Special Features for Normal Templates

In the text below the expression base line seams refers to the two seams that intersect the base line, that means, normally the two shorter edges of the plate. For the definition of the base line please refer to the document for shell plate development module. Normal templates are generated as described below.

• The sight plane is set so, that the distances between the plane and the opposing plate corners on the base line seams are equal. The shortest of the two distances can be set in the default file.

• The plane of the middle template is placed across the plate approximately at the middle point of the plate. The corners at the end points of the base line seams are used in order to decide this point.

• The template planes are all parallel and set at equal distances. The maximum allowed this distance can be set in the default file.

• The minimum distance from the outer templates to the base line seams can be set in the default file.

• The sight line is set as close as possible to the middle points of the templates. This choice can be overridden by information in the default file.

When the module is working as described in this Appendix it may be controlled to produce two types of templates:

1. Always create Normal templates independently of angle between the frame plane and the plate.

2. Create standard frame templates normally. Normal templates are generated only if any of the frame templates would get an angle to the plate that is smaller than 75 degrees.
