Reference Lines on Assembly Parts and Profiles

This function is a tool that provides alignment marking on the plates and profiles on the assembly part. The default parameters REF_HEIGHT, REF_WIDTH, REF_NO_LINES, REF_DIST1, REF_DIST2, REF_DIST3, REF_DIST4 and REF_DIST5 specifies the layout of the reference lines in the welding station.

When the function is used in the PLCM, the default height and width of the welding station is shown on the screen and the user can place the rectangle around the welding unit using normal positioning tools. If the assembly part is too larger for the welding station, a message is given and no rectangle appears.

The reference lines will be shown on the assembly nesting, for checking purposes. The assembly part is updated with the reference lines and stored in the assembly nesting. If the function is repeated, the old reference data are deleted and overwritten. The reference lines are intersected with every stiffener in the assembly part belonging to the same assembly on the lowest level, and for each intersection the information about the line is stored with the stiffener. It is however required that the system is used in a way that all parts are individually stored, otherwise no marking of profiles can be done. The information is stored in such a way that it can be written to the generic file. The profile line will then mark the reference line on the profile. Thus, in the profile welding station there will be alignment marks on the assembly part to position the unit in the station, and marks on the stiffeners so that they can be aligned on the assembly part.
