Smooth, Smudge Deposit, Remove & Erase with options to raise, lower or blend the changes.The Sculpting tool lets you interactively modify 3D designs using the sculpting tools with control over brush size and strength, plus options to, This function sets Aspire apart from typical computer modelers as this type of dynamic editing cannot be replicated using standard surface or solid CAD/CAM modeling programs. The component brush option can be used as part of the deposit and remove tools, where the brush will leave an impression in the composite model that simulates the pushing of the component brush through the surface when dragging, and a stamping effect when clicking! The Sculpting Tool allows for the option of using any model as a brush for sculpting, giving you an unlimited selection of brush styles that suit your needs. You can also use the dynamic rotation option that intelligently rotates the brush in the direction that you are sculpting. The custom brush allows you to easily add texture and detail to your composite model. The option to Preserve Transparency limits sculpting changes to only be on the 3D model surface and not 'bleed out' onto the surrounding flat plane.
