Create new product

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.

External dimensions of the object in millimeters (mm).

The Height parameter is only relevant for objects in rectangular ducts.

Dimensions of the duct for which the object is determined.

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.

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. Determine ID for pen assignment Close all dialogs. Select: Format Project's Pen, Layer, Font Setups The dialog appears: Project Properties. Activate: Pen Click Configure.... The dialog appears: Pen table. Search for the appropriate pen. 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. Identify existing layer numbers Close all dialogs. Select: Format Layers... The dialog appears: . Deactivate: List only those in use The list shows all available layers regardless of whether they were used in the model or not. 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

Link to an external document that is associated with this product, such as a PDF file, an Excel spreadsheet or text document. If a product contains a link you can open the document in the model. The application possibilities are endless.

Examples

• Data sheets with technical specifications of the object
• Bill of materials for composite objects
• Images

Syntax

General principle:

• Start with a semicolon ;
• Enter the full path to the document.

Examples

Storage	External info
in the file system	;C:\documents\armature devices\Pump.pdf
on the Internet	;http://www.beispiel.de/downloads/Pump.pdf

Application

If you have assigned a document to the object, you can access it within the model:

1. Select the object by clicking .
2. Click . The context menu appears.
3. Select: Show product sheet...
   The document opens within DDScad in a separate window.

Resistance coefficient of the object.

Data record describing the pressure loss of this component for different switch positions. The values can be found in the details from the manufacturer.

Setting	Description
empty	No throttling of the air flow by this component. The component is included in the pressure loss calculation only in terms of the value in Zeta.
Syntax as a data record	Continuous line separated by a semicolon (;) or whitespace.
	1st place	n	Number of data pairs d1…dn (maximum 100)
	2nd to nth place	a	Incrementing of the switch positions on the object as a number (0;20;40;...) or with a unit (0°; 20°;40°;... ).
	from nth place	b	Associated Zeta values for the switch positions in the same sequence. Decimal places separated by a point (.)

Value for the definition of a variable parameter in the symbol. The setting only applies when using a symbol with variable size.

Value for the definition of a variable parameter in the symbol. The setting only applies when using a symbol with variable size.

Data set for describing the natural sound generation of this component. The values are taken from the manufacturer's The values are taken from the manufacturer's specifications.

Syntax

Setting	Description
empty	No natural sound generation by this component. This situation does not occur in reality. The calculation result is unrealistic.
Syntax as record	A continuous line notes a series of data pairs (d) from volume flow (Q) and the associated sound power level (LW) for each switching position (n). For components without setting option, define only the series n1.
	n	Sequence number of the switching position. The series of the first switching position (n1) contains the values of the fully opened component. The series of the last switching position contains the values of the fully closed component.
	Q	Volume flow in liters per second [l/s].
	LW	Associated sound power level in decibels (dB).

Data set with correction factors resulting from the difference between calculated and measured sound power level for the various standard frequencies. The values can be taken from the manufacturer's specifications.

Syntax

Setting	Description
empty	Uncorrected reproduction of the values stored in Sound generation.
Syntax as a record	Correction factor for each standard frequency as a continuous line. Component with identical values in all switching positions A series with the values for the respective standard frequency, values separated by semicolons. Component with variable values at different switching positions In each case a series with the values for the respective standard frequency with open and closed state of the component. The values of the intermediate switching positions are interpolated. Separation of the values of a series by comma. Separation of the series by semicolon.

Data record describing the damping effect of this component for every standard frequency. The values can be found in the details from the manufacturer.

Syntax

Setting	Description
empty	No damping through this component.
Syntax as a data record	Reduction of the sound power level in dB for each standard frequency. Write the values as a continuous line separated by a semicolon.
