With the Live Parts™ Add-in, you can create forces that act upon your design as it grows in Live Parts.
You can create forces using the method outlined below.
- Select Force in the Live Parts Add-in toolbar.
- Use the Force Type drop-down list to select the type of force (linear, pressure, or rotational).
- Input the values for each directional component of the force (X, Y, and Z) as numbers or expressions.
- (Optional) Instead of Step 3, click the Direction dropdown menu and choose Selected entity to input the force direction by selecting an entity (e.g. a line) in your assembly.
- Click the Surfaces box and select the relevant surface(s) in your assembly to which the force will be applied.
- Select the Force application method (under Parameters) to specify how the force will be applied to the chosen surface(s) - push, pull, or both.
- Click the Magnitude box (under Parameters) and input the magnitude of your force in Newtons.
- Click the Checkmark on the top of the force menu to accept the changes.
- Select surfaces for your force that are coincident with fill, exclude, and contain zones.
- Specify the direction of the force and the force application in a way that makes sense in the context of your model. For example, if you select the top surface of a beam for a force and input the force direction is "downwards", it follows that the force application should be "push" (i.e. the force is pushing the beam downwards). In the same example, if you input the force direction as "upwards", then the force application should be "pull" (i.e. the force is pulling the beam upwards). For simplicity you can specify the force application as "both" to ensure that force is applied in either direction.
- If you select multiple surfaces for a force, then Live Parts will apply the force proportionately across each of those surfaces based upon the surface areas. For example, if you select two surfaces for a force, and one has 3x the surface area of the other, then Live Parts will apply 3/4 of the force will be applied to the larger surface and 1/4 to the smaller one.
- You can select surfaces for a force that are adjacent to only a portion of a fill zone. For example, if you want to apply different forces to several regions of a shoe sole, you can create multiple surfaces (as reference geometries) representing contour lines on the sole and choose to apply different forces to each surface. During the Live Parts growth process, the cells in the fill zone (i.e. shoe sole) would feel different forces based on the surface to which they are adjacent.
