While the object editor built into Second Life is good, and it’s been getting better, if you have used software with 3D content creation as the primary goal, you would find yourself limited by what you can do in-world. These are great tips, I’ll try to match each one with a SketchUp function (well it’s easy).
Tip 1: Alt+zoom – scroll wheel in SketchUp.
Ctrl+Alt+click – hold+move middle mouse button in SketchUp
Ctrl+Shift+Alt+click – Shift+middle mouse button in SketchUp.
I think that’s much easier to do. I have trouble switching from one to the other, always try to orbit using the middle mouse button in Second Life.
Tip 2: Move objects using the Move tool. In SketchUp, pick a point on a Sketchlife prim, or anything else, click on it, then the prim will move with the mouse. Click on another point anywhere to move your object such that it snaps.
There is also a Rotate tool, and a Scale tool in SketchUp. Hot-keys, such as M, R and S can be assigned to them.
Tip 3: Very easy to position cylinder to be exactly in the centre, in SketchUp you can snap to midpoints.
It’s Ctrl+move to copy in SketchUp.
Tip 3a: Hold down Ctrl when using the Scale tool to resize uniformly about centre.
Tip 4: The grid is not necessary in SketchUp, because snapping takes care of all alignment.
But you can also make guides if you want a grid.
Snapping is much better, because you are not limited to the grid point resolution – you can snap to any point anywhere.
Rotating in SketchUp snaps to 90 degrees, and all common angles.
You can also snap in only one axis, which is great for aligning: you do that by pressing one of the arrow keys on the keyboard while moving an object: the motion will be restricted to one direction.
Tip 5: Rotating in local or global coordinates can be done by placing the Rotate tool on the appropriate surface, picking the axis of rotation.
In general, snapping eliminates the need to switch between coordinate systems: you can snap any point to any other point, which include end-points of objects, mid-points, arbitrary points on edges and faces.
Tip 6: This is done using Rotate and pressing Ctrl in SketchUp.
Tip 7: In SketchUp, you can not only place a different texure on each face, you can also drag the texture on each face, and precisely position it. The texture can also be rotated and scaled. Moreover, you can projectively copy textures from one object to another – for example, putting one texture image over several adjacent prims is easy.
Tip 8: Putting a fully-transparent texture is easy using the paint-bucket tool.
For the tip, I also recommend putting the Transparency to 90, because the fully-transparent texture takes time to load.
Tip 9: Sketchlife links imported sets of prims automatically.
Tip 10: Create-copy is also something covered by using the Move tool + Ctrl in SketchUp. You can clone any number of currently selected objects in SketchUp.
And it is possible to snap it exactly, whatever the dimensions!
So, to summarise, another option for builders, better in many ways than modelling in-world, is Sketchlife, first launched in July 2009. http://vrshed.com/sketchlife/index.html
