Designing a jetboat with DelftShip

[Lurvio]

The most stable way I've found is to select a piece from the right side menu and then try to grab the small point in the middle of the piece. Does not work every time.

[heemi.v8]

i dont have any problems jus right click once on the piece to select it then right click hold and drag. if this doesnt work it usually starts zooming instead so just repeat the process again and it should work....  i even went back to freeship tonight to make sure it worked the same lol

Still having problems moving the pieces on the development page but I think it might be just fiddly like a lot of things in the program. 

I am having problems figuring out how to make the stringers.  I can do the extrusion part and create what I want but I cant remove the extrusion and just leave the stringer.  I have made layers for the stringer and I can make a line linking the points in the bottom of the hull that stays where the extrusion was using the intersecting layers tool.  When I remove the extrusions all I can get to stay are the lines and points but I cant extrude from that line because it is in the middle of the face and not on an edge.  It also seems to change the bottom shape according to the developability check but I cant see the change just the red.

Any ideas?   Matt.

Thanks SO much for the tutorial, it has been very helpful.  I have one issue with the stringer creation process...

I created stringers in the manner you explained and it works great, however it has created leak points.  Interestingly, it appears your stringers have the same leak points but I am not able to generate any hydro statics with the stringers in the model.  If you have any ideas on what I may have done wrong, I'd sure appreciate it.

[heemi.v8]

look back to reply number 6 its all written there with pictures. if you go to layer properties you can unselect the hydrostatics box on the stringer layer. then you should be golden

[BrokenRudder]

I had that familiar feeling I was failing to grasp the obvious!  Thanks so much heemi.v8

Are you mixing the layers in the layer intersect-tool? Insert points to the stringer-layer and find intersection with hull bottom-layer?

Try hiding one or the other of the layers to see what layer has your points.

I will give it a try and let you know.

Thanks, matt

Really struggling with the tools in Delfship. Newer free version and it's hard to find info on specifics with a google search.  Ive been trying to follow this tutorial but keep getting hung up on basics.  Is there a good guide to the tools anywhere online.  I feel stupid but I can't figure out for the life of me how to connect a line (centerline of delta) after I have extruded the bottom out.

[heemi.v8]

Im not sure i understood your question. But i made a bit of thing top maybe help you...

what you are looking at is the transom and then the start of a boat bottom. the three yellow points selected are where the delta should be but has not yet been created. All you need to do is select the points surrounding the area you want surface and click make new face (circled in green).

Also as far as online tutorials. there is the help icon in the top right which will be the manual specific to your version. other wise there is these for older versions...

there was one on the delftship forum but they seem to have shut it down?

If you could post a screenshot of the problem, we can take a look and I can possibly update this tutorial.

Still struggling with a few things.  Can't get some lines to "highlight" i guess you would call it and I think that is what is causing my "edge" issue.....screenshots.

[heemi.v8]

i have three things you need to do... heres the first one to answer your question


first two pictures i created your problem with my first hull design. third picture i selected the lines that were not "highlighted"

then i clicked the green button called set crease. basically all the red lines are hard bends. so the fourth pic is the result of hitting the set crease button.

[heemi.v8]

so here are the rest of the things i would fix.  first picture is my hull drawn in a similar fashion to yours. so first you need to set the delta line as a crease (second pic)

second you need to remove the creases going across your hull as you want the bottom of your boat smooth and curvy in this area no hard bends or creases. (third pic)

third you will get a more accurate unfold to flat panels if you remove the control points in the middle of your hull to do this simply select the line (fourth pic) and click edge collapse (highlighted in green)

[heemi.v8]

it can take abit to wrap your head around at first but once you get it, it is very useful for all sorts of stuff. Some engineering students in the US have drawn from this program then printed in 3d a small model and put it in a wind tunnel to do some testing on it. It is also possible to use these files on a cnc router. then you can go full size. for example an intake pattern for casting or a steering nozzle. Many other options too not just boats.

your doing good all those who persevere with this program
