Tool Library Work Flow Update
In BobCAD-CAM V37, the tool creation workflow in the Tool Library has been significantly enhanced for user-friendliness. The create, delete, copy tools to library, and clone options have been moved to their own toolbar in the grid view of the tool library. Now, when a user clicks "Create Tool," the focus automatically scrolls to the new tool's location in the grid view, and the Tool Parameters flyout opens immediately for editing. This eliminates confusion for new users, who may not notice that a tool has been created, and saves time by removing the need to manually open Tool Parameters and scroll to the new tool's position. This update simplifies the process, making it more intuitive and efficient for users to create and manage tools.
Warning to Save Tool Library
In BobCAD-CAM V37, we've introduced a useful feature for those moments when you hit "x" instead of "OK" after modifying a tool in the library. First, we've replaced the 'x' button with a Maximize/Restore button to prevent accidental closure, but if you still manage to close without saving, a prompt will now appear: "Click Yes to save changes and close or click No to discard the changes," with Yes/No options. This ensures your changes are saved and spares you from redoing your work. You're welcome!
Tool Crib Improvements
Remove Unused Tools
A new button allows users to automatically remove all unused tools from the Tool Crib. Previously, this task required manual verification and deletion, which was tedious. With this new feature, a simple click is all that's needed to eliminate any and all unused tools. You can't get much easier than that!
Remember Tool Crib Size
BobCAD-CAM V37 now retains the previous window size and position of the tool crib, addressing a common issue for users with specific screen configurations. Previously, users had to resize the tool crib window each time it was opened, as the software did not remember the last used dimensions. This enhancement keeps it nice and convenient by keeping the tool crib window at the preferred size and position every time it is accessed.
Merge Options for Tool Crib Import
The new Merge Tool Crib option in BobCAD-CAM V37 makes tool management a breeze by letting you merge a saved tool crib with your current one. Before, importing a tool crib meant losing your existing setup, which was a hassle since you'd have to re-add your tools manually, risking mistakes. Now, you can easily combine your tool cribs, keeping everything you need in one place without the extra work.
Updated Tool Crib Selection
In BobCAD-CAM V37, we've addressed customer frustration with tool selection in the Tool Crib. Previously, if a tool wasn't dragged from the Tool Library section, up to the Tool Crib section, the software would continue to use the previously active tool in the Tool Crib. Now, when a tool in the Tool Library is the last item the user click on, a prompt will appear: "Last selected tool(s) were in the Tool Library. Would you like the tool(s) added to the Tool Crib? If multiple tools have been selected, the first selected tool will be applied to the operation."
*While the proper method is to move tools to the actual Tool Crib, this ensures users won't incorrectly assume they have done so.
Show Tool Count in Tool Tree
BobCAD-CAM V37 now features a new display in the Tool Tree's Info column, showing the number of tools used in the job next to the number of operations. This makes it easy to verify the tool count at a glance. In the past, users couldn't see the total tool count, which made verification more tedious. This enhancement provides a quick and efficient way to check the number of tools in use while reviewing operations.
Default to Last Used Machine
In BobCAD-CAM V37, the Current Settings dialog has been improved for better user-friendliness. Previously, launching this dialog from the "CAM Default" item or the CAM ribbon always defaulted to the BC_3x_Mill machine. Now, the software will use the machine from the last visited job, making it easier to edit or view parameters relevant to the current active job. If no item has been selected in the CAM tree, the machine from the first job in the tree will be used.
Machine Refresh Button
We're also adding a more intuitive way to refresh the machine being used for the job. Previously, when a machine was changed in the job users had to right-click on the Machine in the CAM Tree, select Edit, and click OK to refresh the machine being shown in simulation. Now, a "Refresh" button is added to the right-click menu, allowing users to update machine changes in the current job a little quicker. Additionally, when changes are made in the CAM Defaults > Current Settings, a prompt will appear asking, "Do you want to apply these machine changes to your current job?" Clicking "Yes" will automatically refresh the current job's machine settings.
Save Use Automatic Tool Numbering to Job Template
A new enhancement allows the Use Automatic Tool Numbering checkbox to be stored in Job Templates. Previously, this option was always checked by default, even if it was unchecked when the template was saved. This required users to manually adjust the tool number before posting the code. With this update, the checkbox state will be saved in the Job Template, allowing it to be disabled by default when loading new templates, streamlining the workflow and reducing the need for manual adjustments.
Remove Highlight from Geometry
The "Remove Highlight from Geometry" update in BobCAD-CAM V37 enhances the way feature geometry is highlighted. Previously, when you clicked on a feature in the CAM Tree, the corresponding geometry would highlight in the graphics area, helping you identify specific features among many. However, the highlight would remain until another feature was selected or the Job was clicked in the CAM Tree, which could be inconvenient. With this update, you can now remove the highlight simply by clicking anywhere, including empty space in the graphics area, making the workflow smoother and less distracting.
