I've seen anim8or... but is there ANYTHING like it for macs?

As far as im aware development has stopped on the skp viewer, dont really know anything more about it than that though.

SU7 date: the eternaly asked question, its just a pity there is no answer.

Gaieus once mentioned a free programme called Camstudio. seems to work quite well...

as far as I know they enable you to determine the inner side or outer side of a shape. just imagine you have a cube. how is the computer supposed to know, what is inside and what is outside?
some years ago everyone in europe believed earth to be the centre of the world until a smart guy called Kopernikus found some convincing arguments that the sun is much more centered than our small blue planet.
two sided faces are our arguments to define the orientation of a shape. for basic SketchUp use this is not that important. but if you start rendering a scene it is essential.
if you have a glass object for example, light will change its colour depending on the distance it travels through the material

therefore the render engine needs to calculate the thickness of the object. and it can only do that if it is told what the inside of the object is and what the outside.

There is FlightPath (free) and its commercial, more advanced sister, Fight Path2 or even (the also commercial) PresentationBundle that can do that and even much more (more exactly you can set the path prior to the scenes and allow your camera to move along).

Hi Yaakov,

It is very important to set the gluing plane correctly. To do this, when createing a component, there is an option to set the axes. When it's a "glue-to" component, there won't be a z axis for it (just a blue cross) but setting the red and then green axes correctly on the plane you want to cut the opening is essential.

As a quick workaround to make life easier, I usually start making my glue-to/cut-hole components on a single, vertical plane (using it as a drawing board) and in this case the gluing plane tends to be created on this plane and I don't have to manually set it.

yeah, some more modifier keys would be really cool.

some examples:

Move Tool:
press Shift+Ctrl to break a line at the cursor point (so if you hover over the midpoint of a line, press these keys and move upward, the line is broken and connects the endpoints and the altered midpoint)

press Alt+Ctrl to do the same, except that an arc is created instead of simply breaking the line into two

that would sometimes really fasten up some operations.
