- [Instructor] The Construct Array tool is used to copy an element many times to create a rectangular or a polar array or an array along a path element. The Array tool can be found in the Home ribbon in the manipulate group. In this lesson, you will learn rectangular arrays and polar arrays. Continuing and learning .DGN, open the array elements model. In this first exercise, we'll be using the Construct Array tool using the rectangular method to copy the trees, to both sides of the road in one action. Select the Construct Array tool and set the following tool settings. Method, rectangular, active angle, zero, rows six, columns two, row spacing minus 12, column spacing 38.4. Note the use of minus 12 in the row spacing this directs Array tool to build the array, down from the original element. Had we needed to place the road to the left of the original, we would have needed a minus sign as well, select the tree cell with a data point and accept the selection with another data point. In this next exercise, we'll create a polar array at the points around the circle of the (indistinct) elements. Instead of calculating the angle between the items yourself, you can just enter the number of copies in the entire array, 10 in this instance, and set the total angle of 360. MicroStation will automatically calculate the delta angle for you. Let's give it a try with constructor array active, set the following method, polar, copies, 10, ignore the delta angle. Total angle, 360 degrees. Rotate items, enabled. Now MicroStation sets the delta angle to 36 based on the total angle and the total number of copies, select the pointy object. Snap to the center of the circle to define the center point of the new array and press data point. It's a perfect match to the left side object. In this next example will be setting the actual delta angle to it a bit more complex. We'll need to accommodate a two degree overlap. Note, when you're setting the angle, you subtract one of the copies from the total as the first step already exists, With the constructor array still selected set the following method, polar, copies, 15. Remember we have to subtract by one to allow for the original step to be included delta angle, 13, which is 15 degrees minus the two degree overlap, rotate elements, enabled. Select the first step with a data point. Data point in the middle of the white cross, the 16 steps appear with a two degree overlap as expected. In this lesson you learned rectangular arrays and polar arrays.
