A Guide To Woodwork For Inventor Cover Position Settings

When you are generating manufacturing information (part code, name, size, and material) or linking system data to the information in the part labels in Woodwork for Inventor, it is important to indicate which side of the part a cover is applied to and what type of cover it is. For example, the part is covered with a 2mm edge band on the right side and a 0.45mm edge band on the left side. On the other hand, it is important to bear in mind that the part is covered with a veneer on the top and with paper film on the bottom.
It might be important for the user to know how Woodwork for Inventor identifies part sides and how this is related to entries for the specifications generated. The image below demonstrates how it identifies the sides of the part.
Woodwork for Inventor automatically sets the grain direction of the material during the initial material assignment process. The grain direction algorithm searches for the largest flat face and the two longest edges on that face that are perpendicular to each other.
If this is not achieved, other rules are applied which allow the initial grain direction of the material to be set. If the constructor is not satisfied with the grain direction that has been automatically set, he may modify it using the Woodwork for Inventor tools, by specifying another plane for calculation or selecting a different grain vector orientation.
Consequently, if a part is oriented with respect to the view as shown in the figure, it is considered that the main face is pointing upward, and it is treated as a top side. The bottom face will be on the opposite side of the part. The red arrows in the images show the grain orientation to the right, whilst the left is on the opposite side. The front and the back faces of the part are arranged respectively.
Part sides are always defined in terms of the geometry of the part rather than the workpiece. However, the rotation of the grain direction determines which side is treated as front, right etc. The images below show how the rotation of the grain direction affects the part sides.
As the grain direction is shifted to the next grain direction angle segment, the part sides change. The images show how a minor change to the angle of the grain direction has no effect on the part sides, although once the 45 degree angle is exceeded, the sides do change.
