Last manipulation
These sets of commands allows to manipulate shoe lasts and objects on them.
B_FlattenLast
Flatten the last and add its boundary to the document as a curve. Select a curve on the last to allow the command to cut and open the geometry. This utility simplifies the pattern engineers' workflow by flattening the last in a quick way.
B_ChangeLast
Moves some planar curves from a flatten last to another one. Taking the source flatten last curve and the destination one as input, the tool generates two meshes with the same topology for the source and target last curves respectively. It also creates some new curves on the target mesh matching the position of the original ones on the source mesh.
Parameters
- Precision: The level of accuracy you want for matching curves.
- CopyCurves: Input true if you want to keep the original curves.
B_GradeGeometry
This command allows you to generate a graded last from a given mesh, SubD, surface or Brep. Starting from a last, the user must select a line from the heel to the top point, as a reference for last length measurement. The last ball is then computed automatically. The initial size is chosen by approximation from the length, while a target size needs to be given so that the command can compute the appropriate scale and produce the new geometry. It is also possible to choose the target measurement directly, such as length and perimeter, to compute the scale. Other objects can also be scaled together with the last.
Parameters
- Size style: The preferred grading system, like UK, France or Mondo points.
- Current size: The actual size that needs to be considered. It is computed automatically as approximation of the length with the nearest size in the selected system, but the user is free to change it as they like, and all the grading table will be recomputed accordingly.
- Grade to: The target size.
- Max iterations: Maximum number of iterations performed by the algorithm to find the right scales along x and y axis in order to reach the target length and ball.
- Objects to scale: Pick objects to scale with the last.
- Target length: The target length of the last.
- Target ball length: The target ball length, or perimeter, of the last.
B_GradeMultiple
You may want to generate an entire set of graded lasts basing on a specific grading table. Utilize this command to either create a custom grading table or use an existing one.
The parameters in the override section of the window are essential for creating a new table.
Parameters
- Min size, Max size: Table extreme sizes
- Size increment: Numeric distance between one size and the next
- Length increment: The difference in length between two consecutive sizes
- Ball increment: The difference in ball width between two consecutive sizes.
Additionally, you can opt for a different sample size from the one automatically recognized from the last length. A new layer is generated for each graded object added to the document. The color of each layer corresponds to the relative size, as illustrated below.
