Cut Question

I have a wall, and i want to cut a hole out of it for a window. how can i do this?

Hello there...rez a box hollow it out but change the hollow shape (it's the drop-down menu under hollow) to circle,flatten it, rotate, and expand it to the size you need!

Might just be better to use a texture to create the window instead of an actual opening. The method above is a fixed hole that u cant move about unless u make a wall out of seperate objects.

You can use 'hollow' to punch a centered hole in the top surface of a cube prim, and that hole can be rectangular, round or triangular. It is always centered, and always goes the full distance, top to bottom. Adjusting the percentage for "hollow" makes it larger or smaller. Zero percent is no hole, 95% is as big as it gets. So if you flatten the cube's height to the thickness you want for your wall, make the other two dimensions the width and height for your wall, and rotate the prim so it's on edge instead fo flat on the ground, you have your wall with a hole in it.

Needless to say, this is rather limiting. You can not pick a random place on the wall, pick a random shape, and punch a hole in it wherever you please. SL does not do boolean subtraction of prims. Much though builders would love to have that feature.

An alpha-mapped texture can make the appearance of a randomly placed hole in a wall, but also has limitations.

* An alpha-mapped 'window' placed on one side of the wall does not automaticly line up with a 'window' placed on the other side. Depending on the prim shape used, aligning it precisely can be a pain.

*Alpha-mapped surfaces are subject to the 'alpha sort bug'. This means that a partially transparent surface, like a shrub or your prim hair, may appear to be 'on the wrong side' of a second nearby alpha mapped surface on some other prim. Particularly annoying when trees or bushes are near your wall.

* When you look through an alpha-mapped window, the wall appears to have zero thickness.
