I see what you mean...I enter a dimension of 5.5555555555555555 mm, and it is saved as 5.5555559999999993 mm. I guess my parts will never be perfect. It seems to be an error in the sketcher constraint entry window. If you enter the value in the data tab, it is not rounded. Not ideal, but a workaround if you want to be that particular.
Randy, why speaker designers quit carving half-cabinet models, extrapolating a table of offsets and leaving the fine details to be worked out on the lofting floor is beyond me.
BTW, I recall reading a similar thread on the Fusion 360 site. It dealt with hull design but the resultant problems sounded similar.

I am only a school drop out and not very educated, so much of earlier responses is beyond my pay grade. But what I can work out is this is a geometry issue (if that is even the right word)
I am glad to see your response. I am the uneducated one here talking to the experts as in the quote below
But I have been trying to pass on my finding and my workaround by saying things like, "more exacting to carve out of a block by pushing and pulling of facets as well as terms like extrapolating a panel from the face to loft onto the board". And that If CAD displays rounded off numbers and this is used to locate the next part, it will never line up. How are you able to understand this when the experts can't? They make you feel stupid with their offhand brushoffs without ever actually not skipping over the presented info
A boat sim in FreeCAD will have negative buoyancy and if there was displacement output screen, the vessel would show as sunk unless FreeCAD could model a filler putty!!!! What I have come across would also explain a lot of print birdsnests. A true expert would respond to this by ignoring the print implications just raised and say something about just how accurately they can cut wood just like a padre in full form when asked about some weirdness in the book

It is very upsetting when the experts skip over the presented material, brush off the findings and their implications, and call user error. Or weasel out of recognising a system limitation by saying make a bug report. Well, this is not a bug. This is how the program works, and I maintain that the developers must be aware
My recommendation to new users is to rely less on overlaying sketches on top of previous sketches and more on tugging on faces

Well man, I'm interested and have a growing need to gain at least a basic skill level with fusion but haven't plunged in yet. As such, I admire your efforts and I'm sure you'll get there.
BTW, the fusion thread I referenced, if memory serves, suggested that the OP's problem of a disconnect between using different design modes were a non-issue with the step up to Autocad. Go figure...
Boats? Not sure what happens between now and picking up wood, but the i550 is in the early running.

This says a lot about the design. West systems are the documentation to follow for superior builds using board materials in FRP
Good choice. I love designing watercraft and have built my designs to work well as commercial fishing and charter. Currently have 6m cat based deck boat under build and a 3.5m centre console with limited GEV and a 4m cat based beach deck boat
Your 18 is a reasonably easy build once you get used to the process. For some fun. Load up Carlson Hulls and the sharpie type template. You can adjust it to build yourself an RC model from thin balsa sheets. Good way to get familiar, and I find it superior to even made a cube box. Hulls is really fun to mess around in. Such a simple program yields pro results in minutes
I've done a little S&G and a bit more strip building. I'm certainly no expert but am fairly comfortable with both.
The big wooden boat fest is next month and there'll be plenty of home built small craft, many S&G, with at least a few sport boats. I might get lucky and see an i550 in person.

Randy, we'll see... I've only built traditional cabs to date but I'm planning on adding some curves on the next go- round. Likely vac bagging multiple 3mm ply courses over/in a mold as a one-shot layup. I'll post a pic after a test panel.
Strip building def has its strengths. I only knew of it as a canoe/kayak home builder technique but found out it's used as a fast prototype method for some of the big N American canoe manufacturers and I've seen 30'-40' performance race boats built of w. red cedar strip/carbon that have fared well. Picking out stock is nice too. Everyone else wants vertical grain but face grain cut into strips leaves nice VG stock 👍

I have been looking for a multipetal horn design to build with stitch and glue. Also am using very thin ply strips in edges up with black and red thickened epoxy as filler for the faces of the sound desk that the digital mixers and midi controllers would slot into under removable lexan covers. This should suit the name Volcano Sound System well
Btw, have you looked at cold moulding as an alternative to strip building? It can remove some headaches of the strip system, but is harder to find the strips in the first place. Timber suppliers can sometimes have cover sheets that are just a single shave and in good wood like birch so very good place to source. Just keep it in the speaker enthusiast community. They cost next to nothing and usually just binned

Nice, post up some pics when you can.
I'm familiar with cold molding via Ian Nicolson's (sp?) book from the early 90's and was fortunate enough to see it used during a 2 man scull build. It's a fairly ingenious method... maybe I'll try my hand at it some day. I do live in timber country and have a good working relationship with a mill right down the road.
