Holding hands:))

[lazeyjack]

Guys, gals.
you can probably see by my posts that I,m a hands on man, BUT I do struggle with CAD
Can anyone PLEASE spare the time to hold my hand with Maxsurf(yes I,ve read and reread the manual)n I have literally done 200 hrs on this and got nowhere at all
thanks Stu

[Bergalia]

You and me both, Jack :confused:

[Crag Cay]

It's best to ask questions about specifics and even upload the file with which you are having problems. Then I'm sure you will get the help you need.

Many of us don't have the time to simply 'hold hands' but are willing to help!

[bhnautika]

Stu I have a bit of experience with maxsurf and other cad, I also have a little time on my hands at the moment. I might be able to help out.

[lazeyjack]

thanks people, Take delftship(free) I can not bring up the pink comb that smoothes lines, hightlight the line to purple, click curve, the feather does not appear? any idea, I will try post the file

[lazeyjack]

see the flats, I follow tute but can not bring up that pink feathered comb

[raw]

I just took a look at the dxf. Whilst I am not conversant in delftship, it looks at if your surface is defined as having straight sections in the longitudinal direction (hence the flats). In this case, there is no curvature, and thus you will not see a porcupine graph.

In maxsurf/rhino, this is fixed by looking at the longitudinal "degree" of the surface properties. Degree 1 is linear. Anything above will give curve. Degree 3 cubic splines are pretty common and usefull for most applications.

Again, I'm not familar with delftship per say, but this is where I'd be looking.


brett

[lazeyjack]

G,day,
i found the porcupine as you put it, but its so hairy like all over the page, the flats seemed there by default, no matter where you drag they are present
I sent you a pm, ?
two days ago

[raw]

I replied to you by pm 10/4 on tuesday. Did you get it?

I'll have to have a play with delfthip a little later to see if I figure it out. I'm not the best person on that program unfortunately.

[bhnautika]

Stu the model in dxf seems to be made up of panels, which are going to be impossible to fair. Is this the sort of thing you are after, its three surfaces in Maxsurf.

[lazeyjack]

yes it is a two chine yacht based on Robert Clark Design, I jave the original dwgs from 1970,s, my mate sailed this boat around the Horn, very stiff she was
i figured I must fair each line separately as it is they all show at once, I just gte so frustrated but I,ll keep on til I get it I do have maxsurf but cant seem to exprt it there Thank you v much

[lazeyjack]

0oh I see, DUH I have made all the body sections, creases!! duh!!

[lazeyjack]

ok, I,m sorter sorting it, another question,
If I open a default file, and I want more depth to the hull, like more rocker , then the default comes up with a very high wooded topsides, in other words all is out of reasonable proportion. So if I type in Depth, say 800mm, the freeboard is nearly 3m, If I enter from (new) depth 500mm, then all is in proprtion, my question, is there a way of holding these acceptable proportions but increasing the hull depth? thank you, another day at the coal face, but beats plating a steel boat I guess

[bhnautika]

Stu there is a quick way round your problem, create your default boat with a 500mm depth, then go to the project menu – project settings- main dimensions, then change the draft to 800mm.

[lazeyjack]

actually I stumbled there by mistake, but it wont alter the wl measurement of base, so I will have neg values from base in offsets, er um that is when I learn how to find the offsets, thank you:))

[lazeyjack]

what I meant to say is, on the plan, I will be stuck with 500mm, and same base, the profile will hang below base

[bhnautika]

Stu I think offsets are in the export menu

[lazeyjack]

thanks mate, found, trouble is get ID 32 error when I try get the file into Maxsurf,

[bhnautika]

Stu what file type are you trying to get into maxsurf and why! Offsets are a text file.

[lazeyjack]

I have the offsets now, the hull is complte but now she needs a deck and a house and frames, cant do that is Delft, freeship?

[lazeyjack]

stations 600, by default suits me, I will use heavy plate, 8mm topsides, 10 bottom, 6 deck, two girdars , and no stringers. Integral tanks, water/ fuel/vodka

[bhnautika]

Stu I found hull surfaces (only one side) transferring as iges files move across reasonably well to MS from freeship.

[lazeyjack]

Stu I found hull surfaces (only one side) transferring as iges files move across reasonably well to MS from freeship.

ok, well can you pm and leave your tel number, will call tomorrow, actually this eve I am slightly embibed, unfortunate to say with local wine and not the delectible, Vodka from Siberia, that I have become fond of. AAHHH those Russian skippers, such pro mariners, they do not give their quals out with every 100 bottles of coka cola!! even seamen must spend year in school.

[lazeyjack]

Stu I found hull surfaces (only one side) transferring as iges files move across reasonably well to MS from freeship.
ok sorry I did not see this post
When I try open with ms, it comes up with 32 error, anyway I found I can do much more IN Delft than I thought was possible
can you tell me, I,m on the deck now, see big strides for me:) can you tell me how to do this, ok, I put in points along the plan of the deck, , how do I link these points to make a control line, I have the deck, c/l which is just a moved edgeline9sheer) and am doing the lines 1/3 beam out and 2/3 beam out
thanks
Stu

[bhnautika]

Stu did you get my PM? I think freeship see surfaces as separate panels so I think you have to split the deck surface at each column.

[lazeyjack]

open a new design , make edges as for chine boat and then how to you assign those plates, chines, bottom, etc to a layer please?

[Bruce Taylor]

First, create some empty layers: Edit-->Layers-->New . Repeat, as necessary, creating "layer 1," "layer 2," etc.

Notice that you can now change the "currently active" layer (the one to which all new work will be automatically assigned) to one of the new layers, simply by clicking on the little drop-down layer menu on the right side of the lower toolbar (which by default will probably read "layer 0") and clicking on one of the other layers ("layer 1," "layer 2", etc). The new layers you've created can be given names, if you like..."transom," "deck," etc (click "Edit-->layer-->dialog"). Each layer can also be given its own colour: click on the little square beside the layer item on the toolbar (by default it will be green), and select a new colour from the popup colour palette.

Now, turn on "interior edges": Display-->interior edges. Select the face you wish to assign to a new layer.

Change the "currently active" layer on the toolbar to that layer, and deselect the face. It should now have been reassigned to the new "currently active layer."

[lazeyjack]

thank you Bruce
I can never understand you they dont spend more time writing what you just did in their manuals, I have spent hundreds of hrs just guessing
ok I will give this a worl .
as it is I saved say the deck as a part by deleting everything else but the deck, then imported it back in ok, but it dropped the import in lower than the original postition, it is all very frustrating
Like if I was teaching how to loft a boat the old way, i would do a heck of a lot better job with an apprentice than these programmes do for me and thousands others
i spose its ok if you have been raised on a CAD diet from school, uni whatever, but i WOULD SURE AS HECK SHY OFF BUYING MOST, I found the McNeel guy at rhino the best for help, he must be very busy but he replied to the most basic of questions!!
thank you again, muchely

[lazeyjack]

got it figured Bruce thanks

[Bruce Taylor]

Glad to hear it.

If you have any other questions re. FREE!ship/DELFTship, post them and I'll see what I can do.

[lazeyjack]

very kind of you

[lazeyjack]

things plod along ok, But now for some unknown, the co -ords which are normally visable at top pf window, when one moves mouse, are not there, they are only there in the 4 small windows, body, pr, plan, etc>?
also the displacement is missing from the "design hydrostatics result --any ideas
Stu

[Gilbert]

If your file name is so long that it fills up the top text bar the coordinates are off the screen somewhere to the right (in cyber space maybe). If that's not it I don't know why they aren't there.

[lazeyjack]

nope not long, sometimes they are present, like GW, sometimes they are off in Cyberspace
spent lot of time WA, should be part Can:))

[lazeyjack]

very kind of you

Upon (desIgn hydrostatics, IN Delft, there is no displacement? any ideas anyone, thanks
Stu

[bhnautika]

Stu Try this have a look in the project menu, project settings, main dimensions, draft and move it down a little.

[lazeyjack]

BILL HOW ART THOU
All it was was a leak point in delft all the cl points must be zakkly on the 000mark

[bhnautika]

Fine thancks f’asking did you get my Email .re software

[lazeyjack]

oh sorry yes, thought I replied, I got so bogged here, and alone cooking for boys, this that Helen in Europe etc, then lost all yesterdays work and getting mad a hell with Billy doc in the forum on metal boats, wants to plate a double ender only 40 feet long in 13plate, he is a mate, and he simply will not be told:))

[Bruce Taylor]

Bring up the Perspective view, and turn the boat around so that you're looking at it from behind.

Hold down the control key while selecting the points all around the transom, one at a time, moving in a counter-clockwise direction.

When all the points have been selected, click EDIT-->Face-->New

You now have a new face at the transom.

You'll notice that the edges around the new transom are no longer "creased" (they won't be highlighted in red). To restore the crease, select the edges, while holding down the control key, and click EDIT-->Edge-->Crease.

[lazeyjack]

you are a stalwart, always come to my rescue, and do I just split the thing to make a radious? draw beam on the ground give it R say 5m and then enter those measures into the model, they would all be x minus?

[lazeyjack]

i did it all delft then found delft free does not allow printing of Pl developements, so had to transfer the whole thing to freeship point by point as I could not export to freeship, I think its in my pc this glitch

[lazeyjack]

um tried that finished up with ball of knitting?

[Bruce Taylor]

The order in which you select the points is important. Start anywhere, but move around the transom in an orderly counter-clockwise manner.

DELFTship should save to FREE!ship format. Click "FILE-->Save As", and down at the bottom of the dialog box you should see the option "Save as Type". Select "Version 2.6" (or whatever) and your FREE!ship should be able to read the file.

(It crosses my mind that the free version of DELFTship might not include the "Save As" feature...I'm not sure.)

[bhnautika]

Stu I now know why your files would not open.

[lazeyjack]

Stu I now know why your files would not open.

I,m all ears?
And Bruce I managed to open yours
weird
Case you wish to know why I,m working on this simple hull, well a mate sailed her round the Horn in 1980, she was 9.707 m, Robert Clarke Design for him, she did not rolla at anchor, and he could not put the rail under Flush deck small house aft, She self steered all the way all around the world
'I thought oh well, make her longer wider, she will have a bigger resale market if I ever build, I,m tired fancy complex boats, i just want to get back to basics, like reallbasics, although I want the best sails, , powerful winches, and scheel keel to limit the draft for this coast

[Windvang]

Sorry Lazey, could't resist messing about with your virtual girl Kate. :)
Maybe you can get some usefull tips from this version.

[Gilbert]

I have seen a few Robert Clark designs over the years and have liked them pretty well.
I spent some time looking at the Kate2 file and the original katebest23scaled1-1. I am very impressed with the buttocks and diagonals of the latter. I can't say that the shape above the second chine impresses me but I guess you have to give up something to have beautiful buttocks and diagonals. And if it has the great behaviour you describe, well, we'll just have to get used to the topsides. And as often happens the look of the topsides may be more agreeable in person than in the drawing.

[lazeyjack]

thanks al of you, i will see if I can open the file windsong sent
Colin Quilter had Robert Clarke do Kate, his brother was Peter Blakes navigator on all the whitbread races, and also for others on Volvo classics Mike started a 22 footer in which to sail around , at the same time, but never finished her,
Colin said kate would reach abt 10 degrees heel then become stiff really stiff, he said that the harder in blew the better she sailed
I originally looked at the omni design, but the flat slamming bottoms put me off
have you heard of the schooner Carita, 180 feet I think she was, a superyacht before the word came into vogue, Clarke designed her in the fifties I dont care abt the topside panel, I will airbrush it with say an Orca smashin through the plate or, -- any suggestions:))

[lazeyjack]

here is Kate, I think somewhere near the Artic circle

[lazeyjack]

Sorry Lazey, could't resist messing about with your virtual girl Kate. :)

Windvang thanks you got the hollows out of the WL,s and faired the deck, , I,m a bit worried now, I had permission , but if the Clark estate saw her her I would be very embaressed I think I had better remove her from my posts!!:!:

[Bruce Taylor]

Stu, I've edited the file out of my post.

[lazeyjack]

Stu, I've edited the file out of my post.

this place is full of gentlemen, thanks Bruce

[lazeyjack]

seeing as how we are talking abt Robert Clark maybe this pic should be here

[nero]

Lazeyjack,
You are making me feel sad. If only you had stopped by Marseille, on last years voyage, you could have found the simple way to design.

Well maybe next year! By that time you may be fluent on the other software. smile

Hey!! I came past Marseilles in March and I had lost your contact detail;
meanwhile I still dont have your numbers as the pc crashed, how are you!! write to me please

[lazeyjack]

can you tell me how I open a freeship file in Rhino Pleaseeeeeeee

[Raggi_Thor]

Export as Iges?

[Raggi_Thor]

Jack, did you get my email?
I was worried about your laughter!
;-)

You now have a new face at the transom.
in freeship, holding control key selecting pts around transom, there is no face in edit but face stands alone, click face, new, nothing happens, tried a 100 times?

tried this, actually yes you can save into freeship, but you cant open in freeship, says not a valid file, others have tried too, I suspect it is becuz they want you to buy the pro version

[bhnautika]

Is this what were after, select all points from sheer down to fairbody (pic01), then go to FACE>NEW (pic02). Then select all the edge lines. Then up to EDGE>CREASE (pic03), deselect all. Then select the opposite edge line, go to EDGE >SPLIT (pic04), deselect all, select new point and in the dialogue box, tick corner box, then move point to where you want (pic05).
