Sometimes you need to determine a liquid volume of a container, but the shape may make it difficult. In the tutorial, we will determine the liquid volume of an existing cup with only a single feature.
Step1
The cup model is shown below, and also in cross-section.
Step 2
We start be creating a Reference Plane that will determine the top of the liquid level mark. The Plane was made as offset from the base (below).
Step 3
Next, we create a Boss with the sketch plane on the new Reference Plane. Select the inner face and select Convert Entities.
Step 4
When the sketch is created, select to Extrude using Up To Body and pick the model.
Step 5
The trick is to un-select the Merge Result button. This will create a feature (Boss-Extrude 3) that is not attached to the actual model.
Step 6
Now in Evaluate, select Mass Properties. Delete the selection called Part, and select the feature just created. The Mass Properties results will now only be for the un-merged featured. This is your liquid in the model.
Step 7
You can suppress the feature and save your model.
Have fun and enjoy.
