Problem- 3D contouring basics?

[cadcam]

Thanks Greg I do thank you for this thought. (I'm just trying to be minimal impact on your time.)I try to help when I can.I for sure try not to ask if I cant find a few min to help.
I sent you a PM.

Please review the start of the part you are working on.

Tried to make small for download.can change that later.Please turn on audio.

Jay,

I can't thank you enough for doing that. I don't think your solution for the surface was any simpler than the one I came up with but I learned so many other shortcuts that your time and effort paid off in more ways that you know.

I'm still on MC X. I don't seem to have the Flowline options that show in your dialogs. But I didn't know that I could window-select everything and just set the boundary to stop at. I was going around clicking each surface. I also saw a bunch of other things. I'm going to go back and watch it a few more times to pick up some of your techniques.

You also kick-started me with the 'create geometry' options from the imported solid. With any luck I'll get to those parts tonight. I'm stumped with a Haas lathe problem right now.

Thanks again!

So you know I would of not ruffed it this way in the shop for me.I use the rough pocket all the down in to the pocket to.
I also noticed on yours you never came down to the true surface to finish or was some of the finish missing.

Glad that helped jay.

No, I thought the second surface machining operation did 'finish' the upper surface. It didn't? I'll have to go back and look at that.

As I posted in the beginning though: The intent was to leave the pocket material in there so the walls would have support during roughing. After the surface was defined, I'd step the pockets down in increments. The walls weren't high tolerance but I was trying to treat them as if they were (learning / practice).

Here is the info from your file.Review picture of STL compare.
