Creating Sheet Models for Drawing Production

Creating a Sheet model for printing as a drawing, typically involves working with the following components:

  • Design model(s) — where the design geometry is created
  • Saved views — Used to set up views required for the drawing.
  • Border attachment — Contains the border graphics and title block for plotted output.
  • Drawing model — where the annotations, dimensions, callouts, and other embellishments are added to the saved view.
  • Sheet model — The electronic drawing sheet.

There is no hard and fast rule about how to create Sheet models, or how to display your drawing information from your design or drawing models. Commonly, either of two methods are used, one that scales the border to enclose the design, or the other that scales the design to fit the border.

With both methods, for 3D work in particular, it is a good idea to have separate design models and sheet models. This lets you keep the purely drawing information, such as text and dimensioning, separate from the design information. Doing this reduces the likelihood of conflicts where others, for example, wish to reference the same design model for use in a drawing of a different scale.

Creating Sheet models automates the creation of drawing sheets for the printing of your designs. This process is similar to how the manual draftsperson works. Where it differs, however, is that instead of redrawing the model's geometry for each view, like the manual system requires, you simply attach views of the design model as references.

In other words, you attach as references views of your design geometry for each plan, elevation, section, and so on. The power of this system is that any changes made to the design model then is reflected immediately in each affected view in the drawings. The electronic version of the manual drawing sheet consists of:

  • Sheet model— The electronic drawing sheet.
  • Attached models/views — References of the design geometry and drawing models.
Note: Another common usage of references is in the creation of design compositions , which are used by engineers and other technical professionals to communicate through the visual content of their designs. Whereas a drawing is composed in a sheet model, a design composition typically is contained in a design model.
Sheet boundaries can be sized, scaled, rotated, and/or moved with the Sheet Boundary key-in.

Note: In DWG workmode, both rotation methods are limited to 90 degree increments. If an invalid value is entered, the value is rounded to the nearest 90 degree increment.

Key-in Description
  • Key-in with no arguments — You can resize the sheet interactively.
  • Key-in with one argument — You can resize the sheet to a predefined size (defined in sheetsizes.def) by using the defined name (in quotes) in the key-in.
  • Key-in with two arguments — You can create a custom sheet size by entering the height and width (separated by a space) in the key-in. Current MasterUnits are used in this case.
  • Key-in with no arguments — You can rotate the sheet by three selected points.
  • Key-in with one argument — You can define an absolute rotation value to set to the sheet boundary. The argument must be formatted in the same way as the current designs file's active angle. (i.e., DD.DDDD).
