How to Draw Title Blocks in AutoCAD using X-Reference

Drawing Title Blocks is one of the basic autocad requirements that needs to be mastered.

Assuming you already know how to use AutoCAD follow these guidelines, applicable to all autocad versions:-

  1. First, Create a Title Block Directory where you can put all your Typical Title Block Designs. Make sure your Title Block Drawings are named properly using Sizes as the prefix. Eg. A1-TBK-HOR.dwg. A1-TBK-CIVIL, etc.
  2. Draw your Title Blocks using 1:1 scale in Model Space, the way you want, put in only those standard letters like Scale, Drawn By, Dwg No, Company Names, Logos, etc, and leave out those non-standard lettering like project titles, client names, designer & checker  names, drafter names, empty. Make sure you use standard paper sizes, A1, A2, A3, A4. After you are done, move your Title Block such that the Lower LHS corner of the Title Block is at autocad coordinate 0,0. Set the Drawing Limits to exactly the Drawing Size. Save the file with a meaningful drawing name.
  3. To begin designing a Specific Title Block, just copy the Standard Title Block that you want from the Title Block Directory into your Project or Working Directory, and Rename the File to the project eg: A1-TBK-Project House. Edit everything to suit Project House, such as Titles, Client Name, Designer, Checker, Architects, Engineers, Drafters etc.. again leave the Non-Standard like Scale, Drawing Nos, Sheet Nos blank.
  4. On any Drawings where you need the Title Blocks, just use X-REF from the Project Directory, to insert the Title Block, to any scale in model space or 1:1 in Paper Space. This drawing will be inserted as a "block", do not explode this, if you do, you will not be able to update the title block in case design title block changes. If you decide to change the design of the title block, just edit on the Original Project Title Block and the rest of your drawings will be automatically edited & updated. You only need to add the non-standard texts. Avoid Creating Blocks or Inserting Title Blocks, use X-Ref instead.
  5. One cool method is you could use an Auto Lisp to automate the process where Standard & Non-Standard Title Blocks and Texts can be X-ref automatically, and editing non-standard texts becomes easier.
  6. This method of X-Ref can apply to many Standard Drawings which will automate detailing and reducing errors at the same time.

Sizes of Drawing Title Blocks

Sizes of Papers used commonly for Technical Drawings are based on ISO Standard, as follows :-

 Label  Sizes (mm)  Sizes (inch)
 A1  841 x 594 mm  33.1 x 23.4 in
 A2  594 x 420 mm  23.4 x 16.5 in
 A3  420 x 297 mm  16.5 x 11.7 in
 A4 297 x 210 mm 11.7 x 8.3 in

Title Blocks Lines should be drawn with an offset of at least 10 mm from the edge of the papers on all three sides except the left side, which should be set to at least 20 mm to allow space for binding on the left. More offsets may be required to suit individual Plotters, check their Manual for details.

It is convenient to also put Two Points at Top LHS and bottom RHS of the Title Block Boundary Line, which will be the "Window" Range to select if you plot to whatever scale in model space. However if you plot in paper space, plotting is always 1:1 but the Two Points will help you to center the title blocks.
