Details on Quantity Takeoff acc. to

Information on the Quantity takeoff dialog in the context of the Quantity takeoff workflow.

You are here:

Project tab ➤ Disciplines ... ➤ Workflows ➤ Quantity takeoff ➤ Analyse tab ➤ Quantity takeoff (Ventilation) ...

Configuration

Load configuration from external file

Opens an existing configuration in QCF format.

Save configuration to external file

Saves the current configuration to an external file in a directory to be specified by the user.
Attention: At this point, you only save the current configuration, but no takeoff quantities.

Default values

Resets the configuration to default values. This action cannot be undone.

Partial service

Name of the partial service. Components are assigned to a partial service on the basis of the LINEAR.TEC classification in the Kanalnetz.tec file. To ensure correct classification and assignment of partial services for quantity takeoff, only the original file should be used when dimensioning the ventilation network.

Quantity takeoff specification

The standard on which the quantity takeoff specifications are based.

Short text

Shows the set short text attributes with the assigned parameter alias. After you have activated a cell by double-clicking in the Short text column, you can change the order of the attributes using drag-and-drop or adjust attributes by clicking on .
Attention: The quantity takeoff takes into account the order of the attributes for the quantity aggregation or summation.

If you install components from the LINEAR CAD Browser, the associated short text can be included in the calculation of the quantity takeoff if you add the LIN_SHORT_DESCRIPTION parameter as an attribute for the short text, as a replacement for the part name).

Opens the Configure short text dialog, in which you can add or remove attributes to the respective partial service for displaying in the short text.

Bill of quantities

Recalculate quantity takeoff

Updates all calculations taking into account changes in the model. Click this button if, for example, you have changed the component material and want to see the results in the calculation. Changes in the configuration are taken into account and displayed in real time.

Show only positions with warning

Displays only positions with warning. Clicking on in the table opens the dialog with the quantity takeoff details of this position, where you can find information about the source of the error.

Item number

Select the item number range to be displayed in the quantity takeoff details. The item number will be taken over for the quantity takeoff details when exporting to GAEB.

Take cost classification into account when determining quantities

Enabled: Components with different cost groups but otherwise the same properties are divided among several items and associated component quantities are summed up separately by cost group.

Special cases related to cost classification:

  • Revit Treats insulation of an air duct or pipe as a separate component. Therefore, for the cost group of the insulation, a separate (possibly also different) parameter value can be set in the quantity takeoff and written back to the model.

  • Sections of an air duct are automatically assigned the cost group of the associated air duct. The value cannot be changed.

With title suggestions

Enabled: Groups the items under the titles of the partial services.

Deactivated: Displays all items as a sequentially numbered list.

Select corresponding components in project

Selects all components in the project that belong to the currently selected item.

Export partial quantities to long text

Enabled: If there is a parameter value for LIN_LONG_DESCRIPTION, long texts of components are taken over and exported. Use this option, for example, for a product-specific call for tenders.

Export

Opens the file explorer, where you can save the current calculation in the formats GAEB (*.x81), BIM-LV (*.mmc) and Microsoft Excel (*.xlsx) under a file name to be defined in the desired directory.
Note: When exporting to GAEB, catalog references from the quantity takeoff details are created for the item number, reference level, system and cost classification, which can then be used for further commercial processing, such as quantity calculation and cost documentation.
Table column Description
ON Display of the ordinal number.
Title or short text Display the titles (if the With title suggestions option is enabled), and the short texts of the respective partial service, according to the short text attributes set in the Configure section. Clicking on opens the quantity takeoff details of the respective item.
Quantity Quantity takeoff of the respective partial service determined in accordance with the standard.
UM: Unit of measurement Unit in which the quantity takoff of the respective partial service was determined and specified.
CG: Cost group Display of the cost group. The cost group was either assigned manually in this dialog or automatically read out from the parameter value of the associated components.
Clicking in a row of the table highlights the corresponding partial service in the configuration.
