Replace Tedious Data Entry with Intuitive Drawing

Tired of entering room and duct data with the input text forms? Why not switch to VISUAL data entry by using Drawing Board? Try it today and see why some consider it to be the easiest program ever made for drawing floor plans and ductwork.




You must have an active license for either Rhvac, Chvac or Ductsize. If you use a version of Drawing Board in Rhvac before version 2, you will need to upgrade to Drawing Board for Rhvac version 2 in order to use Drawing Board in Rhvac 10.


Drawing Board is a fast and simple program for drawing floor plans, ductwork, and any other items desired. Drawings can be quickly created by dragging and dropping drawing objects from the built-in object catalogs onto the drawing window. The drawing objects in Drawing Board are pre-programmed shapes such as entire room shapes, walls, doors, windows, and ductwork. To help make drawings more realistic, many other object catalogs are included to cover items like electrical, plumbing, furniture, and HVAC equipment. Many of the objects are intelligent in that they contain data useful for calculations in the Elite Software Chvac, Rhvac and Ductsize programs. A special feature of Drawing Board when used with Rhvac is that it can convert manual entry projects automatically into drawing based projects. See more about that here.

Drawing Board can be used for both residential and commercial projects. Drawing Board works as an integrated component within the Elite Software programs Rhvac, Chvac, and Ductsize.

A common use of Drawing Board is to create floor plans so that HVAC load calculations can be automatically performed from the floor plan. Ductwork can be drawn and manually sized if so desired or ducts can be automatically sized within Drawing Board by using the optional Graphic Manual D Ductsize software or the ASHRAE based Ductsize software. Additionally, Drawing Board for Rhvac can also use the optional Bill of Materials software to calculate material and labor costs.

Unlike other HVAC drawing systems, Drawing Board can do much more than just drawing floor plans and ductwork. Drawing Board provides general CAD (computer aided drafting) features such as the ability to draw lines, circles, rectangles, ellipses, arcs, curves, polygons, text and dimension lines. These are the features you need when you want to draw a site plan or a cabinet design or a plumbing or electrical layout or anything else. With general CAD features, the possibilities are endless on what you can draw with Drawing Board. See examples here on what can be done with Drawing Board.

How Drawing Board is Installed

A demonstration version of Drawing Board is included with each program that includes the Drawing Board window. As an example of the demonstration limits of the Drawing Board window, in Rhvac you can draw as large a floor plan as you like, but the load calculations will only be done for the first three rooms you draw, and the rooms will be limited to certain dimension restrictions. Once you purchase a license for Drawing Board, the drawing window will be 'unlocked' and load calculations can be done for all the rooms you draw on a drawing, no matter how large the rooms are.

Advanced Features

Drawing Board includes many advanced features. Here are a few of them:

As you can see below, Drawing Board can be used for more than drawing basic floor plans and duct systems. The drawing below illustrates using Drawing Board to embellish a drawing complete with furniture, appliances, landscape items and even cars in the garage. All the objects in the drawing below were just dragged and dropped into place. It is very easy to win more clients by offering full architecturally correct drawings.
