[Tutorial > Texturing] Texturing an arch - #2

Gaieus

You need to have slicing off (right click after selected Radial Bend of Fredoscale)

or you can enter the "fine tuning" dialog by pressing the TAB key then.

Very good.
thanks a lot

My first post. Thanks a lot, as new user, SketchUcation is my first learning resource. I have SU 8 pro.

I am trying hard to understand how texture archs. My model is a roman villa near Palencia (Spain) I want to model.

Until now I cannot get any results. I have downloaded the UV.skp file that Massimo send to Gai. The workflow was:

-load UVmassimo.skp
-hidden geometry off
-select face with textures , one click
-remember UV
-fredo scale and bend 90º
-open the group fredo scale has made, select face with textures, one click (hidden geometry is off)
-restore UV

Nothing happens...the textures are again horizontal.

Another thing I dont understad how to build the vertical column before bending. Reading the thread, it seems that you have to create a bloc, texturing-bricks, stone, whathever-and then copy and add pieces until you have the whole column you want to transform in an arch. I have done so, and my blocks do not macth and after CTLR+delete to smooth the inner lines of separation I cannot select with one click the whole surface to aplicate "remember UV".

Please, could anyone tell me what I am doing wrong?

Hm. I am not sure what you are doing wrong. Make sure however to completely turn off slicing in Fredoscale (see the post above). The reason is that UV Toolkit can only remember UV co-ordinates on the exact same faces it remembered them from. This means you cannot introduce any new faces otherwise it will not work. The number of faces must be the same before and after the bending.

For this same reason (and to be able to bend the column), I had to copy all your divided edges onto the other three sides as well.

You can turn off hidden edges afterwards under the View menu. But you can just select all and do the bending and restoring this way.

Here is your (half) arch. You can mirror it to get a whole.

Ah, by the way, when we are at Roman villas in Spain... I took part in a EU project that also involved one in Fuente Álamo (Puente Genil):

You can use QuadFace tools: http://forums.sketchucation.com/viewtopic.php?t=39442
Check out the videos for how to UV map.

Thanks a lot, Gai and Thom. The slicing off did the job, now I can bend the bricks and builid archs in my La Olmeda model. How could we newbies do anything without you the masters?

Gai, if it happens that you come to Spain to see Roman villas or whatever, drop me an email-hope that you, as moderator, can get my email. Please note I am in Palencia, with P (people get confused with Valencia, with V).

(both in Spanish, sorry!)

Gaieus

That's quite a villa indeed!

The first link did not work at all but the wikipedia page also exists in English: http://en.wikipedia.org/wiki/La_Olmeda

juanfernandez

The first link is OK, Gai. The web administrators, I don't know why, shut off their web sites by night, and turn on then early in the morning. It's a provincial institution-Diputación Provincial in spanish- and they have this weird way of publishing their web sites.

Gaieus

Yes, I can see now... "Reconstrucción Virtual > Próximamente". Is this what you are working on?

juanfernandez

No, I am a newbie, and cannot take that job by now. I am a teacher, we plan do educative software and documents related to the Olmeda Villa. My 3D model is may way to learn SU with a motivating subject. Perhaps in the future I will be able of making something worth of the Villa.

Gaieus

Get me to do it then. I am an archaeologist, too.

juanfernandez

Ok, Gai, I'll take your word.
When I became profficient enough in SU to do the job, I'll call you. I have to work hard in SU. Then they have to let me take photographies and measurements of the Villa. I think there will be no problem, because I am in very good relations with the Villa's provincial managers.

Thanks guys! Thanks for the tutorial and the tools!
Just saved me with this huge arch for an addition, which matches a design done 10 years ago on the same building.

BTW - I didn't read past the initial steps since I didn't have any issues, but if you are matching an opening - make the height of the flat column of brick equal to the length of outer arc of the assembly. Did that make sense?

Gaieus

Nice arch!

Of course, now we have Whaat's SketchUV Plugin (with tube mapping) which save even more time and head-ache...

I guess it all depends where you grab that column (inner or outer side) with Fredoscale.

ziiar

Is there a way to do this without the FredoScale plugin? I'm making a gothic arch like the one mentioned in the previous thread:

I assume this was modeled with the follow me tool, which is what I did do model it.

thomthom

This wasn't made with FredoScale nor the Follow me tool.

I drew the outline, then offset to make the inner hole. Then another offset to create the line in the middle. After that I selected the edges of the inner hole and moved it inwards.

hm... this is probably better suited with screenshots....
