Split into Connected Fragments
If you right-click on a fragment and choose Split into connected fragments, all selected fragments are split apart, so that only connected grid cells belong to the same fragment. If a fragment consists of two components, for example, and these two regions are not connected, they will both become individual fragments.
Select Grid Cells
Click the Select Grid Cells icon
to select individual grid cells. Selected grid cells appear blue. Click the grid cell again to remove it from the selection. You can select grid cells from different fragments.
Edit Grid Cells
After selecting grid cells, right-click anywhere on the screen to edit the selected cells.
- Reset Selection: Deselect all grid cells.
- Split off Selected Grid Cells: Create a fragment with the selected cells.
- Move Selected Grid Cells to: Select from a list of fragments to add the selected grid cells too.
- Remove Selected Grid Cells: Delete the selected grid cells.
Merge Fragments
To unify fragments, simply select all fragments you want to merge, right-click on one of them and choose Merge. The fragments are combined into one fragment. It is possible to merge fragments in any position, even if they are not connected.
Groups
Fragments of a part are listed in the volume data directory in the project tree. To arrange fragments in the project tree, you can create subgroups. To do so, right-click on the volume data and choose Create New Sub Group in the context menu. This subgroup is a subordinate directory of the volume data directory.
Click and drag a fragment into a subgroup or volume in the project tree to move it to the subgroup or volume. You can also drag whole subgroups into volume groups. Fragments or subgroups cannot be moved into other volume data sets.
If you move a fragment into a volume group, the structure cell you have assigned to this group is automatically inserted into the grid cells of the fragment.
The subgroups can be very helpful if you have a long list of fragments and you want groups of fragments listed together. You can remove groups only when they are empty. To do so, right-click the group and choose Remove Empty Groups.
Right-click a group and choose Rename Volume Group, enter the new name, and click OK to rename a group.
Delete Fragments
Right-click a fragment in the project tree and choose Delete Selected Fragments to remove the selection.
After you have removed a fragment, the grid cells previously occupied by that fragment are empty. This means that you cannot assign a structure cell to this area of the part nor produce it solidly. When you create a slice out of the structure, which subsequently will be prepared for production, the section of the deleted fragment will be empty.
Reset Fragmentation
Right-click the fragment and choose Reset Fragmentation to delete the fragments of the volume data. You can rasterize the part again to get a basic fragment and start new fragmentation operations.
Enlarge Grid
- Right-click the volume data (or any of its contents) in the project tree.
- Choose Enlarge Grid.
- Enter the expansion along the +/- X, +/- Y, and +/- Z directions.
- Click Expand Grid.
The Enlarge Grid dialog also displays the current cell size and the current outbox. The outbox specifies the position of the part in your Netfabb platform.
This function is only needed, if you want to have a structure bigger than the part. For example, it can make sense to enlarge the grid in minus Z to insert a support structure below the part.
