When a stringer passes through a frame, Workshop will insert a cutout to allow the stringer to pass through the frame. You specify which stringer shape and cutout to use for a stringer by using the Shape & Cutout command from the Stringer menu.
To set the shape and cutout for stringer or stringers
Ø Select the stringers
Ø Choose Shape and Cutout from the Stringer menu
A dialog will appear listing the shape and cutouts you have added to the Workshop Library
Ø Click on the name of the group you wish to use
Ø Click on the name of the shape you wish to use
Ø Click on the name of the cutout you wish to use
Ø Click OK
The next time that you calculate frames, the cutouts you specify will be deducted from any frames that the selected stringers pass through.
When choosing cutouts you may specify that the stringer has no cutout by choosing “None” from the Cutout list. In this case, no cutouts will be inserted for the selected stringers.
Note:
When a stringer intersects a frame at
an angle to the horizontal the cutout size will need to be increased in order
for the stringer to pass through the frame.
In Workshop this ‘stretching’ is done by extending the midsection of the
cutout by a distance proportional to one on cosine of the angle the
upstand makes with the frame plane:
