Re: Inclined hull waterline

Yes of course, and that works just fine except for the need to export the data as well, which doesn’t work.
But I’m trying to come up with an alternative solution.
This is an ideal off the top of my head:
Export the model as .dxf 3D Mesh and 3D Polylines to 3D CAD software. In my case, i use Punch! ViaCAD Pro v7. Append each name with its contents type, such as “… DXF 3D Mesh.dxf” and “…. DXF 3D pl.dxf”.
Import individually singly each dxf into your CAD app and suitably adjust the layer names if necessary.
Find the sounding pipes or overboard discharges, and so on, that are related to downflooding points. Select them all and turn on their points if that is necessary to select, move, or lock them.
Lock the end points that are above the waterline or at the waterline. If possible, make them further non-selectable after locking them. If you cannot do that, then I have an idea in a few steps past this paragraph.
De-select everything.
Now, select the hull that will be trimmed, rolled, heeled, etc.
Adjust the x, y, and z angles as desired.
If this idea works, then you should see the locked lines “grow” in some direction in accordance with the displaced positions of the model’s movement.
Idea: if that doesn’t/won’t work, then orient the model as desired and then draw rays vertically from the submerged points you’re tracking or exporting to your database. Note the distances and positions.
This obviously is tedious, but it may work. It really will depend on the CAD package you’re using.
Alternatively, to avoid dealing with a massive select/de-select mess or nightmare:
— leave the hull in place and rotate the water (a big square or circle or trapezoidal shape),
— fire out the downflood and discharges positions the rays up to or through the water.
— Segment the lines and one-by-one select the lines that remain, and then get their x2 coordinate points.
It’s a PITA doing it this way, but this is likely how I’m going to do it.
I hope this is useful or helps you arrive at some more workable ideas.
