Generating Stringers

Adding stringers by hand can be time consuming. Workshop provides a feature which allows you to automatically add stringers at a specified girth spacing around the hull.

 

To automatically generate stringers on a surface

Ø        Choose Generate Stringers from the Stringer menu

 

A dialog will appear allowing you to enter the longitudinal and girth positions of the points on the stringer.

Ø        Type in the number of stringers you require

Ø        Choose the stringer surface by choosing one of the names from the pop-up surface menu

Ø        Type in the stringer start and end locations in the Start and End columns of the Longitudinal Spacing table

Ø        If you wish you can specify the start girth, end girth and girth spacing by typing numbers into the Transverse Spacing table. These values will override the values automatically calculated by Workshop

Ø        Select the type of stringer you require

Ø        Click OK to generate the stringers along the hull.

 

Each time you make a change to the longitudinal position of a stringer, the Transverse Spacing table will be automatically updated to show you the girth positions which will result from the values you have entered.

 

These girth positions, which are generated automatically by Workshop, are displayed in the Transverse spacing table. These girth positions will also be displayed in the girth expansion drawing at the bottom of the window. The automatically generated stringer points will be calculated by evenly spacing around the girth of the surface, all of the stringers which pass through the frame at that position.

 

Note: You can use the Help button to get information on how to use the stringer generation dialog.

 

When entering positions, you can use mathematical expressions such as 12.5-2.5 and you can also use the names of frames as variables in place of their coordinates. For example, if you want a stringer to start 200mm aft of a frame names Fr4 you would enter Fr4-0.2 in the Start column.
