In this comprehensive tutorial, we'll master the creation of a television outlet symbol in AutoCAD. This fundamental electrical symbol appears frequently in residential and commercial drawings, making it essential for professional drafting workflows. Let's begin by establishing our drawing environment with File, New.
We'll leverage our established template to maintain consistency across our electrical symbol library. Navigate to File, Save and designate this drawing as "television-outlet." This naming convention ensures easy identification and retrieval in complex project folders.
After clicking Save, we'll establish our electrical symbols layer by adding "E-syms." This organizational approach separates electrical elements from other drawing components, streamlining layer management in comprehensive architectural drawings.
Configure the layer color to 61, which provides optimal visibility against standard drawing backgrounds. Make this your active layer and close the Layer Properties dialog to maintain a clean workspace.

The television outlet symbol follows industry-standard dimensions: a one-quarter inch by one-quarter inch rectangle. This sizing ensures compatibility with standard electrical templates and maintains proper scale relationships in both residential and commercial drawings.
Precise positioning is crucial for professional results. The rectangle sits precisely on top of a one-eighth inch vertical line, with the line's bottom anchored at coordinate 0,0. This standardized positioning ensures consistent symbol placement across different drawings and maintains compatibility with industry electrical symbol libraries.
Understanding this coordinate relationship is fundamental—the bottom of the positioning line serves as our reference point for all subsequent measurements and placements.
We'll begin construction with the positioning line. Access the Line command from your drawing toolbar or command line.
Establish the first point at coordinates 0,0. For the second point, we'll use absolute coordinates for maximum precision: 0,1/8. This creates a perfectly vertical one-eighth inch line. Press ENTER to confirm the line placement.
Press ENTER again to exit the Line command, then execute Zoom Extents to optimize your view of the newly created element.
Quality control is essential in professional drafting. Verify the line's accuracy using AutoCAD's Quick Measure tool, which provides instant dimensional feedback without creating permanent dimension objects.
When you hover adjacent to the line, the length measurement appears automatically—confirming our one-eighth inch specification.
Press Escape to exit the measurement mode. Now we'll construct the primary rectangle component of our television outlet symbol.
For optimal efficiency, we'll draw the rectangle at a convenient screen location, then use AutoCAD's Move command with point-to-point positioning to achieve precise placement. This approach often proves faster than attempting to calculate exact coordinates during initial creation.
Position your cursor in an open area and initiate the Rectangle command. We'll demonstrate AutoCAD's powerful Dimensions option for this construction.
The Dimensions option appears as 'D' in the command line. Type D and press ENTER to access this precise sizing method.
AutoCAD now prompts for length, width, and quadrant specifications—providing complete dimensional control over rectangle creation.
Enter 1/4 for the length and press ENTER. Input 1/4 for the width and press ENTER again.
The final prompt requests the quadrant specification relative to your initial point. This determines the rectangle's orientation and positioning relative to your starting corner.
Click in the desired quadrant to complete the rectangle. AutoCAD generates a perfect one-quarter inch by one-quarter inch rectangle meeting our symbol specifications.
Precise positioning requires moving the rectangle from its current location to the correct position atop our reference line. This involves a point-to-point move from the rectangle's midpoint to the line's endpoint.
This exemplifies AutoCAD's point-to-point methodology: define the source point and destination point for exact object placement without manual coordinate calculations.
Verify that your Object Snap settings remain active for Endpoint and Midpoint detection. These snaps ensure precise connection points and eliminate positioning errors.
Execute the Move command, select the rectangle, and press ENTER to confirm selection. Move from the rectangle's midpoint to the line's endpoint, creating perfect alignment. Press Control+S to preserve your progress.
Professional electrical symbols require clear identification text. We'll add "TV" text at one-eighth inch height, perfectly centered within the rectangle boundaries.
While single-line text could accomplish this task, Multi-line Text offers superior flexibility and formatting control. This becomes particularly valuable in complex drawings where text modifications may be required.
The distinction is important: single-line text creates individual objects for each line, while multi-line text maintains multiple lines within a single object. This flexibility proves invaluable for title blocks, schedules, and detailed annotations common in professional electrical drawings.
Access Multi-line Text from your text dropdown menu. This command provides comprehensive text formatting capabilities within AutoCAD's drawing environment.
Multi-line Text requires boundary definition before text entry—unlike word processing applications that allow unlimited text flow. AutoCAD's infinite drawing space necessitates explicit text boundaries for proper placement and formatting.
Since AutoCAD operates in a boundless drawing environment, we must define where text appears within specific boundaries. This approach ensures predictable text behavior and maintains drawing organization.
Use the rectangle itself as our text boundary box—ensuring perfect text containment within the symbol boundaries.
Click the rectangle's top-left corner, then its bottom-right corner to establish the text boundary. This creates a text area exactly matching our symbol dimensions.
The text editor opens with default settings, typically showing six-inch height—far too large for our electrical symbol application.
Modify the height to one-eighth inch to match our symbol scale requirements. Press ENTER to apply this change.
Current justification shows as Top Left—the standard default inherited from common word processing applications.
This default works well for documents but proves inappropriate for technical symbols requiring centered text presentation.
Change the justification to Middle Center, ensuring the "TV" text appears perfectly centered both horizontally and vertically within our rectangle boundaries.
Type "TV" and click the Close Text Editor button to complete the symbol construction. This creates professional-quality text that maintains consistent appearance across different drawing scales.
Execute Zoom Extents for optimal viewing, then press Control+S to save your completed television outlet symbol. This symbol now joins your professional electrical symbol library.
In our next tutorial, we'll expand our electrical symbol repertoire with additional essential symbols, building a comprehensive library for professional electrical drafting applications.
