Text Styles, Title Blocks, and Drawing Templates

Why Templates and Title Blocks Matter

Every drawing that leaves a drafting department carries a title block — a standardized panel that identifies the part, the project, the revision level, and the rules that govern the drawing. In manufacturing and marine environments, a drawing without a proper title block is not a usable document; inspectors, machinists, and class surveyors rely on that information to verify they are working from the correct revision and to apply the right tolerances.

AutoCAD's Drawing Template (DWT) file locks in all of these standards so that every drafter on a team starts from the same border geometry, the same text styles, and the same layers — before a single line of geometry is drawn. Creating and maintaining good templates is one of the highest-value skills a junior drafter can demonstrate on day one of a new job.

ASME Y14.1 Sheet Sizes and Border Geometry

ASME Y14.1 defines the sheet sizes and border dimensions used in US engineering drawing practice. For this lesson you will work with a B-size sheet: 11 × 17 inches. The standard specifies minimum border margins from the sheet edge; consult your course-supplied ASME Y14.1 reference sheet for the exact margin values. Draw the border as a closed polyline or four individual lines on a dedicated BORDER layer. The title block occupies the lower-right corner of the sheet and extends to the right border line.

Always model paper-space geometry at 1:1 in layout space. The viewport inside the border is where you set the drawing scale; the border itself is never scaled.

Text Styles: Two Roles, Two Styles

AutoCAD stores font, width factor, and oblique angle settings in a Text Style (command: `STYLE`). Creating named styles — rather than changing fonts ad hoc — ensures consistency and makes global updates easy.

For this lesson you will create two styles:

• NOTES — assign a standard sans-serif TrueType font (such as Arial or the SHX equivalent simplex.shx). Use a fixed height of 0.125 in (or leave height at 0 if you want MTEXT to control it). Width factor 1.0, oblique angle 0°. This style is used for all general notes, material callouts, and tolerance notes.
• DWG-NUM — assign a filled or bold font (such as Arial Bold or romans.shx at width factor 1.2) for the drawing number field so it stands out on a printed sheet.

After creating both styles, set NOTES as the current style before placing any text on the sheet.

MTEXT General Notes Block

The general notes block is placed in the lower-left area of the sheet interior, inside the border. Use the `MTEXT` command (not `TEXT`) so that the notes are contained in a single, resizable frame. MTEXT supports paragraph formatting, numbered lists, and column layout — all of which are useful when notes grow over time. Set the MTEXT width to fit the available space and assign the NOTES text style.

Typical manufacturing general notes include: the applicable drawing standard, units of measure, unless-otherwise-specified (UOS) tolerances, surface finish requirements, and material/finish specifications.

Building the Title Block with Attributes

The title block is built from two layers of information:

1. Fixed text — items that never change, such as the company name, the column headers (TITLE, DWG NO, REV, SCALE, etc.), and the tolerance table border.

2. Editable attributes — values that change with each job. AutoCAD stores these as ATTDEF (Attribute Definition) objects attached to a BLOCK.

Required Fields for This Program

Your title block must contain attributed fields for: Company Name (can be fixed text), Drawing Title, Drawing Number, Revision, Scale, Material, and Tolerances (or a pointer to the notes block). Each attribute needs a tag, a prompt, and a default value.

Attribute Workflow

1. Draw all title block lines and add fixed text labels on the TITLEBLOCK layer.

2. Use `ATTDEF` to place each attribute inside its cell. Set mode to Verify for critical fields like Drawing Number.

3. Select all title block geometry plus all ATTDEFs with a crossing window.

4. Use `BLOCK` → choose a name (e.g., TB-BSIZE) → pick a base point at the lower-right corner of the title block → check Convert to block.

5. The block is now embedded in the layout. Test it immediately: double-click the block to open the Enhanced Attribute Editor and confirm every field is editable.

Saving the DWT Template

With the border, title block, layers, text styles, and notes block all in place, go to File → Save As and change the file type to AutoCAD Drawing Template (.dwt). Name the file using your shop's naming convention (e.g., MFGB-SIZE-REV0.dwt) and save it to your templates folder. AutoCAD will prompt you for a description — write something useful such as B-size 11×17, ASME Y14.1, Manufacturing/Marine, Rev 0*.

To verify the template works, open a new drawing, select your DWT when prompted, then fill in attributes with `ATTEDIT` or the Enhanced Attribute Editor. Finally, plot to PDF at 1:1 and confirm the border, title block fields, and notes block all appear correctly.

Safety and File-Handling Notes

Templates are shared production files. Before modifying any master DWT: back up the existing file, increment the revision label, and record the change in a revision log. Corrupting a shared template can cascade into defective drawings across an entire project — a real safety risk in marine structural or machinery drawings where dimensions are inspected for code compliance. Never overwrite a revision-controlled template without supervisor approval.
