The next dimension type that we’ll examine is adding a radius dimension, which is applied to arcs and fillets in a sketch. Angle dimensions always appear when lines aren’t constrained to be horizontal, vertical, or parallel. If you ever select two lines in xDesign thinking they’re parallel, and an angle dimension appears, this is an indicator that the lines aren’t actually parallel. In this case, we’ll use an angle of 15 degrees. All you do is click on both lines, and then click to place the angle dimension. In this case, we want to set the angle of the slanted line on the right relative to the vertical edge on the left. Creating an angle dimension can be as simple as selecting two lines that aren’t parallel to one another. The next type of dimensioning is creating an angle dimension. This distance, however, was just a way to show you the options when dimensioning between two points, so we’ll click “Undo” to remove it. In this case, we’ll set the direct distance between the two points. We can set the horizontal distance between them, the vertical distance between them, or the direct distance between the two points. We’ll click the first point and the second point, and then we can set the dimension in a few different ways. For example, let’s say we want to set a dimension between the upper left corner and the center point of the arc. This scenario can come up whenever a dimension needs to be set between two points that aren’t connected by horizontal or vertical lines. The last way to create a linear distance dimension is to select two points. To do this, we’ll click the line on the left and the point at the bottom of the angled line, and set the distance to be 70 millimeters. For example, we want to set the distance between this left edge and the point at the bottom of the angled line, which will determine the diameter at the base of the angled face of the “Revolve” feature. We’ll click the left edge, and then the other vertical line, and set the distance to be 105 millimeters.Īnother way is to set a linear dimension is to select a line and a point. We’ll also set the distance between the edge on the left and the vertical line just above the arc. For example, if we want to set the distance between the bottom edge and the horizontal line just above the arc, we can select the bottom edge and then click on the line right after, which allows us to set the distance between them, in this case we well set the distance as 60 millimeters. And we’ll set the other edge to be 25 millimeters tall.Īnother way to set a linear dimension is to select two lines that are parallel to one another. We’ll do this again for the bottom line, which we’ll set to 180 millimeters. Now the entire height of this line is defined in space. You then type in the dimension value, which we’ll set as 150 millimeters. The most common way is to simply click on a single line and click to place that dimension in free space. There are a few ways that a linear distance dimension can be created. The first type of dimension that we want to add is the linear distance dimension. With the button active, the cursor updates to show the dimension icon, and we can begin selecting sketch entities. To enable the “Dimension” command, simply click on the button in the action bar. Let’s examine how each of these can be added to this sketch to fully define the sketch. Dimensions allow you to specify the exact size of the sketch elements by adding dimensions for linear distances, angles between lines, sizes of radii, and diameters of circles. As we’ve seen, one way to define the size and relationships between sketch objects is through constraints, which allows them to be adjusted in specific ways, depending on how the geometry is updated.Īdding dimensions is the other method for defining the size and relationships between sketch objects.
