I can't shell my boat model

Anonymous — Fri, 29 Jan 2021 02:23:54 GMT

Hi I am trying to shell my boat hull but get an error message for any value under 8mm. I tried to offset the faces in surface mode and they did offset but some in the wrong direction.

can anyone help please?

Hello thrjesse,

I took a look at this. There is a problem with shelling at the nose of the boat and at the windscreen (do boats have windscreens? I don't know). The difficulty is that the diffferent surfaces in these areas can each offset but the offset surfaces won't "glue up" to make a watertight sheet. Cropping these regions away (combine-cut) leaves an adjusted boat shape which will shell to, say, 2mm.

I imagine that you don't want a boat that's this shape; you need that nose shape as you designed it on the outside of your shell but maybe it's not so important what the shape of the inside is.

I started to put together a longer timeline to demo how to build a model with your boat as the outside and the adjusted inside shape (I would offset a surface model and then use that offset surface body as a tool for split-body), but I decided to hold off - I'm not sure what thickness you're really after, or what shape you want around the top of the boat - do you have an idea of some "open faces" for the result you seek? Or are you seeking a complete hollow boat with a void space inside?

hi thanks for your time.

I am aiming for a large opening in the top of the boat. I have adjusted a lot of the top section that was giving me trouble an have finally found a shape that shelled to the 1.2mm I was looking for.

it looks a bit different now but that is not too critical.

I think it will still do the job. I may try to introduce the elements that I had to remove later and see how that goes.

thanks again.

Thanks for the update! Glad you found a way to get to the shell.
