5 +The **Industry Foundation Classes** IFC specification is a neutral data format to describe, exchange and share information typically used within the building and facility management industry sector. IFC is the international standard for openBIM
6 +- [[source>>url:http://www.ifcwiki.org/index.php?title=IFC_Wiki]]
7 +
8 +Exports to the IFC format can be done in a BricsCAD version that supports conversion (BricsCAD BIM). This article is a step by step guide that will cover how the export is done. First, the model must be generated in an empty drawing. Create one under the category //3D //in the [[project browser>>doc:IMPACT Applications.Project Manager.Project Browser.WebHome]], as shown below.
9 +
10 +[[image:1.png]]
11 +
12 +//Figure 1: New 3D drawing//
13 +
14 +Before opening the drawing, go to the project folder. Download this [[attach:IFC Property Set Definitions.dwg||target="_blank"]] file for BricsCAD and paste it into the folder Project name/design/drawings/common drawings. Give this file the (% class="mark" %)exact same name(%%) as the 3D drawing that was just created (% class="mark" %)(erase the original)(%%).
15 +
16 +[[image:byt.gif]]
17 +
18 +//Figure 2: Replacing the dwg//
19 +
20 +Open the empty drawing and generate the elements that will be included in the export by using the (% class="mark mark" %)//generate//(% class="mark" %)// plan//(%%) command. Configure your selection of elements and be sure to select the //AutoCAD solid (IFC)// option found under //setup//. This allows export to the IFC format.
21 +
22 +[[image:solid.png]]
23 +
24 +//Figure 3: Generate the elements as IFC-compatible solids //
25 +
26 +Add information about the elements to include in the export. This is done through the "add property set" command found under the "BASE" tab in BricsCAD.
27 +
28 +[[image:ps.png]]
29 +
30 +//Figure 4: Add property set...//
31 +
32 +Make the export from BricsCAD file menu as shown in the image below.

40 +
41 +The elements in the export can be colored in two different ways, both of which depend on how the variable **[[SOLIDCOLORBYMATERIAL>>url:https://wiki.impact.strusoft.com/xwiki/bin/view/IMPACT%20Applications/Standard%20Admin/Components/SOLIDCOLORBYMATERIAL/]]** is configured. Either, the elements get the color based on AutoCAD's layer //0//, which by default is black. Or, the elements will be colored based on its material color. Materials are configured in Standard Admin with an exact color (RGB value).
42 +
43 +With the variable value set to //0 //(turned off) the model will inherit the color of layer 0 - black.

46 +//Figure 7: IFC model colored by layer 0//
47 +
48 +With the variable value set to //1 //(turned on), the elements/components will inherit the color of its material. In the example below the walls have a grey color from the concrete and the CIMs have a slightly darker gray which makes them visible when the model is viewed as somewhat transparent.

54 +
55 +A huge advantage with exporting IFC from BricsCAD, and not from AutoCAD, is when opening the IFC model in an IFC viewer (in //Figure 9// Solibri Model Viewer is used) that the elements will be presented in a tree-structure that categorizes element in buildings, floors, and types (see //1 //in //Figure 9//).
56 +Similar to AutoCAD, the properties of all elements can be found under the IMPACT tab (see //2// in //Figure 9//).
