Create new product– Air Terminal

Example

Suppose you want to use a special object of this category in the model, but it is not available in the product database. In this case, you can create a new product and assign the desired properties.

Workflow

In the starting situation the object dialog is opened.

  1. Click ... . The product database appears.
  2. Switch to the filter to which a new product should be created.
  3. Select a suitable product Closedas a template. A product is suitable as a template if it matches in as many properties with the new product.
  4. Click . The context menu appears.
  5. Select: Duplicate
    The copy template is duplicated. The product number is generated automatically and the product description begins with the word Copy. You can edit the copy and customize the product properties.
  1. Select the copy by clicking . The context menu appears.
  2. Select: Change
    The dialog appears: Change Product
  3. Edit the data fields of the new product and click OK. The dialog is closed. You return to the main dialog of the product database. You can use the product in the current project.

Data fields of the product database

Alphanumeric string (maximum 15 characters) for unique identification of the object for the parts list. DDScad automatically suggests a character string when a new product is created. You can accept the suggestion or replace it with a number. DDScad prevents duplicate numbers automatically.

Character string (max. 256 characters) for a verbal description of the product. The text appears as a selection aid in the product database and in evaluations (parts lists, calculation reports).

Code to call a symbol that was created with DDScad and corresponds to the file name of a specified convention. The input becomes irrelevant if External symbol (2D;3D) refers to another symbol.

Dimensions for the beginning of a ventilation duct on the object. The ventilation duct adopts these dimensions.

The Duct height parameter determines the geometric shape of the ventilation duct.

Duct height Effect
= 0 The ventilation duct is round. The Duct width value corresponds to the diameter.
> 0 The ventilation duct is rectangular.

Code for representation in the rendered model.

Field for an individual text block of the part text with up to a maximum of eight characters in length.

GTIN / EAN (not used)

Numeric code fur using a pen for the representation in the model.

Setting Effect
0 The object is displayed with the pen that is the default for its object type.
≠0

The object is not displayed with the pen that is the default for its object type. The number corresponds to the ID of the pen in the dialog Pen table.

  1. Close all dialogs.
  2. Select: Format Project's Pen, Layer, Font Setups
    The dialog appears: Project Properties.
  3. Activate: Pen
  4. Click Configure....
    The dialog appears: Pen table.
  5. Search for the appropriate pen.
  6. To display the ID: double click on the name of the required pen. A message displays the code being searched for.

Numeric code for the assignment of the object to a layer.

Setting Effect
0 The object is assigned to the default layer of its object types.
≠0

The object is assigned to the inserted layer number that is available in its discipline. You can use existing or non-existing layer numbers. If you used a non-existing layer number, the layer will be automatically created by using the object in the project.

  1. Close all dialogs.
  2. Select: Format Layers...
    The dialog appears: .
  3. Deactivate: List only those in use
    The list shows all available layers regardless of whether they were used in the model or not.
  4. Enter the value in Number.

Text string for the name of the manufacturer.

Unit of measurement for inclusion in the parts list.

Code which is provided along with the object during an IFC export and enables the receiving system to assign the object to a class. The syntax is standardized: buildingSMART | Domain specific data schemas.htm

Faulty syntax
Correct syntax The object is exported with the entered code.

Settings for the mounting height which DDScad provides as selections when the product is called.

Syntax Description

empty

The default settings apply for objects of this type.
<Reference>;<Distance>;</ Lock Height:>

Specific settings for this product.

Selection of a reference line in the building to define the mounting height.

Code Reference
0 No distance to the selected <Reference>
Value>0 Distance to selected <Reference> in the direction into the room (e.g. below the ceiling, above the floor)
Value<0 Distance to selected <Reference> in the direction towards the outside of the room (e.g. above the ceiling, below the floor)

Setting for the behaviour of the object in the event that the height of the selected reference in the building model changes. Closed Example

Code Lock Height: Effect
0

DDScad checks changes in the height ratio between the object and the selected reference using the function Check and Verify Models.ClosedWorkflow

DDScad calculates a new value for Distance. The object ignores the change of the building model.

Reference to drawing files that need to appear instead of the once addressed in Symbol number. The referenced files must be stored either in the Project folder or in the USER folder.

You can use the following file types:

You can create the object using the geometric functions of DDScad. For use as a symbol in 2D and/or 3D enter in External symbol (2D;3D):

empty

No natural sound generation by this component.

This situation does not occur in reality. The calculation result is unrealistic.
