-axis segment used to form the angle.

The **Two Edge Angle** command measures an angle defined by two edges on the model. The two edges picked must be co-planar.

See Working with Angular Measurements for information on using this command and the context menu.

The **Two Surfaces Angle** command measures an angle defined by two surfaces on the model. The two surfaces picked must be

- both planar non-parallel surfaces,
- one cylindrical and one planar surface.

See Working with Angular Measurements for information on using this command and the context menu.

The **Surface Point to Point Angle** command measures an angle defined by the line between a point and a surface point and the *normal* vector of the surface. Every surface has a normal, that is, a vector perpendicular to the surface.

See Working with Angular Measurements for information on using this command and the context menu.

The **Surface Point to Edge Angle** command measures an angle defined by a point on the surface and a straight edge on the model.

See Working with Angular Measurements for information on using this command and the context menu.

The **Surface Point to Surface Point Angle **command measures the angle defined by points on two surfaces.

See Working with Angular Measurements for information on using this command and the context menu.

The **Surface Point to Circle Tangent Angle **command measures the angle defined by a point on a surface and the tangent of a selected circle.

See Working with Angular Measurements for information on using this command and the context menu.

The **Two Points Draft Angle** command measures an angle defined by a line between two selected points and the X-, Y-, or Z-axis.

Once the markup label is displayed, you can use the **Flip Axis** command on the Markup context menu to change the direction of the X-, Y-, or Z-axis segment used to form the angle. Right-click the label and select **Flip Axis** from the context menu.

See Working with Angular Measurements for information on using this command and the context menu.

Note

The **Flip Axis** command works differently on a three points angle and a two points draft angle.

- On a
*three points angle*, the**Flip Axis**command measures the angle in the opposite direction. - On a
*two points draft angle*, the**Flip Axis**command flips the direction of the X-, Y-, or Z-axis segment used to form the angle.

The **Surface Draft Angle** command measures an angle defined by a surface point and the X-, Y-, or Z-axis.

See Working with Angular Measurements for information on using this command and the context menu.
