The tutorials in this section show how to add Dimensions and Arrows (or leader lines) to your drawing.
As mentioned in the previous section covering Text objects, annotation objects generally are not part of your model, but rather provide information about your model. Annotation objects are created in "Paper space" as opposed to "Model space." When specifying size values for annotation object attributes (text height, arrow size, etc.) these values are measured in "paper units" (unscaled) rather than "model units."
Annotation objects can be drawn by locating points with your cursor (mouse, stylus or your finger), entering coordinates (absolute, delta or polar), or by using the arrow keys on your keyboard. Each of these techniques is covered in Drawing lines and entering points. In the tutorials that follow you will be asked to enter points at specific coordinates. You can use whichever input technique you prefer to enter the points.
The tutorials in this section assume that you have created a full-scale metric ISO A4 size drawing and have your device in the "landscape" orientation. You can review the steps to create this drawing in the Create a full-size metric A4 drawing sheet task.
In this exercise we're simply setting the view to show an enlarged area in the center part of your drawing. All of the exercises in this section will use this view.
This tutorial shows how to add dimensions to an object, in this case, a simple rectangle. Dimensions are drawn by locating a series of points that define the anchor point (the point from which distances are measured), direction (the axis along which distances are measured), the dimension line offset (the location of the first dimension line), and the dimension nodes (the points to which each distance is measured).
We'll start by drawing the rectangle.
32for the width and
18for the height.
(100, 118). This will be the anchor point for the dimension.
(132, 118)(horizontally inline with the anchor point).
(116, 109). Notice that a rubber band dimension object follows the cursor. Enter a point at the center. A dimension showing the horizontal distance from the anchor point to the rectangle's center point has been added to your drawing.
(132, 118)and enter a point. A dimension showing the horizontal distance from the anchor point to the upper left corner has been added. Since the Baseline dimension type is selected, each distance is measured from the anchor point and the dimensions are stacked.
Esckeys on your keyboard.
(132, 100). Since the Incremental dimension type is selected, each distance is measured from the previous dimension node and each dimension is located inline with the previous dimension.
In the previous tutorial, all of the dimensions were measured horizontally or vertically. Dimensions can be measured at arbitrary angles using exactly the same techniques.
In this tutorial we will dimension each edge of a triangle. We will draw the triangle as a multi-segment line.
(200, 140), and
(186, 140), and
Arrow objects are similar to multi-segment lines, except that they can include symbols at one or both ends of the line. These symbols can be various kinds of arrows, circles or ellipses. The symbols can be open or filled. Arrow objects can be used for a variety of purposes, including leader lines, dimension components, or other call-outs.
In this tutorial we draw arrow objects that represent radius and diameter dimensions for a circle. We'll start by drawing the circle.
10for the radius.
(180, 70). A 10 mm radius blue circle will be drawn at this location.
(194, 86). Notice that a rubber band arrow follows the cursor.
(200, 86). An Object snap point will appear at the vertex. Enter a point.

In this tutorial we explore various ways that attributes of existing dimensions can be changed.
Open the finished tutorial drawing The steps in this tutorial assume that you have completed the previous tutorials in this section (Tasks 7.1 through 7.4) and your current drawing contains the objects created in these tutorials. If you haven't completed the tutorials or if you want a fresh start, you can open the completed drawing by tapping the green button.
The first set of attributes we'll change are located in the General settings panel. Changing these values will affect all objects in your drawing.
All of the dimension and arrow objects created in these tutorials have been drawn on "Layer 001" using the "Small" text style and the "Small filled" arrow style. We can change the appearance of all of these objects by changing the Layer definitions, Text style definitions and Arrow style definitions in Settings.
Each of the changes we made in the previous steps affected all of the dimension objects in the drawing. We can change the attributes of individual dimension objects using the Properties tool.
