project curve to a sphere

[sendhil_84]

Hi,
I have a project, creating globe. I cant wrap the map which i draw, over the sphere. Pls help me..........

With regards,

can you set up the map on a plane and project it onto the sphere surface? The map is an image or a set of curves?

its set of curves,extracted from autocad.

I believe you can only wrap on a cylinder. Sphere....I have my doubts.

 

[SRINIVASANIYER1]

tHIS IS WHAT PROE HELP SAYS....
<H2>The destination of the wrapped curve must be developable, that is, some type of ruled surface. Pro/ENGINEER automatically selects the first available destination. You can select another destination, if desired.</H2>

I selected thesurface particularly which i want. But it wont to wrap it. Is any other way to build it using other than wrap feature? I stucked with thisfrom yesterday........

 

[wsylvester]

do you havea sketch csys?

 

[wsylvester]

hmm... doesn't look like wrap will do it...try project

 

[trillicomm]

how detailed does the globe has to be? is it not to scale? just symbolically I assume

 

[sendhil_84]

Here i attached the image of Globe which i recieved from client. It will showhow it has to be. MapShould be 2mm deep from the globe.


Still i didnt get any idea. I tried with sketch csys too. But no result. If anyoneget any idea, pls share with me...

I have an idea, not sure it will work fast, this

use Decal to project the image onto a solid sphere, adjust X-Y,rotation to fit best

then trace the map curves by using Style/Curve-On-Surface as best as you can

create surfaces to those closed curves

thicken the surfaces, positive or negative.

a better idea is to find a picture of FLAT AND STRETCHED GLOBE then wrap or project on the sphere to get the true proportion...

thank u. I will try your method.

even u dont need to project the sketch on sphere. just use offset tools and choose with draft option and it will make u so happy.

what a GREAT IDEA zaki, now we need to sketch the real Africa..I think using Decal can help.

Hi Sendhill, (what is ur name exactly??)


Didnt u use offset dommand ever?? set ur selection filter to geometry>select the surface of globe>go to edit>choose offset>go to dashboard options and choose with draft> make the sketch > may u select the direction plane after finish the sketch.

but the sketch must be on a datum plane or surface, or u can say the curve must be sketched curve.

Hi zaki,


My name is sendhil only. Thanks for your detailed reply and sorry for disturbing u by asking like this silly questions. I dont know how to use draft in offset feature and i didnt used it before. Thats y i asked u to explain. Ok Thank u,
