See how to use and place the POINT element type.
- [Instructor] In this exercise, we will learn to work with point commands to place cells and to create reference points in a drawing file. Open the file for chapter one more draw commands.dgn and using view groups, select the points model. In this first example, we will look at using the place active point command to create snappable and graphic points in the drawing file. First, let's open the place points toolbox. Using the task navigation dialogue, hold down the place active point command and select open points as toolbox.
Here you can see a list of all the point commands available in MicroStation. The first command we're going to take a look at is the place active point command located here. This command allows me to place a point graphic element anywhere in the drawing file. Using the tool settings dialogue, I can place a point graphic as an element, a text character, or a cell. If I place this point as an element with the current attribute settings, it is very difficult to see. What I need to do is exaggerate the line weight attribute to make the points more visible.
I will change the active line weight attribute to five and place a second point. Now you can easily see the element points. Next, I want to place a point using a text character so I will key in the character X using the tool settings dialogue which will automatically change the point type to character. Now when I place a point, instead of getting an element, I will get a text element using the X character. I can also place a point using a cell. For this example, I will use a parking light cell for the graphics to define the point element.
I will use the magnifying glass to open up the cell library dialogue and select the parking light cell. To assign this cell as a point cell, I need to pick the point button located at the bottom of the dialogue and close the dialogue. Now I can place an active point using this graphic cell. You might notice that there is no cell preview using this command, but once you issue the data point, the cell will appear. This cell point element is very useful when using point placement commands that allow you to control the point location and number of points.
Let's take a look at some of those commands. First, let's take a look at the place points between two points command. This command allows me to define a number of points placed between two data points. Again, using the tool settings dialogue, I will change the points to three and identify two points that define the edge of the parking lot. This will place three parking lights along the edge of the parking lot. You will notice that the angle is automatically set to zero using this command. And unfortunately, the angle setting is not available in the tool settings dialogue.
Let's undo this using Control + Z and try again. To change the active angle, I need to use the shortcut key AA=-45 to align the streetlights to the 45 degree parking lot. Place your cursor in the middle of the view window and press the Enter key to open the key in browser on the fly. Key in AA=-45 and press Enter. Now I can snap to the edge of the parking lot and place the three stop lights aligned correctly.
The next command I want to take a look at is the point on element command. This command allows me to place a point element at the nearest point to another element. If I issue a data point anywhere near the existing element, the defined point element will be placed on the nearest point on that element once I issue a second data point to accept it. Here you can see that I can drag the point along the element and left click to accept anywhere along the element. The next command allows me to place a point element at the intersection of two existing elements.
I will select the place point at intersection command and identify two existing elements. You can see that preview for the point element and I just have to left click to accept. The next point command allows me to place points along an element. Here I will select the place active point along element command and define the number of points as five. If I select an element and left click to accept, the points are placed along the element as defined. The last point command is the place point at distance along element which allows me to place a point at a specific distance along an element.
I will set the tool setting distance to 50 feet and select the edge of the road. A light cell is placed 50 feet along the element from the point where I identified the element. Again, control the angle of the point elements using the shortcut key AA= to define the active angle before placing the points. The next exercise will cover how to create additional linear elements such as B-splines, line streams, and calculated line geometry.
