Fluid Part

Use the Fluid Part tools to designate or create the fluid parts in your model geometry.

Location: Dispensing ribbon, Fluid Part icon

A fluid part is a designated volume that dispensed fluid may flow into. You might want to fill the fluid part entirely with fluid material, or you may want to merely indicate areas that dispensed fluid might reach.

Designate a Fluid Part

If your model geometry contains one or more parts that represent a fluid part in the finished product, use the Fluid Part tool to designate them as fluid parts.

  1. Click the Fluid Part icon.
  2. Select the fluid part in your model.
    The selected part is displayed in transparent red.
  3. Optional: Change the Environment Temperature if necessary.
  4. Click the Gravity Direction icon to set the gravity direction with respect to the part.


  5. Use the microdialog options to flip or rotate the model to align it with the gravity direction. The gravity direction affects the behavior of the liquid as it is dispensed into the model and during solidification.
    Microdialog option Description
    Rotate the model with the Move tool.
    Pick a surface to align its normal with the gravity direction.
    Flip the model vertically to switch the model between the positive and negative Z direction.

Create a Fluid Part

Select one or more voids in your model to designate them as fluid domains.

  1. Click the Create Fluid Domain icon.
  2. If you have not yet selected a housing part,
    1. Manual Selection will be selected by default in the guidebar. Select an undefined part that has a void that you want to fill with fluid material.
    2. Optional: Control-click to select more undefined parts with voids to fill. Shift-click to deselect.
    3. Click the button to confirm.
      Voids in all selected parts appear red.

    4. Optional: Use the microdialog to change temperature of the working environment.
    5. Right-click and mouse through the check mark to exit, or double-right-click.
  3. If you have already selected a housing part,
    1. Housings will be selected by default on the guidebar. A void in one of the designated housing parts will appear red. All other voids will appear gray.
    2. Optional: Control-click to select more voids. Shift-click to deselect.
    3. Optional: Use the microdialog to change temperature of the working environment.
    4. When you are satified with the selections, click the button to accept and close the tool.
