PDM 1

The reasons you may need Reference features

• To locate a sketch for a new feature where a part surface is not available; construct a reference plane to sketch.

• To establish a plane or an edge for dimensioning; construct reference plane or reference axis.

• To provide a point for rotating or an axis for revolving features or patterns; construct reference point or reference axis

• To establish an intermediate position that is required to define other reference plane; construct a reference plane

PDM 1

Select a point and a line

Specify three points

Reference Planes

Reference plane is a rectangular plane that is tied to the model parametrically and is infinitely large. There is no limit on the number of reference planes and they can be used to create new sketches for feature operations.

PDM 1

Parallel to a plane and passing through a certain point

PDM 1

Select reference plane at an angle option

A

Select the top face and the second line to create the plane

A

A

Draw another line perpendicular to the first one at point A

Reference plane

Reference Planes

Create a plane passing thru a desired point (A) making an angle with another plane (top)

PDM 1

Select the part of the object to cut

Check Consume cut bodies

Reference Planes

Cutting an object with a plane

Select Insert, Features and choose Split

PDM 1

Creating an offset plane

Select a face and specify the offset and the number of reference planes

Reference plane

Offset distance

PDM 1

Reference Planes – Perpendicular (Normal) to a Curve

Create planes perpendicular to a curve at a certain point. Useful for sketching profiles for sweep and loft (sweeping and blending).

Select Normal to Curve

PDM 1

Select Surface and point

Reference Planes – on Surface

Create a reference plane tangent to a curved surface at a specific point.

Select On Surface option
