Here are some simple exercises to help you understand how to use 1-point, 2-point and 3-point perspective grids to sketch structures. That's what they're there for, but at the same time, you need to get used to drawing in line with this 2D/3D system, and train your hand and eye to work through the visual tricks of the paper wormhole. The view is so realistic, they draw your eye straight to the focus point aka vanishing point at the "far end" of the paper, and you're drawn right into the third dimension. Perspective grids create a 3-dimensional framework on a 2D surface.
Different grids can help you to sketch different views - for example, a square grid offers instant metric visualization, an isometric view shifts a workspace to a 30 degree angle, while a dot grid can provide loose frameworks for connecting the dots between ideas (pun slightly intended). The center of the bounding box surrounding the objects’ origins.A grid is a framework to help you conceptualize and structure your ideas. The Cursor to Selected option will snap the 3D cursor to
With the Bounding Box Center pivot point active,.The Cursor to Selected option is also affected by the current Pivot Point. Cursor to Active Places the cursor to the origin of the active (last selected) object. Cursor to Grid Places the cursor to the nearest grid point. Cursor to Center Places the cursor to the origin of the world (location 0, 0, 0). Cursor to Selected Places the cursor to the center of the current selection, unless see below. Selection to Active Moves the selection to the origin of the active object. Instead, they are centered around the 3D cursor, maintaining their relative distances. If there are multiple objects selected, they are not moved individually at the cursor position Selection to Cursor (Offset) Places the selection at the position of the 3D cursor. Selection to Cursor Moves each one of the currently selected object(s) to the cursor location.
Selection to Grid Snaps the currently selected object(s) to the nearest grid point. This menu provides a number of options to move the cursor or your selection to a defined point The Snap menu (also available from the 3D header in both Object Mode and Edit Mode Object ‣ Snap and Mesh ‣ Snap).
