The location of the base point that is selected when creating a block is important.

Each block is unique and has a best location for its base point. When selecting the location for a base point, imagine what location would be best when the block is inserted into a drawing. Study the blocks below and the base point locations that were selected for each of them.

To insert a block with different X and Y scales, disable the Uniform scale box and enter the scales and as shown in the figures below.

The Key Principles in Module 33

1 A block is a collection of objects that acts as one object. Regardless of the number of times the block has been inserted into the drawing, it will not significantly change the size of the drawing's database.

2 The only way to remove a block from the block definition table is to purge it with the PURGE command.

3 Layer 0 (zero), assigned the color black/white, is a special layer and color for blocks. A block that was created using objects drawn on layer 0 will reside on and take the properties of the layer it is inserted on.

Step 1 Open the drawing AutoCAD 2D Lab 29-3.

(Figure Step 1)

Step 2 Using the SAVEAS command, save and name the drawing AutoCAD 2D Lab 33-1.

Step 3 Make the changes to the floor plan as shown in the figure. Note the size changes and some walls were removed. Use the STRETCH command to make all of the size changes. (Figure Step 3)

Step 4 Draw the 10 objects shown in the figures anywhere in model space. Draw them on layer 0. Ensure it is assigned the color Black/White. (Figure Step 4A and 4B)

Author's Comments: The plant block can be drawn by eye. Draw a construction circle and draw random lines. Use a 3 point arcs to complete it.

(Figure Hint 1)

Step 5 Create a block from each object. Use the following:

A Name the block as shown under the drawing.

B Set the BLOCK command to delete the blocks after creation.

C Set the base point as shown on the drawing.

D Give the block a description and set the Block unit to Inches.

Step 6 On layer Furniture, insert the blocks as shown in the figure. Match the drawing the best that you can by eye. (Figure Step 6)

Author's Comments: Insert one block and use the ARRAY or COPY commands to speed the process.

Step 7 Enable Module Layout D. On layer Viewport, create a viewport setting its scale to 1/2"=1'-0" and lock the display. In Paper space, on layer Text, label the rooms as shown. Pick your own text size and font. (Figure Step 7)

Step 8 Fill in the titleblock and turn layer Viewport off to complete the drawing.

Step 1 Open the Drafting Setting dialogue box. Set the grid and snap spacing to 0.05 units and any other settings to match the figure. Ensure that you disable the Adaptive grid and the Display grid beyond Limits box.

Step 2 With the grid and snap enabled, draw the five symbols shown below anywhere in model space. Draw them on layer 0. You will have zoom in close to draw the symbols. (Figure Step 2)

Author's Comments: Ensure that you draw each symbol by snapping to grid points as shown below. Notice how each of the connecting points of the symbols are located on a grid point.

Step 3 Make a block of each symbol. Name them with the name shown below the drawing. Set the Block units to Inches. Delete the objects when you the block is created.

Author's Comments: To draw the solid areas of the symbols, first draw the outside shape with polylines or circles and then hatch them with a solid pattern.

Step 4 Set the grid to 0.1 and the snap to 0.05. (Figure Step 4)

Step 5 On layer Object, draw the lines and the terminating circles for the schematic diagram.

Draw it by eye but do your best to match the figure. Ensure that you snap to grid point for the endpoints of all lines. (Figure Step 5)

Step 6 On layer Symbols, insert the blocks and trim the lines. (Figure Step 6)

Step 7 On layer Viewport, create viewport setting the scale to 1.25:1 and lock the display. (Figure Step 7)
