Overview

AccuSnap and AccuDraw are very useful modeling aids in OpenBuildings Energy Simulator.

Method

AccuSnap provides tentative snap functionality, providing graphical assistance — a “smart” pointer — for snapping to elements.

When AccuSnap is active, you simply select a tool and move the pointer over the elements, letting AccuSnap find and display the nearest snap point for you.

When the correct snap point is displayed, you enter a datapoint (left-click) to accept.

If required you can adjust various AccuSnap settings to configure AccuSnap for your mode of operation.

Various Snap Modes and AccuSnap options are accessed by long pressing on the status bar’s Snaps box at the bottom of the screen:

AccuDraw is a drafting and modeling aid that evaluates such parameters as your current pointer location, the previously entered datapoint, the last coordinate directive, the current tool's needs, and any directive you have entered via shortcut key-ins or AccuDraw options.

AccuDraw then generates the appropriate precision coordinates and applies them to the active tool.

AccuDraw's most recognizable feature is its compass, visible only when AccuDraw is active and has control of OpenBuildings Energy Simulator’s coordinate input, the compass acts as both a status indicator and a focus for your input.

When AccuDraw has focus, its compass has a transparent blue background. When it does not have focus, the compass appears grey.

AccuDraw has two modes rectangular coordinate mode and polar coordinate mode.

AccuDraw has its own window which contains the data entry fields and axis lock buttons for the currently active coordinate system. The AccuDraw window is docked along the bottom edge of the application
window.
