The Tools Grasping Posture Catalog is only available with a product license. | |||||||
This catalog contains postures that are related with the use of several tools and equipments such as grasping, pushing and pulling objects. To reduce the number of posture adjustments, several variations of the same posture are available. Those postures are useful for both beginners and advanced users to save time to posture the manikin using tools. | |||||||
For some postures, angular limitations have been changed to obtain an optimal and realistic posture. For example, in order for the manikin to kneel with the buttock against the heels, angular limitations have been edited. In that case, postures were saved with the associated angular limitations in the catalog. | |||||||
Most of the postures have been created for a specific percentile (5th, 50th and 95th for man and woman) to avoid self or object collision. | |||||||
You have the Human Builder product open. | |||||||

For information on manikin attributes such as attach, constraints, and
offset, please see the following procedures in the Human Builder's
User Guide > User Tasks:

|||||||
It is important to avoid applying the posture and the constraint without
the offset. If only the constraint is applied, the absence of the offset
can create a different result from the one expected with the constraint
because of the link to it.
Modifying the offset position also modifies the relative position between the segment and the object on which the constraint has been created. For example, a Fix On constraint on the manikin that has a different offset from the one established during the creation of the constraint results in a different position between the object and the segment than the one expected. |
|||||||
For each tool posture, the right hand and left hand posture is available with the same characteristics. If the posture uses both hands or both arms, one posture is available for the two sides. This posture is in the right and left arm. | |||||||
It is important to apply the posture with the tools according to the posture and percentile (50 percentile man, 95 percentile man, and 5 percentile woman) to prevent an unadjusted grip or to avoid having the hand pass through the tool. | |||||||
When the user pastes the posture+attach+constraint+offset and tries to use the reach or the inverse kinematics function, you get a confirmation window: | |||||||
There is at least one active constraint on this kinematics chain. Do you want to delete this constraint? To delete the
constraint, click Yes. |
