Decided to treat myself and bought Grid Modeler.Follow me on Twitter: Membership and Downloads: https://gumroad.co. Blender 2.92 Manual. The opacity of the grid can be controlled with the slider. When using the Canvas X-Ray option objects are drawn behind the canvas grid. Decrease the opacity of all the layers in the object other than the active one. The opacity factor can be controlled with the slider. Looking for an easy to use Hard surface modelling addon that would save you some time?Look no further.-. Face ‣ Grid Fill Grid Fill uses a pair of connected edge loops or a single, closed edge loop to fill in a grid that follows the surrounding geometry. The best predictable result can be achieved if you select two opposite edge loops with an equal number of vertices.

Display settings for Edit Lines in Edit Mode and Sculpt Mode.

Edit Line Color

Sets the color of the Edit Lines.

Canvas¶

In 3D space sometimes is difficult to assess on which plane are you drawing.The Canvas is a display overlay helper that shows a grid at the current Drawing Plane.You can enable the Canvas visualization in the Viewport Overlays.

See Drawing Plane for more information.

Color

Color of the Canvas grid lines.

Scale X/Y

Defines the X and Y scale of the Canvas.

Grid
Offset X/Y

Sets the Canvas position offset from the object’s origin.

Subdivisions

Specifies the number of subdivisions to use for the grid.

There are two types of snap operations that you can use in Blender. The first type snaps yourselection or cursor to a given point while the second type is used during transformations(translate, rotate, scale) and snaps your selection to elements within the scene.

Snap Menu¶

Reference

Blender grid settings
Mode:Object, Edit, and Pose Mode
Menu:Object/Object type ‣ Snap
Hotkey:Shift-S

The Snap menu (also available from the 3D header in both Object Mode and Edit ModeObject ‣ Snap and Mesh ‣ Snap).This menu provides a number of options to move the cursor or your selection to a defined point(the cursor, selection or the grid).

Selection to Grid
Snaps the currently selected object(s) to the nearest grid point.
Selection to Cursor
Moves each one of the currently selected object(s) to the cursor location.
Selection to Cursor (Offset)
Places the selection at the position of the 3D cursor.If there are multiple objects selected, they are not moved individually at the cursor position;instead, they are centered around the 3D cursor, maintaining their relative distances.
Selection to Active
Moves the selection to the origin of the active object.
Cursor to Selected
Places the cursor to the center of the current selection, unless see below.
Cursor to Center
Places the cursor to the origin of the world (location 0, 0, 0).
Cursor to Grid
Places the cursor to the nearest grid point.
Cursor to Active
Places the cursor to the origin of the active (last selected) object.

The Cursor to Selected option is also affected by the current Pivot Point. For example:

  • With the Bounding Box Center pivot point active,the Cursor to Selected option will snap the 3D cursor tothe center of the bounding box surrounding the objects’ origins.
  • When the Median Point pivot point is selected,Cursor to Selected will snap the 3D cursor tothe median of the object origins.

Transform Snapping¶

Reference

Mode:Object, Edit, and Pose Mode
Header:Snap
Hotkey:Shift-Tab

The ability to snap Objects and Mesh element to various types of scene elements duringa transformation is available by toggling the magnet icon (which will turn red)in the 3D View’s header buttons.

Magnet icon in the 3D View header (red when enabled).

Snap Element¶

Reference

Mode:Object, Edit, and Pose Mode
Header:Snap Element
Hotkey:Shift-Ctrl-Tab
Volume
Snaps to regions within the volume of the first Object found below the mouse cursor.Unlike the other options, this one controls the depth(i.e. Z coordinates in current view space) of the transformed element.By toggling the button that appears to the right of the snap target menu (see below),target objects will be considered as a whole when determining the volume center.
Face
Snap to the surfaces of faces in mesh objects. Useful for retopologizing.
Edge
Snap to edges of mesh objects.
Vertex
Snap to vertices of mesh objects.
Increment

Snap to grid points. When in Orthographic view, the snapping increment changes depending on zoom level.

Note

In this context the grid does not mean the visual grid cue displayed.Snapping will use the resolution of the displayed grid,but all transformations are relative to the initial position (before the snap operation).

Snap Target¶

Snap target options become active when either Vertex, Edge,Face, or Volume is selected as the snap element.These determine what part of the selection snaps to the target objects.

Active
Moves the active element (vertex in Edit Mode, object in Object Mode) to the target.
Median
Moves the median of the selection to the target.
Center
Moves the current transformation center to the target. Can be used with 3D cursor to snap with an offset.
Closest
Moves the closest point of the selection to the target.

Active.

Additional Snap Options¶

In Edit Mode.

As seen by the yellow highlighted areas in the image above,additional controls are available to alter snap behavior. These options vary between mode(Object and Edit) as well as Snap Element. The four options available are:

IconDetails
Align rotation with the snapping target.
Project individual elements on the surface of other objects.
Snaps elements to its own mesh.
Consider Objects as whole when finding volume center.
Snap to grid, instead of snapping in increments relative to the current location.

Multiple Snap Targets¶

Once transforming a selection with Snapping on (not just when holding Ctrl),you can press A to mark the current snapping point, then proceed to mark as many othersnapping points as you wish and the selection will be snapped to the average location of allthe marked points.

Marking a point more than once will give it more weight in the averaged location.
