1.6. View buttons

Using the view buttons below the 3D simulation screen, you can select what parts you want to see as well as cut into workpieces. Note that you can turn on and off parts as well as zoom, pan, rotate, and cut during the simulation.
To open the view panel, click on the button with the glasses.
On the left side of the panel, you can select what parts you want to see during and after the simulation. On the right side, you can choose the workpiece style. The styles get their look from the materials you have defined in the Inventory Browser. You will also find the simulation speed controller on the right side of the panel. Use it to control the speed of the simulation.
Note about machine limits: You can select to show the machine limits. They are defined in each machine file. If your CNC program tries to go outside these limits, the simulator will alarm.
Using the button with the knife icon, you can open the workpiece cutting panel. Use the sliders to cut the part from any side to see its interior.

Some important notes about solid part simulation and speed:
The solid part simulation uses a lot of memory and computer power. The performance will depend on your hardware. If the simulation moves too slow, use the fast forward button to speed it up. For the fastest simulation, check the Disable solid option in the view panel.
Your computer and/ or graphics card may just not be powerful enough for solid simulations. In that case, you might have to turn solid simulation off altogether by checking the Disable solid checkbox in the view panel. You will still be able to simulate tool paths and machine movements.
There is also a Solid buffer resolution setting under the Program tab in the Settings Editor. It can be set to low, medium, high, or other. If the simulation runs slowly, set the resolution to low. Vice versa, if you have a powerful computer (and/ or graphics card) that has no problems simulating complex solid parts, set the resolution to medium or high. If you select the last option in the list, "Other", you can enter your own value for the buffer resolution.
Solid simulation has some limitations: First, note that using non-flat milling tools will create a much more complex surface, hence using up more computing power. For faster solid simulations, use flat tip tools. Also, note that cutting can only be done from the tip of the tool all the way up in Z. That limitation will be obvious if you try to cut a slot in the side of a workpiece with a disk mill. The disk will act as if it was a flat end mill with the diameter of the disk. This is true as long as you have the 2.5D solid buffer selected in settings. If you use the more advanced (and hence slower) full 3D buffer, side cuts will be correctly shown. For more information, see: Settings
The buffer containing the solid part has a limited resolution. If you zoom in too much, the workpiece will look rough. This is a compromise we did not to slow down the simulation too much.
Also, note that if you set up more than one workpiece on the table, only the first one can be viewed as solid. Another compromise to not overload the computer.
