help needed

I get the message in Report view: "File was not written with this version of the topology". Did you reuse some old file and trie to pimp it? If so please re-create it from scratch.

I get the message in Report view: "File was not written with this version of the topology".

I get that message very often, even with files I have just created and reopened. It indicates an error of some sort, but it never seems to cause any problems at all.

If you want to mill half cylinders you should model half cylinders.

If you can look onto it, I just create thing I would like to mill, but I have problem with cylindrical shape.

Hi efix,
to create a 3D pocket from a part wich is not a pocket, the part has to have a flat area at the bottom.

Hi, it works! (at least in part), after simulation I got steps, how to do that to be smooth? Thanks!

With a 3 axis mill, there will be allways some steps. Just make the stepdown size smaler and the steps getting smaler to...
With a big area on the ground (as i made) it's a lott of milling time then, but the "groundplate" need's not to be so big.

For a better 3D surface at all you need to run a 3D Pocket operation first and a 3D surfacing operation secound. But the D surfacimg dosn't work without installing OCL atm, which not is so easy at some Operating systems.

I create Facing Operation (no 3d surface on my version) and then I choose all rounded surfaces and generate mesh, but only what I've got after simulation was flat surface on top not over all rounded edges. Why? Because of that OLC?

Edit: What is OLC and where to get this?

Check the wiki, which has a lot of good info about configuring, and using Path-WorkBench:

Or the many forum posts regarding Open Cam Library (OCL)--for example...

Etc..........


In the wiki, make sure you look into enabling experimental features.

If you are using Linux, it will be more straightforward. If Windows, I had trouble compiling OCL, but then noticed in one of the threads that a compiled version is linked.

Thanks JoshM. I am on Windows. I try to follow https://github.com/aewallin/opencamlib/ ... er/Windows right now I am downloading visual studio to compile boost. I'll let know when I'll turn it on and it would start working.

Fastest way is just to use the pre-compiled version
