Parts section¶

The Parts section is where you can manage all the pieces you want to nest and it consists of two separate views:

• a tree outline where all pieces are grouped by their assigned material - so you can quickly spot all parts having a certain material; parts that haven't been assigned a material yet are grouped under the default <Unassigned> group;
• a grid view where all pieces are shown with their assigned properties

Model outline¶

On the model outline the user can:

• quickly select a part on the parts grid by double clicking on its name
• rename or delete a part by right-clicking on its name
• add multiple parts to a material group by right-clicking on a group name; by doing so, all added part will be assigned the corresponding material

Parts grid¶

The parts grid shows a preview of the parts and their assigned properties. In detail, the displayed columns are:

• an image preview of the part/piece; by hovering the mouse over the image, a bigger preview is shown
• Name (editable)
• Part gap (editable), which represents the minimum distance that needs to be maintained among all placed pieces in the nesting phase
• waste (%) (editable), which can be set to add a manual additional waste to the nested result
• Rotation factor (editable) lets the user specify the rotation angle step to consider during the nesting phase (for example, setting a 30 degrees rotation factor implies that the nester will attempt to place the part rotating it by all the multiples of 30, that is [0, 30, 60, 90, 120, 150, 180, 210, 240, 270, 300, 330 degrees] if the initial rotation is zero); the lower the rotation factor, the longer the nesting phase, because the nester will have to try placing the part rotated by way more angle values
• Initial rotation (editable) is the part's base rotation considered by the nester
• Quantity per pair (editable) represents the number of part copies considered in the computation of the final yield value
• Use mirrored piece tells the nester to use both the original piece and a mirrored version when placing part copies on the nesting material sheet
• Allowed materials shows a material picker dialog when clicked. The dialog lets the user select a material from the material list or remove the current assigned one
• Prime can be set to assign the piece a higher quality

Minimum box rotation¶

On the top-right of the parts grid, you can find a button to quickly set the minimum box rotation for all parts.

The minimum box rotation is defined as the rotation that minimizes the area of the part's enclosing rectangle.

This usually guarantees better nesting results, especially for the Interlocking Mode nesting (see Interlocking)

Inspect part¶

A single part can be inspected and its initial rotation can be edited by double clicking on its preview image.

The Inspect part dialog shows a larger preview of the piece and the user can perform the following operations:

• aligning the piece along a given axis, which can be traced by clicking two points on the drawing area; the piece will be rotated so that the traced axis lies horizontally on the bottom
• measure distances on the piece. First of all the user needs to click on the align button to switch from "align mode" to "measure mode": the icon will change and a combo box where to choose a unit of measure appears; by clicking two points on the drawing the measure of the distance is captured and copied to the clipboard (converted to the selected unit of measure)
• minimize the piece's bounding box, by clicking the related button; the piece will be rotated so that its enclosing bounding box is the smallest possible
• rotate by 90°, by clicking the related button; the piece will rotate by 90° at each click, cycling through 90, 180, 270, 360 angles
• specify a rotation angle in alternate ways:
  • filling in a given angle in the spinner control
  • using the slider
  • using the mouse wheel over the drawing

When the user confirms the dialog, the rotation is applied to the piece.

Advanced part editing¶

Some other UI shortcuts are available to edit parts in a convenient way:

• you can select more than one part/row in the grid by clicking on the rows' first cells while holding down the SHIFT key.
• you can change a property value for multiple parts in one go by right-clicking on a property column header and clicking on Edit selected.. to apply the change to all selected parts, or Edit all... to change the property value for all parts in the list
• you can also right-click on a row's first cell to perform one of the following actions:
  • set second cut: you can select one of the other parts to be used as a second cut for the current selected one
  • remove a second cut: if the part was previously assigned a second cut, you can remove it with this action
  • duplicate the selected part: a part with the same properties will be added to the list; the new part's name will be added a suffix (like (1), (2), etc)
  • copy parameters to copy the properties of the selected part
  • paste parameters to apply the properties previously copied to another part
  • explode part sizes to consider all sizes associated to a part as if they were independent parts; by doing so, all sized copies of the piece are moved from the size list to the parts list
  • delete the selected part

Import a part¶

You can import parts in several ways:

• You can import one or more parts by clicking the Import shape... button above the Parts grid. The supported file formats are *.svg and *.dxf.

A dialog with a preview of the parts being imported will show up: in this dialog you can choose which parts to actually import and - if any part contains another shape or outline - they can be optionally imported as second cuts.

Second cuts can be also set up later in the Parts grid. * Alternatively, click on the Import files button on the top menu bar, and select a *.jcp file (Jevero Cost Part file), previously saved with Jevero Cost. All the pieces contained in it will be added preserving the existing part list * You can also open a previously saved project (*.jcp), by clicking on the Open... icon in the top menu bar. The difference from the above mode is that the previous project is completely discarded and another one is created with the new parts.

Leather / Strip assessment¶

Parts having a leather material are not nested in the same way of parts having other materials. Their yield is computed with a different algorithm, where 6 copies of one part are placed using the "enclosing parallelogram" rule.

The 6 copies can be placed without any rotation (0 degree mode) or with 2 parts rotated by 180° (180 degree mode). The result of applying these different methods are shown on dialog that can be opened by clicking the Leather assessment button, above the Parts grid.
