Calculate the Mass of a Part Model
General
- You can calculate the mass and moments of inertia for a part model model with the
Mass function. - After the calculation, the center of gravity mark is added to the model, which is also visible in the model's feature tree under the item Configurations:
Gravity center followed by the weight of the model.
- You can hide and show the gravity center of the model by pressing the G key, which also hides all other auxiliary geometry (e.g. guide lines, auxiliary planes and cross-sections).
- In a drawing, you can get the gravity center symbol
for the projection you want by selecting the projection and the function 
Properties and selecting 
Gravity center. - The text of the gravity center symbol in the feature tree turns red when the weight calculation needs to be updated.
- Zoom to the gravity center symbol by selecting Gravity center from the feature tree and select the context-sensitive function Zoom or press the Z key.
Basics of Part Model Mass Calculation
The calculation of the weight of a part model is based on the geometry of the model, from which the program obtains the volume of the model and the density of the model, which is specified in the item data of the part model (on the Purchased Item Data tab)
- If no density is specified in the material data or item data, the default density is used.
- The default density is the steel density of 7850 kg/m3.
- The default density of the main raw material used by the company can be set in File >
System Preferences > 
Mechanical Engineering > Mechanical tab, in the field Density.
Note that this setting affects all workstations using the same server.
- If Vertex G4 is connected to the product data management system Vertex Flow, the mass calculation gets its data from the item in Flow.
Calculate the Mass of a Part Model
- Select the function Mass or
- select the context-sensitive function Other Exports > Mass Calculation.
- The program performs the mass calculation and
- opens the dialog box Mass Calculation.
- select the context-sensitive function Other Exports >
- Select the options for mass calculation, if necessary.
- Mass Calculation Dialog box.
- The option
Do not calculate hidden is not available for a part model.
- If necessary, select Apply to perform the calculation again.
- If necessary, you can copy the result of the calculation by painting the result and using the function pair Copy - Paste.
- Click OK to exit the calculation .
Calculation results
The result of the calculation is saved in the model and displayed
- In the feature tree after configurations Gravity center XXX kg.
- In the part model archive data.
- In the archive data of the part model drawing.
The program calculates the location of the gravity center in relation to the absolute origin point of the model, unless the measuring point of the gravity center is separately selected from the model with the mass calculation function Click Origin Point.
You can also update the result of the calculation by selecting Gravity center in the feature tree and the context-sensitive function Refresh.
