Project - AutoCAD Commands: Blocks and Layers

For this project, you'll prepare an AutoCAD drawing representing a plat map of a new subdivision called Oleson Village. A plat map is a drawing that shows such actual and planned features as streets and building lots. Your plat map will also show the location of trees, both those that will be saved as well as those to be removed. Data for the drawing will come from survey information that will be given to you as part of your project instructions. Using different layers with assigned colors and linetypes will be an important part of this drafting project. Also part of your project is some practice in annotating a drawing with text.

You won't need to print or plot your drawing for grading. When you're finished with the project, you'll submit a CD or flash drive containing the electronic data file for grading.

PREPARING THE PLAT MAP FOR PLOTTING

While you don't need to print or plot your drawing for it to be graded, part of your project involves preparing the file for plotting.

Draw a title block using the parameters listed here. (The drawing will be small, so you may have to zoom in to work with it adequately.)

Activate the layer called Trim. Using the LINE command, draw a 24 x 36 landscape border for trimming. You can position this border anywhere on your drawing and insert it into the right spot later.

Draw a border inside the trim lines. Make the margin on the left (one of the 24-unit sides) 1 unit wide and the remaining margins 1⁄2 unit wide. (An easy way to accomplish this task is to use the OFFSET command to offset the margins, use the CHPROP command to change the new lines to the correct layer, and then use the FILLET command with the radius set to zero to trim the lines.)

The area for the title block is 2 1/2" high and extends across the entire width of the bottom border. Figure 7 shows the correct layout of the title block with features described below. Divide the title block with vertical lines into six sections. The sections, beginning at the left, are

1. The revision block (6" wide)

2. A section for signatures (4" wide)

3. A section for the company name and logo (9 1/2" wide)

4. A section for the engineer's stamp (6" wide)

5. A section for the title of the drawing (8" wide)

6. A section for the project number and sheet number (1" wide)

Block your drawing of the border and title block. (You don't need to save it to the disk, so it doesn't have to be a wblock.) Name the block Border, and pick the lower-left corner of the trim line as your insertion point.

Insert the border, place it on the plat map somewhere, and accept the default settings.

The border was drawn and inserted at a 1 = 1 scale. Experiment with scaling the border block up by multiples of 10 until the border adequately surrounds the plat map. This process is a way in which you can judge the scale of the drawing. (If you lose track of the scale of the Border block, simply pick it with the LIST command.

You'll then see the scale factor of the block on the text screen.) Civil drawings such as this one are generally scaled and plotted in multiples of 10 (1"= 10', 1"= 40', 1" = 200', and so on). Choose an appropriate plotting scale.

Move the Border block so it surrounds the plat map. In this project, it's important to not move any of the entities of the plat itself. The survey is already complete.

The locations of all the entities use real-world coordinates, based on the location of BM#8332. You can move the border block to accommodate the coordinates from the survey.

Set the ltscale to the same value as the plot scale you've chosen, if different from the setting you chose at the beginning of the project.

Use the Zoom Extents option so the entire drawing will fill up the graphics screen.

Create a bar scale to reflect the scale you've chosen. A bar scale can be useful on most drawings. When reducing or enlarging a drawing, the bar scale will still be accurate with respect to the drawing. Having a bar scale may thus be more functional than simply stating with text that the drawing scale is, for example, 1" = 30'.

Research different bar scales, and choose one in which some areas of the scale are filled in. Use either a polyline with a width or the TRACE command to show these solid areas. Use ROMAN-8 style for the bar scale's text.

Fill in the title block with the title OLESON VILLAGE. Use the ROMAN-14 style, and fit the text.
