With this feature, is possible use the 3D model rappresentation to detect machined area by previous operations and trim the toolpath , in order to avoid empty area.
2) Now i want to add a second contouring operation , the circle is the geometry for the second operation.
You can observe the toolpath is not optimal , the tool is working on a empty area.
option a) For simple case , you can reselect the geometry used in first operation and setting it as stock .
See images. Set ON this icon to show all hided geometries.
Select the geometries and set them as [STOCK PROFILE] .
option b) Click on [Trim toolpath by current stock section] .
A planar section of the stock model will be created , and the profiles generated from this section they will be used as stock profile.
This option is more easy to use but it's more computationally expensive.
As final result , you can see the toolpath is trimmed , skipping all useless movement in the already machined area.
