When generating the G-Code of an operation or a group of operations, TopSolid checks that the approach is made from the tool change position.

If this is not the case, this message appears:

Two solutions are suggested in this message:

• Change the program type to " Per operation " in the program management (Operation > Programs management):

• Select all operations that use the tool for G-Code generation:

If you still want to force G-Code generation from a single operation without using the solution 1, this operation must come from the tool change point.

To do this, just modify the operation approach and insert a movement to this tool change position:

• Right-click on the operation > Link movements > "Edit inter-operation"

• In the pop-up window, switch to “Manual” mode to be able to change the movements between the previous operation and this operation:

• Click on "Add Change Tool"

A small red arrow appears to indicate manual modification of the approach:

WARNING: This function will create a direct movement to this position (X, Y and Z at the same time in our sample). Simulate and, if necessary, decompose these movements.

• Do the same on the next operation if you want to isolate an operation.

It is now possible to generate G-Code for this operation.
