Use the **Construction Plane** tool to create custom reference planes. Some examples of creating construction planes include:

- Creating a plane at the desired location for a new sketch.
- Creating a plane that can be used as a mirroring plane.
- Creating a cutting plane for splitting bodies or making sectioned views.

Planes are infinite but are represented in the modeling space with a size based on how they are defined. For general information regarding construction geometry, visit Understanding construction geometry.

## Creating a Construction Plane

To create a **Construction Plane**:

- Go to
**Add**>**Construction Plane**.*For other methods of accessing this tool, visit Accessing tools.* - Select
**Type**and choose a construction plane type. - Select appropriate references for the type of plane you chose (for details, see Construction Plane types).
- Select
**Done**.

You can use Shapr3D's Adaptive User Interface as a shortcut for creating some construction plane types. To make use of this shortcut, pre-select an element in your project that will be used to define the plane, then select **Add Plane **from the customized menu at the left. After defining the plane, click in an empty area of the modeling space to complete the command.

## Construction Plane types

You can define a **Construction Plane **in several different ways. Select the type of construction plane you want to define from the **Type** menu. The tooltip at the top of the modeling space will provide you with directions on what you need to do to create the type of plane you have chosen

**Perpendicular to Curve at Point**

Use the

Perpendicular to Curve at Pointtype of construction plane to create a plane that is normal to a curve at a selected point. Follow these steps to create this type of plane:

- Select an existing curve, such as a curved edge or sketch curve.
- Drag the point that is generated to position the plane as desired.

**Perpendicular to Edge at Point**

Use the

Perpendicular to Edge at Pointtype of construction plane to create a plane that is perpendicular to a linear element located at a selected point. Follow these steps to create this type of plane:

- Select a linear edge, axis, or sketch line.
- Select
Next.- Select an existing point or select anywhere in the modeling space to define a point where the plane will be located.
- Optional: Drag the point to reposition the plane. The point will snap to the grid, sketch geometry, or body geometry.

**Parallel to Face at Point**

Use the

Parallel to Face at Pointtype of construction plane to create a plane that is offset from an existing planar element and located at a selected point. Follow these steps to create this type of plane:

- Select a face, plane, or closed sketch.
- Select
Next.- Select an existing point or select anywhere in the modeling space to define a point where the plane will be located.
- Optional: Drag the point to reposition the plane. The point will snap to the grid, sketch geometry, or body geometry.

**Offset from Face**

Use the

Offset from Facetype of construction plane to create a plane that is offset from an existing planar element. Follow these steps to create this type of plane:

- Select a face, plane, or closed sketch.
- Select
Next.- Define the offset distance for the new plane using these methods:

- Drag the arrows
- Enter a distance value into the dimension label.

**Through Edge at Angle**

Use the

Through Edge at Angletype of construction plane to create a plane that is rotated about a selected linear element. Follow these steps to create this type of plane:

- Select a linear edge, axis, or sketch line.
- Select
Next.- Define the angle to position the plane using these methods:

- Drag the arrows
- Enter an angle value into the dimension label.

**Midplane**

Use the

Midplanetype of construction plane to create a plane that is centered between two selected planar elements. You can select faces, planes, or closed sketches to define this type of plane.

**Through 3 Points**

Use the

Through 3 Pointstype of construction plane to create a plane that is defined by three selected points. Follow these steps to create this type of plane:

- Select existing points or select anywhere in the modeling space to define the three points for the plane.
- Optional: Drag the points to reposition the plane. The points will snap to the grid, sketch geometry, or body geometry.
