3D:Inflated Objects Tutorial

Inflated Objects

• Inflating simulated objects are fairly advanced since it requires dealing with the Simulation Properties.

1. Download the file Inflated Capsule.zip (56 kb) and open it on OptiTex PDS.
2. Download the file Floor.zip (25 kb) and load it to the 3D Model window.
3. Setting up Simulation Properties:
   1. Set the Gravity to '0' to keep the object from moving.
   2. Check the Implicit Only option.
   3. Check the Use Pressure option and set the value to 10.
4. Place Cloth and Simulate Draping.

• Working with Large pieces - When simulating large pieces, set Resolution to be lower (values 2-10).
• When working with Pressure start with low pressure value and raise it gradually.

Troubleshooting

The simulation stopped but the object is not fully sewn

Simulation of inflated object may take longer to solve. Click Simulate Draping again to run the simulation solver again.

The simulation stopped and an error message popped saying that the simulation has failed

• Use Implicit Only solver to run an accurate simulation.
• Lower the Pressure value.
• Set higher/lower Resolution for the simulated pieces, Clear the 3D Model window and run simulation again.
• Each piece has a definition of inside and outside. When placing pieces they should all be heading outside. Make sure the pieces are heading outside by selecting a piece and changing its Thickness – the thickness should change on the 'inside' direction.
