Syntax Framing System tab ExpressMarine

Draw button at the top draws the frame scales in the Rhino window. This is also triggered when leaving the Framing System tab. 

Decimals: Set the number of decimals for the units in the Frame list. 

Prefix: This option can be used to set a prefix in front of the frame numbers. E.g. L, V or T showing that it is Longitudinal, Vertical or Transverse frames. If the Rename frame option has been used on a given frame this prefix will not be update for this frame name and the custom name will be intact. I.e. This option will set prefix for each frame that has not yet been given a custom name. Once a custom frame name has been set (Rename frame), they become decoupled.

Origin: Set the location where #0 is located. Example: X = 0 resides in AP and #0 is located 0.2 meter ahead of AP (Positive direction towards FP) then Origin should be set to 0.2

Start and End: Define the start and end of the frame definition line to be drawn in your model, in length unit. Rounded to nearest frame. This is purely a visual limitation, and frames outside of the visible range are accessible to be used. 

Longitudinal: Start is the leftmost point of the drawing and End is the rightmost point of the drawing. Left of origin is defined as negative. 

Transverse: Starboard is defined as negative in ExpressMarine. Start is negative and the point you start drawing the frames at starboard. End is where you stop drawing at port side. 

Vertical: Start is the lowest point in the drawing where you would like the frames drawn for, End is the highest point in the drawing.  

Frame list: This is the box at the right hand side. Every drawn frame are shown here, alongside its location, in length unit.

Rename frame: Set custom name for selected frame. That frame can then be referenced (e.g. as a limit) either by the frame #, or its custom name. Once a custom frame name has been set using this Rename frame option, they become decoupled. 

Table with spacing and End#:

Spacing: Enter in the interval between each frame, in length unit. The amount of decimals can be set in the decimals setting at the top of the window. The start frame is never explicitly supplied, but runs from the previous frame definition's End #, or the initial start point. 

End #: Enter in the frame number without the #(hash). E.g. 1,2,3 etc. The last frame definition shall not have an End #. This value can be a decimal. The row order is indifferent; it is dictated by the End # column.

Example: 

Prefix set to L for Longitudinal frames, Origin set to 0, Start drawing the definition in the model at -5m and stop at End = 10m. From #L-10 to #3 the spacing is set to 0,5m, then the spacing changes to 0.8 from #3 till the foremost frame at #L14. 

Modifying the framing system will render the model outdated. Update the model. 

Note:

End # can be supplied as a decimal value, as stated. Consider this example:

Origin: 0

First frame definition: Spacing 1, End # .5 (Leading zero is optional. The hash symbol shall not be included.)

Second frame definition: Spacing 2

This means distance between #-1 and #0 is 1.

Distance between #0 and #1 is 1.5.

Distance between #1 and #2 is 2.

However the distance between #0 and #1 is not linear. #.5 is not in the middle, at length .75, but rather at .5.
