Snaps help you precisely control the dimensions and placement of objects when you create them or transform them. There is also a Spinner snap for controlling the entry of values.
You can use objects within an XRef scene as snap references.
The snap commands listed below and described in this section are found on the main toolbar (except for Ortho and Polar; see their topics for details). They’re also available from the Grids And Snaps submenu of the Tools menu.
The buttons on the Snaps Toggle flyout provide control over the range of 3D space where snaps are active. A wide variety of snap types is available from the Snaps dialog, which you can use to activate different snap types as you work.
Angle Snap Toggle determines the incremental rotation for a number of features, including the standard Rotate transform. As you rotate an object (or group of objects), the object moves around a given axis in the increment you set.
Percent Snap Toggle increments scaling of objects by the specified percentage.
Spinner Snap Toggle sets the single-click increment or the decrement value for all of the spinners in 3ds Max.
When drawing a Line spline or Wall object, Ortho Snapping Mode constrains line creation to the horizontal or vertical directions relative to the active grid. That is, with Ortho on, you can draw only lines that are parallel to lines of the active grid.
When drawing a Line spline or Wall object, Polar Snapping Mode constrains line creation to angle increments determined by the Angle Snap setting relative to the active grid. To change the Angle Snap setting, right-click the Angle Snap Toggle button on the main toolbar and in the Options panel General group, edit the Angle setting.
