Technical illustration is a specialized field in the world of graphics and design. IsoMaker-Pro, allows you to harness the power of AutoCAD for the creation of complex isometric drawings.

IsoMaker-Pro is fully integrated with AutoCAD (WIN95,WIN98,WIN2000,ME,XP,Vista).This program comes with a windows setup and uninstall programs.

Illustrating the Challenges:
Whether in the aerospace or transportation industry, manufacturing electrical components or metal parts, your firm’s need to visually communicate product information has never been more crucial.

Today, precise technical illustrations are a vital element of the product assembly, operation and service, sales, and support materials your company relies on to compete successfully.

The challenge? To convey complex part views with precision and quality while reducing costs, increasing productivity and accelerating the technical illustration process.

The solution? IsoMaker-Pro.



Isometric Fillet:

Filleting connects two objects with a smoothly fitted arc of a specified radius. Although an inside corner is called a fillet and an outside corner is called a round, AutoCAD treats both as fillets.

If both objects being filleted are on the same layer, the fillet line goes on that layer. If the objects are on different layers, the fillet line goes on the layer of the first line picked. You can onlyfillet line segments on the isometric angles.

The fillet radius is the radius of the arc that connects filleted objects. By default, the fillet radius is the last radius set. Changing the radius affects subsequent fillets but not existing ones.

System variables FILLETRAD stores the current fillet radius.

Offsetting Objects:

Offsetting creates a new object that is the same as the selected object, at a specified distance and on a isometric angle from the selected object. You can offset lines, arcs, circles, 2D polylines, ellipses and elliptical arcs.

Isometric Ellipses:

Full ellipses can be created to represent circles in isometric drawings.

Isometric Elliptical Arcs:

Isometric elliptical arcs are drawn using the first axis endpoints and the second axis distance, for full ellipses. You then specify start and end angles. The apex of the angle is the center of the ellipse, and the major axis is defined as 0 degrees. The start angle defines the start point of the elliptical arc. The end angle defines the endpoint, and the arc is drawn between these points in the direction set by the ANGDIR system variable. If ANGDIR is 0, the angles are measured in a counterclockwise direction. If ANGDIR is 1, they are measured in a clockwise direction.

If the start and end angles are the same, you create a full ellipse. You can also specify a start angle and an included angle. The included angle is measured relative to the start point instead of from 0 degrees.

Isometric Plane:

Isometric Plane mode helps you create 2D drawings that represent 3D objects, such as cubes. Isometric drawings are not true 3D drawings. They simulate a 3D object from a particular viewpoint by aligning along three major axes. If the snap angle is 0, the axes of the isometric planes are 30 degrees, 90 degrees, and 150 degrees.

  •  Left Isometric Plane: Orients the snap and grid alignment along 90 and 150 degree axes.
  •  Right Isometric Plane: Orients the snap and grid alignment along 90 and 30 degree axes.
  •  Top Isometric Plane: Orients the snap and grid alignment along 30 and 150 degree axes.

Displays text on screen as it is entered:

ISOTEXT can be used to enter several lines of text on the isometric plane you have selected.   The text you are typing at the Enter Text prompt is displayed on the screen. Each line of text is a separate object. To end a line and begin another, press ENTER after entering characters at the Enter Text prompt. To end TEXT, press ENTER without entering any characters at the Enter Text prompt.

Isometric Dimension:

Design is often divided into four phases: drawing, annotating, viewing, and plotting. During annotation, the designer adds text, numbers, and other symbols to communicate such information as the size and materials of design elements or notes for constructing the design. Dimensions are a common drawing annotation.

IsoMaker-Pro provides dimension tools that you can use to measure isometric vertical and horizontal distances. When you start a dimension you are prompted for the following:

  • Specifies the first extension line:  You are prompted to specify the second one.
  • Specify second extension line:  Specify a point (2)
  • Specify location for dimension:  Specify a point


From IsoMaker-Pro main menu bar, click IsoMaker. The IsoMaker dialog box will appear. There are four sections to this dialog box:


From IsoMaker-Pro on the menu bar, click Fastener. The Isometric Fastener Library Dialog box will appear. The Fastener library allows you to create 2D  entities or 2D isometric entities of assorted Nuts, Bolts, Screws and Washers.  Select a standard fastener, thread style, other desired property, and click  the OK button.

To insert the Part, follow these steps:

  1. Click on the type of fastener desired.
  2. Click on the fastener type.
  3. Click on the fastener size.
  4. Click on the fastener length.


From IsoMaker-Pro on the menu bar, click IsoMaker-Pro. A drop down menu will appear. Click on Steel Shapes. The Steel Shapes Library Dialog box will appear. The Steel Shapes library allows you to create 2D entities or 2D isometric entities of assorted Structural Steel Shapes.

You may use the toolbar to achieve the same results.


  1. Click on the type of shape desired. (Solid or 2D) If 2D is selected, a drop down list will appear for the view plane.
  2. Click on the shape size in the Shape Size box.
  3. Click on OK at the bottom of the Dialog box to insert the shape.
  4. Click on the desired screen location to insert the shape.
  5. At the command line, you will be prompted for the length of the shape. Specify the length by selecting the second point, or by specifying a number distance in the AutoCAD current distance units format.
