This command allows you to create a perpendicular shape, a tangent shape, or a shape with a given angle with respect to the perpendicular of a face.
Creation Stages / Use:
Click on the icon  or choose 
 the command Surface > 
 Normal... from the drop down menu (or Modeling 
 > Surface > Normal... in the assembly document).
 or choose 
 the command Surface > 
 Normal... from the drop down menu (or Modeling 
 > Surface > Normal... in the assembly document).
Select the face creation mode:
| 
 | By Profile: The face is created using a profile (border edge, edge from an impression, projection of a sketch, etc.), located on the reference face. 
 | 
| 
 | By Isoparametric: The face is created using isoparametric curves from the reference face. 
 | 
Enter the length of the face to create.
Choose the type of surface to create:
| 
 | Tangent: The face is created on the profile or curve that is isoparametric and tangential to the reference face. | 
| 
 | Perpendicular: The face is created on the profile or curve that is isoparametric and perpendicular to the reference face. | 
| 
 | Angle: The face is created on the profile or isoparametric curve with a given angle with respect to the perpendicular to the reference face. | 
Validate with the  button.

| 
 | The profile must absolutely be the reference face. | 
| 
 | To select all tangent faces, use the rotative picking. | 
Available Options:
The Reverse option allows to change the surface side or double click the yellow arrow.
