Note: These settings will be saved to the computer not the drawing and will remain until you change them. You may have to shut down AutoCAD then restart for the changes to take effect.
Assigning Lineweights
Note: Before assigning Lineweights to Layers make sure your Lineweight settings (Units for Listing and Adjust Display Scale) are correct. Refer to the previous page.
Assigning Lineweights to Layers
1. Select the Layer Properties Manager using one of the following:
2. Highlight a Layer (Click on the name).
3. Click on the Lineweight for that layer.
4. Scroll and select a Lineweight from the list.
5. Select the OK button.
Note:
Lineweight selections will be saved within the current drawing and will not effect any other drawing. The images above show lineweight sizes for the inch-helper.dwt. Metric sizes will appear if you are using the metric-helper.dwt.
Each layer may be assigned a transparency percentage from 0 to 90 percent. 0 would not be transparent at all and 90 would be 90% transparent.
Assigning Transparency to Layers
1. Select the Layer Properties Manager using one of the following:
2. Highlight a Layer (Click on the name).
3. Click on Transparency for that layer.
4. Select a Transparency from the list.
5. Select the OK button.
Note: Transparency selections will be saved within the current drawing and will not effect any other drawing.
Plotting Transparent Objects
Plotting transparency is disabled by default. To plot transparent objects, check the Plot transparency option in either the Plot dialog box or the Page Setup dialog box.
This will be discussed in Lesson 26.
Using layers is an important part of managing and controlling your drawing. It is better to have too many layers than too few. You should draw like objects on the same layer. For example, place all doors on the layer “door” or centerlines on the layer “centerline”.
When you create a new layer you will assign a name, color, linetype, lineweight, transparency and whether or not it should plot.
1. Select the Layer command using one of the following:
2. Select the New Layer tool and a new layer will appear.
3. Type the new layer name and press <enter>.
4. Select any of the features and a dialog box will appear.
Features:
Refer to the previous pages for controlling and selecting Layer colors, lineweights and transparency.
Refer to the next page for loading and selecting Layer linetypes.
Loading and Selecting Layer Linetypes
In an effort to conserve data within a drawing file, AutoCAD automatically loads only one linetype called “continuous”. If you would like to use other linetypes, such as “dashed” or “fenceline”, you must Load them into the drawing as follows:
Instructions:
1. Start a New file using either the inch-helper.dwt or the metric-helper.dwt
2. Draw the Lines below using:
A. Line command
B. Ortho (F) on.
C. Turn Increment Snap (F9) on
3. Select the appropriate layer, then select the Line command, then draw a line.
4. Select the appropriate layer, then select the Line command, then draw a line.
5. Select the appropriate layer, then select the Line command, then draw a line.
Are you noticing a pattern here?
6. Save the drawing as: Ex-3A
Exercise 3B
Instructions:
1. Start a New file using either the inch-helper.dwt or the metric-helper.dwt
2. Change the Increment Snap to 0.20” [5.08 mm] and Grid spacing to 0.40” [10.16 mm]. If you have the Snap and Grids set correctly it will be easy.
3. Make sure Snap and Grid status bar buttons are on.
