Select Hole in manufacture operation issue...

[jrTBEJE]

See screencast. 

imported sketch. extruded to a 3D body. Holes seem to be there. Go to manufacture and hole faces can't be selected even with a free trial of the hole finder feature....

I am new to manufacture. I am building a CNC (which i modelled in F360) and i am using GRBL as post. I am just trying to define, drill, face and 2D contour operations to cut out a single panel from some stock. I have defined my CNC machine and parameters etc, the stock, but i can't create a drill operation as it won't let me select holes.

Panel design attached as F3d archive.

i can't seem to insert screencast. when i do it gives me an HTML error and removes the screen cast.

That's because you don't actually have holes in your extruded file.. You will need to create circles and select points instead

is this because the sketch i imported from PDF had defined the holes as four separate arcs? Is it possible to connect the four arcs in the sketch and also define the exact centre point. Or do I just create a new circle on top of the existing arcs?

The centre point in the PDF was defined as a small "cross" but in F360 it won't select the centre of the cross when i try and select the dead centre of the circle.....

i created a simpler panel with one manually made hole, and i was able to generate .nc code for GRBL ok with it. so i just now need to know how to edit my design or sketches to define the holes properly i guess. this is so cool 🙂

The sketches aren't coming in as arcs, just line/spline segments. Click the Inspect button ("I" shortcut key) and select the hole or edge. If it was a circle, it would give you a radius value.

Thanks for the response. Then how to join the four line segments (which are quarter circles) into a full circle so they can then be selected as a circle and/or made into 'holes'? If i try to mill a 2d circlular operation, same thing, can't select circle face.....the segments seem to be joined with no gap between them....

Sorry i am a newbie but somehow i managed to design this CNC in fusion (from 2d plans i bought in PDF) and now I have physically built it (almost complete waiting for screws). It took a while because i was learning.....sometimes the simple things i can't figure out like to to select objects, but then the complex things of making the assembly i can 😉

Now as a learning exercise, I am trying to get the physical machine to make one of its panels.....i'm almost there I think.

Like this:
Turn all of your sketched "circles" into construction geometry. Select the entities and hit the "X" key. Then, sketch actual circles, using "3-point" as mentioned above. You then go back to edit your Extrude command, selecting those hole faces:

Oh, before I forget; nothing you sketched is "Constrained". Constraining a sketch is the bedrock, most important, never-to-be-skipped step in proper Fusion usage. Doing this prevents your model from doing funky things and ensures that everything is "where it should be". Constraints take the form of: Dimensions and actual constraints such as Horizontal/Vertical, Perpendicular, Parallel, etc.

[jrTBEJE]

ok. I think i understand this instruction. thanks.

[jrTBEJE]

OK. I will find a tutorial on how to constrain things. Thank you.

[seth.madore]

How's this for an "all in one" tutorial?

[jrTBEJE · Accepted solution]

Amazing. This is gold. So many thing I did not understand are clearly explained. Thanks so much for taking the time to do this.

Thanks to Seth i was able to define the manufacture operations to mill the holes, face 1mm off the top of the gantry plate and cut the piece out of the stock.

Thanks so much. I though I'd share the sped up screencast video and the file.

Here is the screen cast.
