To Create Specs

Create a spec sheet.

Open a Spec File

1. On the File menu, click Open Spec.

   Alternatively, click the Open icon from the toolbar or click Open Spec from the spec dropdown list.

2. In the Open dialog box, select a spec file (for example: C:\AutoCAD Plant 3D 2026 Content\Specs\CS300.pspx).
3. Click Open.

The spec file opens and displays a spec sheet.

Create a New Spec

1. On File menu, click New Create Spec.
2. In the Create Spec dialog box, click the [...] button and browse to the folder where you want to save the spec file. Append a file name for the spec file to the folder path (for example, C:\AutoCAD Plant 3D 2026 Content\Specs\New_Spec.pspx).
3. In the Spec Description box, enter a description.
4. (Optional) In the Load Catalog list, choose a default catalog to load with the spec file (for example, ASME Pipes and Fittings Catalog.pcat).
5. Click Create.

A new spec displays. The corresponding catalog is displayed in the Catalog Browser when a new specification is selected. You can now add piping components from the catalog to the new spec.

Create a Spec from an Existing Spec

1. On File menu, click New Create Spec from Existing Spec.
2. In the Create Spec From Existing Spec dialog box, under Source Spec Name, click the [...] button.
3. In the Open dialog box, do one of the following:
   • Browse to the existing spec file you want to duplicate.
   • In the File Name box, enter the path to the file (for example, C:\AutoCAD Plant 3D 2026 Content\Specs\CS300.pspx).
4. Under New Spec Name, enter a name for the file.
5. Under Spec Description, enter a description.
6. Click Create.
   Note: You cannot use File Explorer to rename spec files. The PSPX is a package file that contains a named reference to the PSPC.
