Not generate toolpath sphere, default creation by the button GUI

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Create Solid sphere
2. Add other operation ( surface )
3. Add new Milling operation ( Poket operation ) 

What is the expected output? What do you see instead?

Generate the toolpath for solid object sphere, but  the secondary windows 
warning with "Pocket operation - Sketch doesn't exist" after click the button 
G0.

I've run the option's into guide 
https://sites.google.com/site/heekscad/help/surface

What version of the product are you using? On what operating system?

The last version on svn repository at time ~17:15

Please provide any additional information below.

Thanks Eugenio.

You need to select a scketch in your pocket operation.

Please reopen if relevant.

I followed the example given in 
https://sites.google.com/site/heekscad/help/surface and at no point does it 
mention anything about a sketch. This is about milling a surface.

So maybe there is no bug, and the help page is at fault, but as things stand 
the OP is correct.

I have just discovered the answer, which is the page referenced above fails to 
mention one crucial step, that of creating a sketch above the area to be milled.

So the summary of what the page should show is:
1) create surface from solid
2) draw shape/sketch to designate are for milling
3) create pocket operation that employs the surface and sketch created in steps 
1 and 2
