1 AccuDraw Inga Morozoff, Bentley Systems, Inc. Introduction Developed by Rob Brown and introduced in PowerDraft in It does not create or manipulate elements or objects instead, it assists in their creation and manipulation. Mimics using a drafting machine Bentley Systems, Incorporated 1

2 Basics Found on the Primary Tools toolbar Dockable dialog with two modes: Rectangular and Polar. Toggle between the modes by tapping the space bar Bentley Systems, Incorporated The Compass The compass is located at the last datapoint. Composed of three parts: The origin is the center of the compass and is always location 0,0 regardless of where the compass is in the design. The dashed rectangle or circle is referred to as the drawing plane indicator. The axis ticks are AccuDraw s axis markers and are independent of both the drawing axis and the view axis Bentley Systems, Incorporated 2

3 Workflow When enabled, AccuDraw considers three things and changes it s behaviour accordingly. First, it considers the current tool and switches between rectangular or polar mode as needed Bentley Systems, Incorporated Second, it considers the location of the pointer with respect to the origin of the compass. The values in the key-in fields to reflect the distance the pointer is from its origin. If no data point is entered, the values show absolute coordinates Bentley Systems, Incorporated 3

4 Finally, AccuDraw considers and interprets keyboard shortcuts. These are single or dual character key-ins to drive its behavior. An example is using the space bar to toggle between the Rectangular and Polar modes. Review all the shortcuts by pressing? Bentley Systems, Incorporated Operational Rules Enter a datapoint to fix the initial position of the compass. This becomes location 0,0 and all measurements will be taken from there. (Think about manual drafting.) Move your pointer in the direction you wish to draw. This sets the focus and populates the distance fields. Without moving the pointer, enter values in the key-in fields. No need to click, swipe out, adjust the focus just key-in the numbers Bentley Systems, Incorporated 4

5 AccuDraw dialog focus To put the focus in AccuDraw: Click the AccuDraw window If the focus is Home, press Space Bar If the focus is Home, press F11 If the focus is not Home, press ESC, then Space Bar. Key-in AccuDraw Dialog Enter a datapoint on the screen Tip: Enable Workspace > Preferences > Look and Feel > Auto focus Tool Settings The key-in shortcuts are only available when the focus is in AccuDraw Bentley Systems, Incorporated The key-in fields input focus As you move the pointer around the screen, AccuDraw continually updates the fields in the AccuDraw window. The field that gets the focus is determined by the direction and distance the pointer is from the origin. The focus field with the largest value, gets the input focus. This is determined by how far the pointer is from the origin. If needed, change the focus by pressing TAB or Arrow-Up or Arrow-Down Positive or negative values is determined by the quadrant the cursor is in Bentley Systems, Incorporated 5

6 Quadrants -,+ +,+ +,- -, Bentley Systems, Incorporated Indexing AccuDraw can index to: Each axis The Origin The previous distance Operates similar to AccuSnap get close and temporarily lock on. Can replace the Axis Lock in all but a few situations. To override axis indexing, press LI shortcut Bentley Systems, Incorporated 6

7 Locking Values A field is automatically locked when entering a value from the keyboard. A temporary construction line appears to indicate the keyed in distance from the origin (0,0) This equates to scribing a construction line with your set square when using a drafting machine or T-square Bentley Systems, Incorporated Keyboard Shortcuts AccuDraw s behavior is influenced by the current tool, the location of the pointer and keyboard shortcuts. Keyboard shortcuts are singe and double character commands AccuDraw window must have the focus in order to issue a key-in. Review all the shortcuts by pressing? Bentley Systems, Incorporated 7

8 Must-Know shortcuts Space Bar Toggles between rectangular (X,Y) and polar (Distance and Angle) mode. X, Y, D, A Toggles the locks for the X, Y, Distance and Angle fields Bentley Systems, Incorporated Enter (Smart Lock) Causes AccuDraw to index to the closest axis and lock the opposite field value. Smart Lock allows you to draw in one direction, while snapping in another. Q (Quit) Quits AccuDraw Bentley Systems, Incorporated 8

9 V (View Rotation) AccuDraw automatically rotates to the angle between the last two datapoints. To return the compass to be parallel to the view axis, press V. O (Set Origin) Moves the compass to the current pointer location or tentative point. Can also be done by doing a CTRL+Tentative Bentley Systems, Incorporated RQ (Rotate Quick) Temporarily changes the rotation of the compass to a user defined angle. Once a data point has been entered, the compass resumes its normal orientation. K (Keypoint Snap Divisor) Opens the Keypoint Snap Divisor dialog box. I (Intersect Snap) Activates the Intersect Snap mode override. C (Center Snap) Activates the Center Snap mode override Bentley Systems, Incorporated 9

10 ~ (Bump Toolsettings) The tilde character is used to bump the value of the first adjustable setting in the tool settings window to the next valid value. For example, when using the Place SmartLine tool, tilde will change the Segment Type from Line to Arcs. To bump the second tool setting use the key in: accudraw bump toolsetting 2 To bump the third tool setting use the key in: accudraw bump toolsetting 3 HA (AccuDraw on Hold) Suspends AccuDraw until HA is reissued. HS (AccuSnap toggle) Turns AccuSnap on or off. HU (AccuSnap Suspend) Suspends AccuSnap until a Reset is issued Bentley Systems, Incorporated Custom Key-ins Key-ins can be customized. Stored in shortcut.txt defined by MS_ACCUDRAWKEYS Can be used to create aliases for common operations. For example, PL for activating Place Line. PF for activating Place Fence etc Bentley Systems, Incorporated 10

11 Settings To access AccuDraw Settings dialog: Press the keyboard shortcut GS Select Settings > AccuDraw Right click the AccuDraw icon and choose Properties Key-in AccuDraw Dialog Settings Operations tab contains settings to change the operation of AccuDraw Bentley Systems, Incorporated Display tab settings that change display features. Additional display settings available by key-in: AccuDraw Settings Size xx sets size of compass, default size is 40. AccuDraw Settings Northeast changes the to Northing and Easting. AccuDraw Settings XY changes the display to X and Y Bentley Systems, Incorporated 11

12 Coordinates tab defines the Coordinate System, Unit Roundoff, and Indexing settings. Tip When working with very fine distances, it s often helpful to reduce the Tolerance setting. This adjusts how close your pointer needs to be to the axis until it indexes. The value is expressed in screen pixels Bentley Systems, Incorporated Tips When angle format is in bearing mode, replace the degree symbol (^ ) with a semi-colon ( ; ), apostrophe ( ), or two periods (..) When specifying quandrants, use the following numbers: NE = 1, NW = 2, SW = 3, SE = 4 For example, N35^30 45"E can now be 1 35;30 45 To place a north arrow on a rotated view, use this keyin: ac=north;aa=0;accudraw dialog;accudraw setorigin;accudraw rotate top;%d;accudraw rotate view;accudraw quit;reset Bentley Systems, Incorporated 12

13 Pop-up Calculator The pop-up calculator allows you to perform mathematical operations on the fly. Activated by pressing +, -, *, /, = in any text field that supports it. This includes AccuDraw's key-in fields and many other fields, such as Active Angle or Active Scale. Can perform advanced mathematical functions: trigonometric and logarithmic functions, multiple operators, parentheses, and C expressions. Activate by pressing = Bentley Systems, Incorporated cos(angle) trigonometric cosine of angle tanh(value) hyperbolic tangent of value sin(angle) sine of angle exp(value) exponential of x asin(value) arc sine of value log(value) natural logarithm of value atan(value) arc tangent of value log10(value) base 10 logarithm of value atan2(valuey,valuex) arc tangent of valuey/valuex pow(x,y) x to y power tan(angle) tangent of angle sqrt(value) square root of value cosh(value) hyperbolic cosine of value fabs(value) absolute value of sinh(value) hyperbolic sine of value Bentley Systems, Incorporated 13

Can be used without the ACS. Compass changes to show inner circle or square Bentley Systems, Incorporated What is an ACS An auxiliary coordinate system (ACS) is a coordinate system with an orientation, and/or an origin, different from those of the DGN file coordinates (the Global system). Although not exclusively a 3D concept, an ACS is most useful in 3D modeling as a drawing aid. By using an ACS that corresponds to the location and orientation of a particular element, you can enter data points relative to parts of the model rather than the global origin. Although using ACSs may seem complicated, AccuDraw uses them as a basic part of its 3D functionality Bentley Systems, Incorporated 14

15 ACS Plane Lock and ACS Plane Snap Lock The ACS Plane lock forces data points to lie on the ACS plane. The ACS Plane Snap lock forces snapped datapoints to lie on the ACS regardless of what was snapped to Bentley Systems, Incorporated Shortcuts related to the ACS LP - Lock ACS Plane and ACS Plane Snap Toggles ACS Plane and ACS Plane Snap locks LA - Lock ACS Plane toggles the ACS Plane lock LS - Lock ACS Plane Snap toggles the ACS Plane Snap lock RA Rotate ACS - Used to create an ACS by rotating the compass.
