Object Point of Origin

Artboard has many subtle methods for fine-tuning your work. One of these niceties is the point of origin, or center point, around which objects and symbols rotate and snap. Adjusting an object’s point of origin is simple and direct. Here’s how…

Point of Origin

Point_of_Origin.png

The point of origin of shapes, symbols, grouped objects, and images is represented with a blue “target” originally rendered at the center of the object. To change the point of origin, simply hold ⌘Command and grab onto the blue target and move it to any location within the object’s bounding box.

Drag the point of origin near the center of the object to snap it back into its original position.

Object Rotation Pivot Point

Object_Rotation_Pivot_Point.png

The direct rotate knob is represented with a purple handle offset to the right of the object’s center. Simply grab the rotate knob and move to rotate the object. The rotation pivots around the object’s point of origin. To change the point of origin, simply hold the Command-key then grab it and move it to any location within the object’s bounding box. Object rotation will now pivot around the new point of origin.

Resetting the Bounding Box

After rotating an object, you can reset the bounding box to perpendicular and return the point of origin to the center of the object. Select the object and choose Graphic > Reset Bounding Box from the main menu. As expected, the object’s appearance does not change, just its bounding box.

Drawing Shapes

Drawing shapes is simple and direct. Object handles and control knobs are visible and editable when using the single, direct Select [s] tool. Ovals, rectangles, arcs, wedges, stars, regular polygons and round rectangles are directly adjustable with special object handles – we call these Smart Shapes. No more switching tools or digging through menus to find the rotate command. Keep your attention where it should be – on your drawing canvas.

To Draw Rectangles, Ovals, Circles and Squares:

To_Draw_Rectangles__Ovals__Circles_and_Squares.png

Do one of the following:

  • RECTANGLE – Choose the Rectangle [r] tool, press and drag the cursor to begin drawing the shape, release the cursor to end the shape.
  • SQUARE – Choose the Rectangle [r] tool, hold the SHIFT-key when drawing to maintain the aspect ratio, press and drag the cursor to begin drawing the shape, release the cursor to end the shape.
  • OVAL– Choose the Oval [o] tool, press and drag the cursor to begin drawing the shape, release the cursor to end the shape.
  • CIRCLE – Choose the Oval [o] tool, hold the SHIFT-key when drawing to maintain the aspect ratio, press and drag the cursor to begin drawing the shape, release the cursor to end the shape.

To Draw Open and Closed Paths:

To_Draw_Open_and_Closed_Paths.png

Do one of the following:

  • AN OPEN PATH – Choose the Irregular Polygon [p] or Bezier Path [b] tool, click onto the drawing canvas to add the first point; continue clicking to add additional points connected by path segments; double-click to end the path or press the ESC-key to end the path.
  • A CLOSED-LOOP PATH / IRREGULAR POLYGON – Choose the Irregular Polygon [p] or Bezier Path [b] tool, click onto the drawing canvas to add the first point; continue clicking to add additional points connected by path segments; click onto the first drawn point to automatically end drawing the path; the coincident points will act as a single point.
  • To OPEN A CLOSED LOOP PATH – Choose the Select [s] tool, hold the CMND-key and drag the last point drawn away from the first point.

To Formally Close (or Open) Paths that Loop:

By default, the first and last placed points on a loop are treated as a single point when they are coincident (or overlapping). However, the path is not formally closed (with a straight line segment between first and last points).

To change this behavior so paths are formally closed when you end a path by clicking on its first placed path:

  1. Open the (app) > Preferences… Editing in the main menu.
  2. Check (or uncheck) “Automatically close paths when drawing”.

To open formally closed paths, do one of the following:

  • With the path selected, right-click and choose ‘Open’ from the contextual menu.
  • With the path selected, choose Edit > Paths (+Option-key) > Open from the main menu.

To Draw Arcs, Wedges, Stars, Regular Polygons, and Round Rectangles:

To_Draw_Arcs__Wedges__Stars__Regular_Polygons__and_Round_.png

Do one of the following:

  • ARCS – Choose the Arc [a] tool, click to place the center, move the cursor outward and click to define the radius, then move the cursor to define the arc and click to end the shape. Handles on Arcs directly control the object’s rotation, radius, and arc angle.
  • WEDGES – Choose the Wedge [w] tool, press to place the center, drag the cursor outward to define the radius, and release the cursor to end the shape. Handles on Wedges directly control the object’s rotation, radius, and arc angle.
  • REGULAR POLYGON / STAR – Choose the Regular Polygon [g] tool, press to place the center, drag the cursor outward to define the radius, and release the cursor to end the shape. Handles on Regular Polygons/Stars directly control the object’s rotation, radius, radial ratio, tip, and valley settings. Use the Geometry pane to change the number of sides (from 3 to 16). Additionally, to instantly create perfect triangles, hexagons, octagons and more, uncheck the “Star” setting in the Geometry pane and adjust the number of sides for a regular polygon.
  • ROUND RECTANGLES – Choose the Round Rectangle tool, press and drag the cursor to begin drawing the shape, release the cursor to end the shape. Handles on Round Rectangles directly control the object’s rotation and corner radius.

HINT: When your convert any of these special objects to a regular shape or path, they loose their “Smart” status and become regular shapes without dynamic editing handles.

To Reposition, Resize and Draw Out From Center:

Do one of the following:

  • REPOSITION / MOVE – Choose the Select [s] tool, press and drag the object, release. Alternatively, use the Geometry panel to adjust the location x/y position
  • RESIZE – Choose the Select [s] tool, press and drag any of the object handles, release. Alternatively, use the Geometry panel to adjust size.
  • DRAW OUT FROM CENTER – Choose a shape tool (such as Oval [o] or Rectangle [r]), hold the Alt/Option-key while drawing shape, release.
  • DRAW OUT FROM CENTER AND CONSTRAIN ASPECT RATIO – Choose a shape tool (such as Oval [o] or Rectangle [r]), hold the Shift-Alt/Option-key while drawing shape, release.

To Rotate Objects:

To_Rotate_Objects.png

Choose the Select [s] tool and do one of the following:

  • ROTATE – Select the object, press and drag the shape’s purple rotation handle, release. Alternatively, use the Geometry panel to adjust angle.
  • CONSTRAIN ROTATION ANGLE TO 15-DEGREE INCREMENTS – Select the object, hold the SHIFT-key and drag the shape’s purple rotation handle, release.
  • REPOSITION OBJECT CENTER POINT – Select the object, press and drag the center blue crosshair target, release.
  • ROTATE SEVERAL OBJECTS AROUND A COMMON PONIT – Group the objects, reposition the center target for the group as desired, and rotate.

HINT: To quickly return a rotated object to no rotation, double-click its rotation knob.

Use the Geometry Panel to Precisely Adjust an Object’s Size and Position:

Use_the_Geometry_Panel_to_Precisely_Adjust_an_Object_s_Si.png

While objects may be resized and repositioned directly, the can also be precisely adjusted using numeric input in the Geometry panel. (located in the lower left sidebar).

Do one of the following:

  • EDIT NUMERIC INPUT – Highlight or double-click the existing number and type in a new number, then click back onto your drawing canvas to remove the focus from the Geometry panel.
  • LOCK (OR UNLOCK) ASPECT RATIO – When changing object width and height in the Geometry panel, click the lock icon open (or closed).

HINT: The numeric input menu is context sensitive to the current selected object and the object type is displayed. Additional special object settings, such as star tips and valleys will be revealed when available. To hide the Geometry panel, click the Geometry panel icon in the bottom of the window.

To Quickly Switch Between Shape and Edit Mode:

To_Quickly_Switch_Between_Shape_and_Edit_Mode.png

Drawing objects can be quickly converted between shape mode, in which the object has a bounding box, and edit mode, in which the shape is comprised of a path and its points.

Do one of the following:

  • Choose the Select [s] tool and double-click a shape or path object.
  • Choose Graphic > Convert To in the main menu.
  • Right-click the object and choose a convert-to option in the contextual menu.

Arcs, wedges, regular polygons/stars, and round rectangles are converted to regular shape objects in this process; double-click again to convert to path.

To Change the Size of Object Handles:

Choose (app) > Preferences… Options and change ‘Handles:’ to large or small.

To Show (or Hide) the Tooltip Feedback Window:

Choose (app) > Preferences… Editing and check (or uncheck) ‘Display dimensions when dragging objects’.

Object and Symbol Point of Origin

Ortelius has many subtle methods for fine-tuning your cartographic work. One of these niceties is the point of origin, or center point, around which objects and symbols rotate and snap. Adjusting an object’s point of origin is simple and direct. Here’s how…

Point of Origin

Point_of_Origin.png

The point of origin of shapes, symbols, grouped objects, and images is represented with a blue “target” originally rendered at the center of the object. To change the point of origin, simply hold the Command-key then grab onto the blue target and move it to any location within the object’s bounding box.

Object Rotation Pivot Point

Object_Rotation_Pivot_Point.png

The direct rotate knob is represented with a purple handle offset to the right of the object’s center. Simply grab the rotate knob and move to rotate the object. The rotation pivots around the object’s point of origin. To change the point of origin, simply hold the Command-key then grab it and move it to any location within the object’s bounding box. Object rotation will now pivot around the new point of origin.

Resetting the Bounding Box

After rotating and/or adjusting the point of origin of an object, you can reset the bounding box to perpendicular and return the point of origin to the center of the object. Select the object and choose Graphic > Reset Bounding Box from the main menu. As expected, the object’s appearance does not change, just its bounding box.

Point of Origin on Symbol Adornments

Point_of_Origin_on_Symbol_Adornments.png

When symbols are created, they retain the point of origin of the original object on which they are based.

Symbols are placed on tracks as a “adornments,” and are snapped to the track at their point of origin. Typically a symbol is centered on the path with its central point of origin. In some circumstances, it may be useful to have a point of origin that is off-center. For example, for floor plans, doors are placed to show the door opening outward from a wall. When placing a door symbol (available in the Ortelius default symbol set) on a wall drawn with a track tool, a door must be offset to one side of the wall. If you look closely at a door symbol while it is not snapped onto a track, you will see this is accomplished with an off-center point of origin.

Before the symbol is created, adjust the point of origin. The symbol retains this point of origin. When snapped to a track, the symbol adornment is offset based on its point of origin. The side of the line the offset symbol appears on is based on the drawing direction of the track. The adornment can later be rotated by right-clicking it and choosing the desired rotation setting from the context menu.
