adding profiles for a round top
adding profiles with scales to loft the internal hull ( yellow )

Thanks guys - finally did it somehow!

That's great Gord!

@ Corchet What a diversity of variable floating conception! :)

@ Gord Cool result!

Else...;)

Thanks! Really interesting!

OK, another issue on my next project. I'm doing a Clyde Puffer. I have the hull done and in solids. Yes, I know it could be fairer, but whatever, the master model can be sanded slightly, and these things had lumps everywhere!

I have 3 solids, but try as I might, I cannot get the two stern ones to boolean into the others. I tried Diff and Union, but no result. Why won't it do this. I can cut a line through the sterns, but I can't use this technique to trim off the ends to be flush for some reason. Nothing works again!

Thanks!

Gord.

Hi Gord, it's the bottom curved surface of the stern pieces. There are damaged trimming boundaries in these spots:


And there's a kind of mutated micro shelf in this area:



How did you create this piece, was it a result of a Shell operation? It kind of looks like the sort of stuff that Shell messes up on.

It's also possible that this very thin area here could be considered an area of self intersection:



It's not generally good to have opposite sides of a solid squish down to such a thin area.

If you have any earlier stages of these pieces if you can post them I might be able to tell you where things started to go wrong with them.

Yep this serial of videos is very instructive how is made a wood boat! !

Hull Plan of Tally Ho from another cool site : https://davestallyhomodel.blogspot.com/2019/02/the-first-steps.html



Amazing stuff!

Thanks. Yes, it was network surface then boolean joined. It's not repairable then? I know I'm doing a difficult shame again as one part has to go down to basically nothing, whilst the other upper part has to be 90 deg. to it. Not sure what to do now. It is OK on loft, but it doesn't follow the plan shape too accurately though.

Maybe you can see the videos about hulls about this site (and free prog ;)

Hi Gord,

re:
> Yes, it was network surface then boolean joined.

It looks like there are just a couple of spots where the endpoints don't touch. It would probably be a good idea after you construct one of these networks that you want to join to other straight parts, to edit surface control points and ensure the end control points are all trued up to be flat so the ends will be planar.

It's probably things waving around just a little bit out of being planar that is causing enough misalignment to be problematic.


> It's not repairable then?

It might be, I'll take a crack at it.

- Michael

Appreciate it, thanks!

Is there a scrip I can run to allow me to see these problem areas highlighted larger? I use N, but it only shows the whole edge.

G

Hi Gord, there isn't any script for that, you just zoom in closely especially on corner areas where things join up. You can use the "Zoom area" tool to zoom in centered on a specific spot.

- Michael

Hi Gord, here is a stern piece which should be all trued up. I think this could use it here too though:



- Michael

Hi Gord, I guess I planarized a little bit too much, I guess I should not have pulled this one up to be planar:


I was kind of thinking the upper surface wanted to be a simple straight extrusion.

- Michael

Hi Gord,

Your constant issues with lines not meeting or touching makes me wonder whether you have "Object Snap" switched "ON"..?
If not, then may be that could help to explain a lot of your issues?

HTH, Colin

Hi.

Thanks, I thought I did do - see the screenshot. Must I alter numbers somewhere?

Gord

Funny! Never used even don't remember that is existing! :)

Maybe because i don't use millimeter as unities
Seems all is enabled!

gaps and a huge amount of points on curves ... don' t forget to rebuild

the central part have issues ... lonely faces .... better to contruct this as an extrusion + boolean hole

and 2 half hulls ... union give the baby solid

i add a round piece ... à l'avant qui fend les flots ;) ( 3dm joined )

ps i can't reproduce the exact shape of your hull ... cause you post the result of the network and not the curves needed to built it ;)
