Starting a New Project

Top  Previous  Next

This tutorial will teach you how to properly start a new Design Master HVAC Project.

Before starting a new project in Design Master HVAC, it is necessary to setup your drawings. This process varies between companies. Typically it involves setting up the title block, inserting xrefs, and setting scale factors. It is beyond the scope of this tutorial to teach you how that is done in your company. If you have questions about this, please see your CAD Manager or the person responsible for setting up projects. However, there are two tasks that are part of the typical project setup that will not be part of this tutorial that we want to highlight:

1. It is necessary for the drawing you are working in to be saved in a project folder. Each project needs to be in a separate folder because all of the drawings in a common folder are assumed to be in a single project and therefore share a single Design Master HVAC database. For the introductory tutorials, the files for each tutorial are in a different folder. The result is that each tutorial is seen as a separate project.

2. The AutoCAD system variable DIMSCALE needs to be set correctly. Text and blocks are sized accordingly to this variable. In this tutorial, the DIMSCALE is set correctly for you. You can read more on our website about how to set DIMSCALE (http://www.designmaster.biz/Support/QandA/HowtoSetDIMSCALE.html).

To start this tutorial, start AutoCAD and open the M1.dwg file in the Start New Mechanical Project tutorial folder. Your drawing should look like this:

For the first step in starting a new HVAC project, go to

DM HVAC arrow Start New HVAC Project

The Start New HVAC Project dialog box will appear as shown below.

start_new_HVAC_project

Press the Select City button. The Select City dialog box will appear as shown below.

select_city

For the purposes of this tutorial, please select the City Group "WA" and the City "Seattle, Int'l Airport". Press OK. You will be returned to the Start New HVAC Project dialog box, which will now match the one shown below. (Note the section highlighted in blue will have changed).

start_new_HVAC_new_city

Type "Tutorial" in the Project Name field and press OK. Design Master HVAC will initialize the project; this will take a few seconds.

Next, you will insert the alignment point. The alignment point is used by Design Master HVAC as the origin for its coordinate system. It should be set in the same location relative to the building in each drawing.

You can read more about the alignment point in the online documentation.

To insert the alignment point, go to

DM HVAC arrow Insert Alignment Point

Design Master HVAC will ask you to specify an insertion point. Click so the insertion point is at the lower left hand corner of the building just outside the lobby, as shown below.

set_align

Design Master HVAC will ask you to specify the rotation angle. The alignment point arrow should always point in the direction of north on the drawing. For this drawing, rotate the arrow until it is pointing up towards the top of the drawing as shown below, then click. For future projects, this direction will not always be up on the drawing. The direction will not always be the same on every drawing in a project.

Congratulations! You now know how to start a new HVAC project using Design Master HVAC.
