Calculating Frames

You can use the Calc Frames commands to calculate the frame shapes including any internal openings. If you have finished setting up all of your upstands and stringers, the calculated frame shapes will also include cutouts to allow stringers to pass through the frames.

Note:

Frame shapes will be calculated using the precision setting at the time you use the Calc command, not the precision setting when you define the frame. This means you can define your frames with precision set to medium, then change to highest precision to calculate the final shape. Also see Workshop Precision on page 10

Once the frame shapes have been calculated, the 3D shape of the frame will be displayed in the drawing windows and the 2D shape of the frame will be displayed in the Part window. You can use the pop-up menu at the top left corner of the Part window to choose which frame is displayed.

 

If stringer display is turned on in the Structure command from the Display menu, the stringer shapes will be displayed along with the frames in the Part window.

Deduct Skin Thickness

By selecting “Deduct Skin Thickness” in the Frames menu, the skin thickness is taken into account. If the skin thickness throw direction is set to inside or centred in Maxsurf and the “Deduct Skin Thickness” is selected in the Frame menu, the skin thickness will be deducted from the perimeter of the frame. Stringers and stringer cutouts will also be moved to the correct position on the frame.

Note:

The plate thickness that is assigned during plate development is not related to the skin thickness of the Maxsurf surfaces.
The surface thickness as assigned in Maxsurf is deducted from the frame perimeter. The plating thickness as assigned during development is ignored in the “Deduct Frame Thickness” command.
