Context: An alternative method of adding and editing attribute values is
Link Spreadsheet available in
Civil Engineering 3D Design.
With a valid license for
Civil Engineering 3D Design
and the appropriate assigned role, the system reflects in the
BIM Attributes panel any changes that you make using
Link Spreadheet. Likewise, the spreadsheet that
you create with
Link Spreadsheet reflects any changes that you
make in the
BIM Attributes panel.
Add or Remove a Standard Extension
You can add or remove a standard extension that is assigned to
a type of object.
-
From the
BIM section of the
action bar,
click
BIM Attributes
.
The
BIM Attributes lists the possible extensions
that comply with the standards specified in
.
The
BIM Attributes panel groups attribute sets
into individual expandable sections.
-
Select an object.
-
In the
BIM Attributes panel, click
to open the
Select Extension to add section.
A list of extensions that matches the type of object is
displayed.
-
To add extensions:
-
Select the
attribute set
of interest.
An expandable section is added.
-
Click
to expand a section and display more information.
-
Enter the required information in the boxes.
-
Click to collapse a section and remove it from the display.
You can add as many extensions as you need.
-
To remove extensions, select the extension, and click
.
The extension is automatically removed.
Note:
In some cases, models are assigned undesirable extensions. If
extensions are disabled in
but appear in the
Extensions list, they are red-colored and
placed at the end of the list.
Edit and Synchronize Attributes Values
Quantity take-offs (Qto) and Property sets (Pset) can be
exposed as parameter sets in the
BIM attributes panel and you can edit them.
Synchronization status between these parameters and the PLM attributes are
displayed in the
tree.
In the
BIM attributes panel, the attribute sets sections
are attributes from the PLM level and they have an impact on geometry. For the
values of the
Ifc Window and
Ifc Window common sections are specifications
that can have an impact on geometry.
The role of Quantity take-offs (Qto) and Property sets (Pset) is described below:
-
A Property set (Pset) corresponds to specifications applied downwards to
drive the geometry. They are instanced under the External
Parameters node under the Ifc Window and Ifc Window
common sections of the BIM Attributes panel.
When you add a specification at the level of the PLM attribute, it is
duplicated on the parameter. This is a downward information impacting
the geometry. When the Pset drives the geometry, a dependency
relationship exists between PLM attributes and derived external
parameters.
You cannot modify external parameters that are driven by the PLM
attributes.
-
A Quantity take-off (Qto) contains internal or standard parameters and is
instanced under the Parameters node in the tree or the Ifc Window base
quantities section of the BIM
Attributes panel.
It is a group of accurate take-offs such as length, weight, and volume,
measuring the various sizes of a design object. A measure is set on a
dedicated parameter and you can change it directly in the BIM
Attributes panel, with formulae if needed. Then, the
information is propagated to the PLM attribute thanks to a Knowledge
rule. This is an upward information impacting the reference.
Before you begin: Make sure that parameter sets related to Pset or Qto exist.
-
Create a PLM object, a Window for example.
-
From the
BIM section of the
action bar,
click
BIM Attributes
.
The BIM Attributes panel opens,
- listing the possible extensions that comply with the standards
specified in .
- grouping attribute sets into individual expandable sections.
Notes:
You can see the object's attributes that are exposed
in the database. If you expand an attribute set section, Ifc
Window base quantities for example, by clicking , the PLM attributes editor is simple, with very few contextual
commands (only Copy, Cut, Paste). These attributes can also be seen via
the Properties dialog box when you right-click
the object in the tree.
-
Insert a 3D Shape (a skeleton representation).
External parameters or standard parameters are created
automatically in the skeleton representation when available.
You can decide to define the same attributes as the PLM
attributes'. The information is duplicated at the
External Parameters level of the
tree.
When synchronization exists between the PLM database and the design mock-up,
this symbol appears in the
tree:
. When there is no synchronization, the symbol changes
into:
.
-
Select the PLM object and click
Update
.
The information (3m) goes down on the 3D Shape. The
parameter and geometry driven by the parameter are updated accordingly. In the
tree,
the parameter turns green.
The Qto value (measures for height) is not updated in the
tree
(0m).
-
Right-click the Qto parameter (height) and click
Edit Parameter to
Edit formula or add a
Measure Between for example.
Notes:
You can decide to set the information either on
the attribute or on the parameter because there are two ways of transmitting
the design information:
- In one case, the specification moves down from the PLM
attribute and impacts the geometry (Pset).
- In another case, a measure parameter of the geometry is
applied onto the PLM attribute. In this case, a Knowledge rule is automatically
executed to move the information up to the PLM attribute (Qto).
Note:
The
BIM Attributes panel is intended to ease the
edition and synchronization of parameters. You can edit values of an attribute
set either by entering the values in the boxes directly or by using the control
buttons. You can also find the same contextual commands for edition as the ones
accessible from the contextual menu of the
tree
(Edit Parameters).
-
Click
to expand the
attribute set section and display more
information.
-
In the
BIM Attributes panel, change a Pset (overall
height for example) under the
Ifc Window section.
The parameter icon in the panel changes into
to show that the geometry is not synchronized. The same
status is reflected in the
tree.
In the panel, you can see the value of the PLM attribute in the
Overall width box.
-
In the
BIM Attributes panel, change a Qto (Area for
example) under the
Ifc Window base quantity section.
The new value of the parameter is automatically updated
in the
tree,
under the
Parameters node. In the panel, the symbol
next to the Area box changes from
to
.
-
Select the PLM object and click
Update
.
The Qto PLM attribute linked to the parameter is
automatically updated by the knowledge rule created by the system. The
Knowledge rule, connected to the PLM object, assigns the parameter value onto
the PLM attribute. The information is the same in the
BIM Attributes and
Properties panels and in the
tree.
-
To add parameter sets to a 3D Shape, click
.
You expose an extension as a parameter set on an object.
The changes made to the values are automatically reflected in
session and will be saved along with the product.
Detect Modifications in Feature Property Set and Update
From the R2021x FD02 release level onwards, when a BIM attribute has been changed on a
feature, the feature status becomes out-of-date. Then you can update your object
manually. This update is triggered after the modification of Pset or base extension
attributes only (Qto attributes do not impact the update status).
-
To type a GSD volume for example, click Define
Specification
from the Civil
Engineering section of the action bar.
-
Search for a type, Pier for example, in the Define
Specification dialog box and select your volume to type
it.
-
Click OK to validate the command.
-
Open the BIM Attributes panel and select your
volume.
The volume is seen as a Pier.
-
Change the Predefined type attribute.
A mask on the feature in the tree indicates the object requires an update.
-
In the Standard area of the action bar, click Update
.
Expose an Extension as a Parameter Set
From the
BIM Attributes panel, you can expose missing
parameter sets linked to some Pset or Qto Attribute sets.
-
From the
BIM section of the
action bar,
click
BIM Attributes
.
The
BIM Attributes panel opens.
-
The
BIM Attributes panel, click
in the header of extension collapsible sections to add
parameter sets to a 3D Shape.
As you expose an extension as a parameter set on an
object, it is inserted in the
tree.
For example, it creates a Skeleton representation with a parameter set, the
name of which is the one of the exposed Property set (Pset) or Quantity
take-off (Qto). Psets are exposed as External parameter sets (parameters driven
by PLM attributes) in the
tree.
Qto are exposed as regular parameter sets; in that case a Knowledge rule is
also created to make sure that PLM attributes are driven by the parameters.
Note:
When the property set is already exposed as a parameter set
in the representation, the button is dimmed and no action is triggered if you
click it.
Assign Object Types to Objects
You can assign an object type to an object.
