Hi there everyone around,

first of all, please excuse my english, actually i'm from germany.
My problem: i've created some curves after a blueprint and i want to put those curves together to a surface,
but i don't know how. I've tried Blend, Network and Loft and nothing worked or created a totally distorted surface.
Do i need some more lines, or how can i manage that?

Here are the curves:



Because i'm using the free version i can't save and attach the scene so i post the blueprint also:

And here is the blueprint:



If you find an answer for my problem, it would be nice if you could explain to me how you managed to do that so i can learn from you.

Thanks alot in advance and greets from germany :D

EDIT: here is a picture of what the surface should look like:

......interesting

Try posting the curves then someone can actually help you properly ;-)

Aloha Paso!

NURBS are great! Probably what you may want to try there is to:
Seperate your top profile curve up a bit.
Then extrude your base curve up higher than the desired thickness of the guitar body.
Then sweep your profile curve (Guitar face) into a surface. (You could make a better face for this than you show to produce a better surface with this method.)

Then place that surface at the desired guitar body depth and boolen diff to create the shape you want.

Good luck.

HI Pasolein here is picture this may help you

Here's a file so you can visually see what I said.








These curves are very random as I just did a draft trace of your posted picture. If you use the original curves (remove any corner points) and create a profile curve for the face that is "smooth" with no corner points, this should give you a nice surface to cut the base object with.

Good luck. (Rammstein or what?)

Your english is good.

Hi there,

wow you are fast!
thanks alot for your quick answers.
you helped me alot.

@BurrMan: I've try'd your way first, but thats not exactly what i wanted. but thanks alot anyway!
@lyes: I'm gonna use your method, i have to put in some mor cp's and change the shape a bit to achieve my wanted look,
but thats ok.

this is what i've got so far:



like i said, the second method is better but i have to tweak/put in some points.

Guys you are great!!!

!..! (]o.O[) !..!


oh and BurrMan: yes im into rammstein, ive seen them live and ive met Till the frontman on the streets in my hometown.

EDIT: please take a look at the attachment, thats the shape, but how do i get rid of those yellow lines?

This was just using network. I am surprised that the area marked on the MoI screen shot seems to render out without problems?

>>please take a look at the attachment, thats the shape, but how do i get rid of those yellow lines?

Those lines are from your construction method. Corner points tend to slice up the surface. So from your original curves, are there "seperation" points there? (Two curves joined perhaps)

If you look at the original curves and turn on show points, you can add a point on either side of those 2 points and then delete the two at each end of the line. Then when you create your surface it should be clear.

I think you may get a better/clearer answer here in a bit.

Hi Paso,

Is there a reason why you want to get rid of the yellow lines?

Those are edges of surfaces that you have created - it is not an error to have edges, edges are always present on every surface that you create.

For closed surfaces it is normal for there to be a "seam" edge where the surface is closed.

NURBS surfaces are kind of like rectangular sheets of rubber. The sheet can be stretched and pulled in different ways, but to build a closed surface like a cylinder that is done as if you had taken a sheet of paper and rolled it up so that left and right edges were meeting each other. There will be an edge displayed in that area, it is a natural part of the surface and not an error or something that you need to get rid of...

For some kinds of construction methods you may get edges in areas where you use curves that are made up of multiple segments.

If you want to reduce the number of edges in cases like that, you can merge segments of your curves together by using Edit/Show pts to turn on control points and then select and delete the point where 2 segments are touching. That will fuse them together into a single segment.

A segment is one piece of a curve, like for example a rectangle is a curve made up of 4 line segments. You can use the Edit/Separate command to break a joined curve into individual curves for each segment, then they will select individually so you can see the segments that way.


But in general it looks like you have created your shape successfully and you should not really worry about those yellow lines unless there is some other problem with the shaping of the surfaces in that area.

Hi all may be here is better way to do it !!!!!!

Seems there is a view missing on the Blue prints ;)

Hi, There are several solutions to model this.
For a violin project, I lofted several cross-sections and then projected the top view.

Its a boy!

More than one way to skin a cat.
(Acknowledging that this may not be "sound" correct guitar making theory?)

Firstly, I created a slice off the top of Sphere. Actually a rotated arc.
Then extruded the Guitar profile and did a Boolean intersect.

I could cry with the simplicity!

Just a little progress report.

Grab a beer and your AIWL hat and rock!

I did! I did!

Just a quick render to celebrate my birthday--EVERYONE is expected to respond!

-----joke!

I have fun!

Brian

veery nice brian happy birthday how young are ua 61

Thanks

Just a young 76 (Or is it 77----well something like that!!)

It's all in the mind you know!
