This Tech Tip shows some helpful shortcuts for selecting lots of geometry.
Selecting cut areas manually, either in operations directly or in Mill_Areas etc, is pretty easy when there aren't many surfaces.
But when you need to select several 100 surfaces or have features which you see again and again, the following will show you a few tricks on how to limit your clicks and make the cut area selection easier.
Using color selection of course requires that you have different colors on your part, reflecting either features or certain part areas.
The colors can come directly from the CAD team, or you can add them in the CAM process.
In the Specify Cut Area dialog, open the Filter Methods drop down list and choose More...
Click Type button and select Face, then click OK
If you know the Color ID number, input it in the ID field and press Enter on your keyboard.
If you do not know the Color ID number, you can click Inherit From Object and select one of the part surfaces with the color you want to have selected.
Click OK until you are back at the Cut Area dialog
Click Select All
Now your surfaces have all been selected!
Using face NAME selection requires that you have face names on your part, reflecting either features or certain part areas. The names can come directly from the CAD team, or you can add them in the CAM process.
In the Specify Cut Area dialog, input the name in the Name field
Press Enter on your keyboard
Now your surfaces have all been selected.
You can reduce the user clicks even further by creating macros that assist you during the cut area selection process. To have a fully automatic macro without user interaction, it requires that either your colors or names are identical every time. Meaning you need to decide on a standard for your parts/features. If you are not able to decide on a standard, you can create macros with user-interaction.
The user action could in that case either be:
