A question that seems to be posed by companies when
they first look at or test out the 30 day trial of the
AutoCAD Plant 3D software is “How do I add Parts to my
spec?” I thought this would make a great topic to share
with everyone interested in the Plant portfolio of
products.
Let me start by explaining that Plant 3D’s pipe routing
features are spec driven. The specs that drive your
design can be loaded, modified and even created to meet
the needs of your design. This is accomplished by
opening the Specs and Catalogs Editor that is included
with the program.
Once opened (shown above), you will notice there are
2 parts in the welcome screen. The left side allows you
to “Create”, “Open” or even “Create from an existing”
Spec; while the right side allows you to “Open” or
“Create from an existing” Catalog. The Catalogs carry
all information such as pipes, valves and fittings per
the associated standard. The specs are a filtered set of
components, sizes, materials and rules based on the
information pulled from the catalog. Specs can be
modified or created any time throughout the project.
Plant 3D comes with several catalogs and default specs
while providing the flexibility to revise them to fit
your specific project needs.
For this example, we will add a 2” gate valve to the
Sample Project “Sch 40 PVC” spec. To start, we will
click on “Open” under Catalog to bring up the Open
Catalog dialog box. We will select “ASME Valves
Catalog.pcat” and choose open (shown below).
Once opened, we will use the filtering tools to find
a similar valve to start from. The Catalog Editor (shown
below) can be found on the top right tab and is divided
into segments for optimal control.
The Tools (middle) section filters items against the
selections made here such as Part Category, size and end
connections. Once you have made your selections, the
parts displayed in the Catalog Parts Table (bottom)
section have been reduced. You can continue filtering
more in this section by using the drop-down lists across
this section’s header. Once you have found the part you
wanted, select it and the parts properties are displayed
in the Common Properties (upper) section.
We want to make the following selections in the Tools
section: (shown below)
Part catalog = Valves
Main end connection = SW (socket welded)
Size Range = From 2” and To = 2”
Now that the filtered results are minimal, select the
only 2” gate valve with the 150lb pressure class. This
will display part information in the Common Properties
section.
Important: Do not change
any information to this part! We want to
create a copy by selecting the “Add Copy to Catalog”
button on the Tools section. We now see an identical
part in the list at the bottom. Once selected, we want
to move up to the “Common Properties” section and scroll
down under the General Properties heading and enter
“PVC” in the materials filed (shown below).
At this point, we want to click Apply and then, Save the
catalog using the File pull-down menu. We have now
selected a part, copied the part, modified the material
value and saved the catalog.
Let’s click on the “Reset” button in the “Tools”
section. This removes all applied filters. Now, let’s
scroll over in the bottom section until we see material,
click on the pull-down menu for material and select
“PVC” (shown below).
This will filter to the newly modified part. We will use
this to create our “Sch 40 PVC” gate valve, so select
the part in the bottom section. The next steps will
focus solely on the “Common Properties” section. (This
is an example part; I suggest when creating a part, cut
sheets of the required part should be used for
accuracy).
First, click on the “View Large Image with Dimensions”
link under the thumbnail image. This will bring up a
detail of the related dimensions (shown below).
Note: The image can remain open, resized and moved
around while editing the parts values.
Now that we understand where the dimension values are
represented we can make our changes. Uncheck the box
under the “Part Geometry” heading. Hovering over the
fields will display additional information about the
dimension and its value.
We want to make the following changes under the
following headings:
Part Geometry: (there are multiple
fields for each below – change both)
L1 = 0.925
L2 = 0.925
I1 = 0.875
I2 = 0.875
L1 = 0.925
L2 = 0.925
I1 = 0.875
I2 = 0.875
General Properties:
Short Description:
Gate Valve
Long Description (Size): GLUED
GATE VALVE, 2" ND, 150 LB, SW, ASME B16.10
Long Description (Family): Glued Gate Valve, 150 LB, SW,
ASME B16.10
Port Properties:
Matching Pipe OD1:
2.695 (this matches schedule 40 Pipe OD)
End Type 1:
PSW (this represents a glued connection)
Engagement Length 1:
.875 (this represents a glued connection)
Matching Pipe OD2:
2.695 (this matches schedule 40 Pipe OD)
End Type 2:
PSW (this represents a glued connection)
Engagement Length 2:
.875 (this represents a glued connection)
Click the Apply button and Save from the File pull-down
menu. We next want to add the part to the Project “Sch
40 PVC” spec. Click on the Spec Editor tab in the top
right (shown below) and open the Sch 40 PVC.pspx spec.

Once the spec is opened, switch back to the Catalog
Editor Tab, make sure we have the new part selected,
then click on the “Add to Spec” button. This will bring
up an “Add to Specs” dialog box. Click the check box
next to the Sch 40 PVC spec (multiple specs will be
listed if multiple specs are opened) and choose OK.
This will add the part to the desired spec which we can
now “Save As” into the SpecSheets folder of your current
project (shown below – actual location will be
determined by you upon creating your project).
So let’s recap:
We copied an existing part in an existing catalog
We modified the part in the existing Catalog
We added the new part to a spec
We then saved the spec to our project specs
Hopefully, this has been helpful in getting to know the
Specs & Catalogs Editor and the true power and
flexibility in making parts based on required cut sheets
pertaining to your projects. Let us know if this article
