Here you go, Jack.

The best time to group or componentize objects is before they get stuck.

If you do get something stuck and don't want to group it just to break it loose, you can get it back simply by moving a copy and deleting the (stuck) original.

~Voder

On the occasions when the lines just sit on the face without cutting, is it possible that the object you're intersecting is a group or component? You can't get a complete mutual intersection between two objects unless they're in the same context, meaning they're either in the same group or component or none at all.

I'll give you a clue, it is a top elevation...

Terribly sorry, Remus, but "top elevation" is an oxymoron.

~Voder

Apparently you failed to sample the striped texture from the flat face after making it Projected, notwithstanding that you included that step in your written description.

~Voder

Read about the Position Texture tool in the User's Guide.

They appear to be pairs of endpoints butted up against each other. Apparently there is a break in the line you used as a path for your Follow Me operation.

It would seem that you have Endpoints turned on in your edge style settings (Window > Styles > In-Model > Edit > Edge Settings. To get rid of them you could simply uncheck the Endpoints option. If you like the appearance of the Endpoints effect, you can knit the broken lines back together using the Ruby script repair_broken_lines.rb, which you can download from this page.

~Voder

Which context-menu commands are you talking about?

~Voder

Tina,

I don't know how the guides (construction lines) on your model changed color by themselves, but if you want to change their color to something else, say, red, you can do so by going to Styles > Edit > Modeling (the last icon).

You sure gai? i had a quick go at modelling it and couldnt see anything funny.

Remus,

That's because the extrusion doesn't double back on itself. Try closing the circuit and see what happens.

~Voder

Notice that Puck uses the same radius along all three axes in his model. Remus's solution, however, uses a different radius on the vertical and horizontal edges. If one uses the same size radii on all three axes with that method, it results in a defect in the surface, which has to be dealt with.

Bubba Love's method is cleaner and uses consistently sized radii, but it produces an odd point at the corner instead of a smooth spherical surface.

The following tutorial shows how to repair the defect resulting from the first method and also shows a third method (presented first) that doesn't seem to have any serious issues at all.

Just move a copy of the whole thing straight up by 12 cm and then connect corresponding vertices with vertical lines to form the fascia surfaces.

Actually, they are. I happen to be a hobbit.

Where'd you get the trees, do they render well?

Peter,

Those are tomsdesk 2.5D trees, which you should be able to find on this site. (thanks, tomsdesk.)

I can't say how they render because I haven't tried it. Frankly, 3rd-party rendering apps don't interest me much. My personal opinion, which I understand is not the majority view here, is that a static 2D image is a poor substitute for a dynamic, interactive 3D model, and my efforts are simply not directed toward producing 2D images. The images I've posted here represent pretty much the extent of my experimentation with 2D output from SU.

Thanks for the interest,

~Voder

Christouille,

Can you upload a model exhibiting these problems?

~Voder

Maybe one day I'll even get it built.

~Voder

To reproduce the effect I depicted above (which is a series of circumferential rings running all along the bent cylinder, and which consistently gives that appearance from all angles), paint the texture with the stripes turning through a bend onto a vertical surface (a rectangle) that is lined up with the bent cylinder itself, just as I have shown. Then right-click the rectangle and select Texture > Projected. Then use Alt-Bucket to sample the projected texture, and finally click on the bent cylinder with the Bucket tool.

See attached.

Sure, Taff, if you want to add emphasis on "around," be my guest, but one could just as easily add emphasis this way:

...so the lines wrap around the cylinder all the way through...

As I said, CurryPork could have done us all a favor by selecting his words--and his picture--with greater care.

At this point, I guess we could either assemble a panel of semanticians, cryptologists, and empaths to try and unravel this mess for us, or we could simply say we gave it our best shot and walk away from it, with no cause for shame.

I vote for the latter.

~Voder

Remus,

My apologies. If using projected texture this way is what you were talking about, then it does indeed seem to work. Very clever idea: my compliments.

And Taff, it was real quick and easy.

~Voder

Taff,

I'm afraid the tedious method you describe is the only way I know of. Luckily, I thought, that wasn't what CurryPork was looking for, judging by his image and phrasing of the question.

He certainly could have made it a bit easier for anyone trying to help him, first by posing his question with greater precision, and second by providing the texture itself to work with. I'm embarrassed to say I wasted about half an hour just looking around for a stripe like that (unsuccessfully).

Remus, I'm extremely skeptical about your suggestion of "bending the texture" in PhotoShop, but I would be very glad to be proven wrong. Please show me.
