7.6.11. Plant 3D connection elements in secondary steelwork
On this page
In AutoCAD Plant 3D, the automated placement of connection elements is only possible to a limited extent within the standard range of functions. This article explains the limits of manual placement and shows which options SuCri Module 3 offers in Plant 3D.
Prerequisites
- Installed version of AutoCAD Plant 3D.
- Access to the Secondary Steel pipe class.
- For the automated connections: SuCri Module 3 for Plant 3D is installed (see 2.2.3. Module 3 (P3D)).
Step-by-step guide
- Taking stock of the standard components: Check in the Secondary Steel pipe class which components are available for your current project. In the standard configuration, you will only find a limited selection of components here.
- Manual placement (without SuCri): Select the desired component from the pipe class and position it manually on the corresponding steel structure. Alignment and spacing must be defined by hand.
- Placing connections with SuCri Module 3: With Module 3 you place connections between profiles using the connection commands of the SuCri tool palette: Collision (T), Free end (I), Crossing (X), Joint (V), 3 corner (Y), 4 corner (K) and Parallel (P). After the profiles have been selected, SuCri offers the matching connections from the manufacturer catalog (see 7.4.3. Where can I see which connections are available? (Plant 3D)).
Important notes
- Range of functions: Module 3 places steel connections of the seven connection types using the components of the respective manufacturer catalog. In addition, "Validate connections" (
SuCri3ValidateConnections), Export anchor list (SuCri3ExportAnchors) and Update item numbers (SuCri3SetItemCodes), among others, are available in Plant 3D. - Comparison: Users of Advance Steel (ADVS) are used to a high degree of automation; in Plant 3D this is only achieved through add-on modules such as SuCri Module 3.
Troubleshooting
-
Problem: Connection elements are not recorded correctly in the BOM.
Solution: For manually placed components, check whether they are stored in the Secondary Steel pipe class with all necessary metadata. For SuCri profiles, rewrite the item numbers withSuCri3SetItemCodes. -
Problem: No connection is offered.
Solution: See 7.4.2. How can I work with profiles that are not supported and 7.4.3. Where can I see which connections are available? (Plant 3D).
