Hi Biber, as usual I started from blank:
Got your .txt file and imported as “coordinates” – ’cause any other format gave num.err. and I do not bother fix it –
Then gracefully add some faces… A nice canoe hull!

Three in a line: coordinates, hard chines, flush.
I do not see problems…
Let me know, please.
Bye, Jurgen.

If you need to isolate and correct some of them, Polylines ARE a real pain, but life’s not easy: we could be small rodents wandering through saurians legs although.
As partial reward I can say other CAD offer no better treatment, at last layers assignement in DS linesplan .DXF is plain and even:
in other cases it’s not so easy.

[giorgio zuppin]

All right… “simply” maybe NOT so appropriate. Polilynes et al. need a huge time spent in choose and make visible/ or not.
But ref. lines, grid, intersections came all in own layers so…
Bye, Jurgen.

[giorgio zuppin]

Sorry Mr.J, it’s all fine but I got rid of unwanted stuff simply by layers management.
Working in autodesk actually, no problems.
Maybe something I’m not aware?
Bye, Jurgen.

[giorgio zuppin]

You jolly ol’…
Have a look:

Congrats, but Sciarrelli added a bit of magic, Bat is marginally faster and nimble even if Sorella’s owner does’nt agree.
About offsets: lost in outer space I think..we’ll manage, life deserves more.
Bye, Jurgen.

It depends on the filetype obtained with scanning.
If you have some simple image files may be imported as a background image, with a bit of training and some patience the result could be acceptable for a model: just do not think about five digits precision…
As a sample

Only from sideview and average measures, not a precise copy of course.
Bye, Jurgen.

Antò, fa caldo… – sorry, I promise, no more Italian –
I’ve made a quick check: no changes is SCALE et al.

Try again and let me know.
Bye, Jurgen.

[giorgio zuppin]

Just in case…

A quick draw using basic DS model, scaled trasversally, mirrored, joined by a box – modified –
A sketch works better to understand.
Bye, Jurgen.

[giorgio zuppin]

Hi, I can suggest a procedure, it’s not complicate but as a beginner do not give up! Try to follow…
First draw your hull as per normal – control grid left to the centerline.
Now move it at a convenient distance – left side of course – use “move” command in TOOLS.
Then MIRROR, care of plane placement and you have a complete hull at the right offset.
Still in TOOLS draw a rectangular body representing the joining struct.
The not so easy part: delete faces at centre and the one facing your hull: here create a gap in the late and fill it using “add” function.
With a bit of patience and some inevitable strong language here’s a basic cat, the refinements are up to you, after all that work I’m sure you’ll find easy!
Bye, Jurgen.
P.S. : I omitted a lot of small steps for sake of concision, in need ask.

[giorgio zuppin]

No news about offsets.
Here’s the file with weights in layer properties, conjectural at least – we are not talking about metal sheets…

Having some fun with others CAD:

Enjoy holidays.
Jurgen.

Till we wait for mission control, something to cheer up the folks…

I shown her on a clip some times ago, then despite absolute lack of plans I tried to figure out her lines.
Of course it’s a work in progress at the moment I’m focusing on gaussian curvatures – hull’s smoothness –
They could say it’s a small bathtub, but I saw her literally flyng in bad weather – worst the better – despite her tiny appearence.
I’ll be pleased if you develope some interest in this design: I can’t manage a real construction…
A model, yes but it’s not enough.
Bye, Jurgen.

[giorgio zuppin]

All rigth, it’s time to say: Houston we have a problem.
As a fact I am unable to import offsets, all I get is “invalid numeric input” about .txt files created a couple of secs. before by the same program…
Ideas?
Jurgen.

[giorgio zuppin]

Well, something weird happens.
Your .txt appears to be a hull abort, no bow or stern recognizable but a hull, yes with some strange control points position.
Meanwhile “” in mine nothing happens “” ( Holy Spyke Milligan Protect Us ) same “invalid stuff” message.
Check please your original layers arrangement, maybe stupid and you’ve already checked…nevermind do it anyway.
We’ll keep in touch.
Jurgen.

[giorgio zuppin]

Tried to replicate the issue:
But…
BAT2016.txt
DS – latest version – says “invalid numeric input”
Any suggestion?
Thanks, Jurgen.

[giorgio zuppin]

Sorry, no good news I think.
By your post I can guess the.dxf it’s a 3D polylines export – btw I strongly suggest a saved .dxf linesplan AND one of 3D mesh as backup – a work of forensic reconstruction could be only alternative.
Focus on obtain an image suitable for background in a new .fbm.
In a CAD ambient and with patience it’s possible to intersect your polylines with planes till a simil-linesplan get life.
Imported stations as .txt as check-control too.
Now it’s up to you: Be positive, what’s done once should be replicated!
Bye,Jurgen.
