NVPartMaker

Now you are able to use any kind of air terminals and duct accessories to perform a sound and pressure calculation using Naviate’s Duct Acoustic. For the calculations to work, each item needs to exists in a database – a *.cdb-file.

The calculation looks at following parameters; Type, Manufacturer and Model. These three parameters create the unique key for each object and will make Naviate’s Duct Acoustic work properly.

NVPartMaker is a stand-alone installation for Revit, made for adding sound and pressure data on items and creating your own databases.

You have the option to start PartMaker from either the project or family file. Before you start you need to save the *.rfa family in a folder where you find it again. It doesn’t need to be the permanent place at this moment.

Catalog Root Folder: Determines where your Root Folder is to be placed.
Choose a place to create your database and library, somewhere on your disk or on a shared server. Beneath this folder PartMaker will automatically create needed folders.

Family File:  Find the *.rfa family, choose it and click Open. To be able to create a library of objects, PartMaker will now copy in your family in the folder. The *.rfa file will be placed in the folder that response to the System Type dropdown.

Catalog: This is the name of the cdb-file, just type in the wanted name. If the catalog folder has existing cdb-files these will be shown in the drop down.

Manufacturer: Determines the name of the manufacturer.

Model: The model name of the object.

Category: Determines which category the object belongs to in the cdb-file. This is for the sorting in the HVAC dialog.

System Type:  Adjust to edit for correct system type. Note that the connector is not edited with this change.

Use combined diagram for all Family Types: If there is a family with multiple types in it and all of them uses the same sound- and pressure diagram you need to use this checkbox.

In the window in the middle of the dialog you see the picked object by its type name. The objects type parameter is lined up in columns. Each field is editable and you can copy a row using
Ctrl-C/Ctrl-V and then easily create new types.

It is not unlikely to end up with a different amount of types for each family if you compare the project with the database. At the left border there are three different ways of loading these types in to the dialog.

For this to work, following three parameters is needed; Type Name, Manufacturer and Model.

Load from Catalog: Load the types from the chosen catalog.

Load from Family file: Load the types from the chosen family.

Load from Project: Load the types of the object from the project.

Delete Row: Lets you delete a row – and therefore also a type – of the family.

In the lower part of the dialog you find the place where to add the pressure and sound data. At first you need a diagram of the technical data for the air terminal.

Paste Image: Pastes the diagram for the technical data. Use your favorite image tool to capture an image, use Paste Image to insert the image as a background for the diagram definition. Mark up the boundaries of the diagram by clicking on two diagonal corners.

Undo: Undo what you just did.

Clear: Deletes all of your inserted data.

 

The three ribbons

Boundary: Set the boundaries for the X and Y axis by setting its min and max values. You are also able to change the units of each axis if needed. The boundaries are always marked by a red square.

Pressure Curves: Add a pressure line by click on two points on the pressure line in the image. The function extends your line to the borders so you don’t need to think about it.
If the terminal has a built-in damper there will be multiple pressure lines. By clicking the plus button you can add more curves. By clicking at the name you can easily edit it. If you have multiple curves you can see the marked up line by its dashed line.

Sound Curves: The most important point of the sound curve is where it crosses the pressure curve, therefore the continuation of the sound curve is not as important in the example below. You can see the marked up line by its dashed line.

Correction Factors: Input for the correction factors for the object.

Attenuation: Input for the attenuation for the object.

Hide: Hides the dialog box and allows you to zoom and pan.

Convert Cdb -> Csv: Use if you have a cdb file and want to convert it to a csv file using the Windows 1252 for a text encoding compatible with "ISO 8859-1".

Convert Csv -> Cdb: Use if you have a csv file and want to convert it to a csb file.

Load: Load an already saved cqdiadef file and continue working on this.

Save: We higly recommend you to save all of work in a cqdiadef file if you want to go back and edit your technical data with input and curves etc. By using Load you can choose among your previously saved cqdiadef files and continue working on it.

Export Csv: Export your values from the dialog to a csv file.

Export Cdb: Export your values from the dialog to a cdb file. A cdb file is what is needed for the function HVAC to work.

Close: Close the dialog.
