Command line: TABS > IFC

Tool for viewing IFC (Industry Foundation Classes) files. IFC is used as a format for the building information model BIM (Building Information Modeling):

Model Import

1. Run the import command:

· The Import button in the main menu of the IFC toolbar.

· The Import button in the tree of elements.

· Command line: IFCVIEW3D.

2. Select the IFC file and confirm the selection.

The file will be analyzed and imported into the nanoCAD environment. The loading time depends on the computer’s power and the file’s complexity.

3. After import, a tree of elements will be available, united into one project. Additional commands will become available. When importing several models sequentially, several projects will be displayed in the tree.

Main Menu of the Toolbar

Depending on the selected element in the tree, the following commands become available:

* Import – the command opens the dialog for selecting a file to import.

Delete – the command deletes the selected element and all its descendants from the model.

Update IFC – the command updates the model tree.

*Drop*-down list for selecting a group.

Grouping – the command opens the Grouping dialog to set up the grouping of objects in the element tree.

Show/hide in model – the command controls the display of the selected element and all its descendants. You can also control the display using the switch to the left of the element name.

Show/hide only this – the command switches the display between the selected element and the elements of the same parent.

Show on drawing – the command focuses and selects the object in the drawing (in the model space). IFC import settings – the command opens the IFC Import Settings dialog.

NOTE The commands of the element tree context menu duplicate the commands of the toolbar’s main menu.

Grouping

By default, elements in the tree are grouped in the following sequence: Project – Site – Building – BuildingStorey – Type – Name.

It is possible to select another grouping method (from the grouping selection list) or assign a user-defined one.

Standard groupings: Default, Type, BuildingStorey, Layer.

To view the composition of a grouping, select the required grouping and click the CAD software IFC Viewer 19 Grouping button. In the Grouping dialog, the fields will display the parameters of the selected grouping. To create a user-defined grouping, change the composition of the fields and click the OK button.

By default

User-defined

NOTE When creating a user-defined grouping, elements are additionally grouped by the title of the name. The title of the name is the text of the name from the first character to the first space (or end of line).
