Archway

I have a wall built from a cube - I now need to insert an 'Arabian" looking archway door into it - how do I do this (or can I?)

If there is a tutorial I'd be interested - I went to the excellent Ivory Tower Prims tutorial and was surrounded by examples of what I want but not how to build them.

Is there a way to 'difference' or 'Subtract' between two intersecting prims?

Tarak?

Not sure what type of "arch" you're talking about. Is it more pointed near the tip?


If not and you just want a half circle arch, you could hollow a square prim and change the type of hollow from a square to a circle. Then make cuts to the prim so you'd have the top section of your door. You would then need to create the rest of your wall by using two prims...one on each side. The two wall sections on each side of the door could also be hollowed some to create windows. Total prims = 3

thats the most "efficient" way to make it. Obviously, you can be more elaborate and build your doorway from prims.


There may also be a door texture that you could use on a plain prim. You'd have to then make the prim phantom so that you could pass through it. And to keep people from walking through the entire wall instead of just the doorway, you could sink thinner prims into the wall section below the surface....these would NOT be phantom. Total prims = 3

There are many talented people on these forums and I'm sure they may have other suggestions for you.

Good luck.

There is no 'Boolean subtraction' in SL building. No way to use intersecting prims to remove part of one prim with the presence of another.

Arches have to be built from pieces.

The most simple arch, and the least control over its shape, is a single rectangular prim, cut to 0.25 and 0.75, and hollowed to 50% or so. If you started with a square, that gives you half a square with a notch cut out of the bottom. You'll need to rotate it and streach it to make it the shape and position for a usable 'arch', but the usefulnes of this type of arch is severely limited. It's best used only to make the wall area around a more complex arch.

A round topped arch can be made in a similar manner, by using a round shape for the hollow in the prim, and then standing this rectangle with a half-circle bite out of it on top of a pair of posts.

But for an arch with a pointed top, you will need at least 4 prims. Two will be the sides. The other two start as a square prim with a round hole in it, and cut at 0.25 and 0.50. That gives you a quarter circle bite out of one corner of a square. Play with streaching this, and make two and put them together, and you can make the top of a pointed arch.

Go back to the Ivory Tower, and actually go step by step through the examples, there, reading the notecards carefully. They do explain this quite well.

Thanks people - excellent replies - I'd managed to make one but it was quite messy and too 4-5 prims - back to the drawingboard equipt with you suggestions - thanks again

Hiya - I don't know if this is quite what you're looking for but I recently remodelled my house to have an arabian/indian/turkish/anything-pretty-I-felt-like-adding theme...

There are some arches outside (with trellis-like inserts) that might help - also a simple arch on the inside between the living area and bedroom. You're welcome to have a look if you like (everyone else seems to! Excuse the 'be polite' greeter, there's been a huge influx of newbies just wandering in recently) - just click and select 'edit' and you'll see the parts they're made from. Not that I'm saying I have it right, just that this was my solution. Riiki 151, 76, 26 ish

Edit: Oh, or search for 'Nectaris' and it's the squareish house to the north.

I've attached an image I made of where the usual cut positions are. Perhaps this will be of assistance to you.

Thanks people for the generous offers - I'll take a look over the weekend - thanks again.

One way I could foresee doing this would be to create a texture to apply to a box that had an alpha transparancy channel to it that had the shape you wanted for the opening. Then make the box phantom so you could walk through the invisible part. (of course you could also pass through the implied solid part). Then create a second texture and object for the door itself. only don't make this one phantom.

Love to hear how you make out.
