Editing prims


Use the Build window to move, resize, rotate and otherwise manipulate inworld objects.

 Checking Snap to the grid in the Build window forces you to position objects on a grid. This is helpful in making sure that objects line up correctly and are precisely spaced.


  • Right-click an object and select Edit. This opens the Build window to the Object tab.
  • Choose Move to enable the Position function.
  • Click and drag the red/green/blue axes on an object to move it around.
  • Clicking on the red (X), green (Y), and blue (Z) arrows lets you drag the object only along those axes.


  • Right-click an object and select Edit.
  • Choose Rotate in the Build window to bring up the rotation sphere.
  • Click and drag anywhere within the sphere to rotate the object freely along all three axes.
  • Click and drag a specific ring (red/green/blue) to rotate the object only around that axis.


  • Right-click an object and select Edit.
  • Choose Stretch from the Build window to bring up the sizing box.
  • Click and drag one of the white corner boxes to scale the entire object proportionally.
  • Click and drag a red, green or blue box to re-size a prim’s length, width or height (respectively) without changing the other dimensions.

If the Stretch Both Sides option is checked, the object’s opposite corner moves in the opposite direction. If Stretch Both Sides is unchecked, the opposite corner remains in place.

If the Stretch Textures option is checked, the object’s textures are proportionally resized together with the object. If unchecked, the textures retain their original size. This means that if you are increasing the object’s size, the textures repeat rather than stretching to fill the additional area. If you are downsizing, you will see only as much of the original texture as fits on the smaller object.

Entering specific values

Under the Object tab (shown above), enter specific X, Y, and Z coordinates to move, re-size, or rotate the object. Changes to these values are always based on the center of the object (the point where the red, green and blue axes meet)

Advanced edits

The Object tab offers several additional options for editing basic prim shapes. Here are some common examples:

  • Path Cut (begin/end): Takes out a slice of the object along its Z axis. You can specify where the cut starts and ends.
  • Hollow: Puts a hollow center in the object starting from the center of the shape and expanding out. You can specify what percentage of the radius is hollow.
  • Twist (begin/end): Puts twists into the object, warping its shape as well as texture alignment.
  • Taper: Reduces the size of the top or bottom sides (x or y axes, negative or positive) of the prim.
  • Top Shear: Shifts (shears/skews) the top surface of the object away from the bottom. You can shift the X and Y axes separately.
  • Dimple (begin/end): Cuts a hole in a sphere from ring of latitude (you specify the percentage) to the top or bottom of the Z axis. The dimple cuts straight to the origin of the object (leaving a cone-shaped hole).

Three useful features

You may find the following features useful as you build and move objects:

  • Show Hidden Selection – Choose Build Options Show Hidden Selection to see the hidden contours and planes of a selected object.
  • Show Light Radius for Selection – This feature shows the range of illumination for a lighted object. To use it:
    1. Right-click the desired object and select Edit Features.
    2. Select the checkbox next to Light. The object is now a light source.
    3. Choose Build Options Show Light Radius for Selection to see how far the emitted light from the object travels.
    4. To adjust the distance of the object’s emitted light, right-click it, select Edit Features, and click the up and down arrows to increase or decrease the Radius.
  • Show Selection Beam – The selection beam is the line of particles you see when you are pointing at and manipulating objects. The feature is on by default, but if you think it gets in the way, you can disable it: Choose Build Options and uncheck Show Selection Beam. 

Using Shift-drag to copy objects

You can Shift-drag to copy an object you have permission to copy. This isn’t obviously stated in the build tools but is a popular way to copy objects. Here’s a simple example:

  1. Right-click the ground and choose Build.
  2. Click the ground again to rez a generic cube.
  3. Right-click the cube and choose Edit. The positioning arrows appear.
  4. Hold down Shift, left-click one of the arrowheads, and drag the object. You’re dragging the original, and a copy is left behind at the original location.


The Undo Feature

The Social Mouse’s Undo is used to revert certain changes to an earlier state. While selecting an object, use Build > Undo, or the much quicker keyboard shortcut of Ctrl-Z.


Undo doesn’t work if you have:

  • Changed any of the texture settings on an object. (It won’t switch back to the previous setting.)
  • Deleted an object. (It won’t bring it back inworld.)
  • Added contents to an object. (If you drag a no-copy object from inventory into another object’s contents, selecting Undo won’t take it out.)

This isn’t all-inclusive; Undo generally doesn’t work for most of an object’s parameters.
