Reply with QuoteUpload the file, if it is a .STP file then anyone should be able to open/ check it.
Sure it isn`t a .STL file? A lot of 3D scans are save as a native .STL file which is usually the format for 3D printers.

Machining a STP file in Bobcad Ver30 build 2553. Not happening?
I have a 3D scan of a Skull and it has been saved as a stl file, I can import it move it around select it ect.ect. when I go to machine it I cant select it.

Re: Machining a STl file in Bobcad Ver30 build 2553. Not happening?
My bad, it is an stl file. will that make a difference in machining or selecting it?Originally Posted by The Engine Guy

Re: Machining a STl file in Bobcad Ver30 build 2553. Not happening?
I had to pay for the file I would upload it but that would be disrespectful to the guy trying to make a living selling the files...

Re: Machining a STl file in Bobcad Ver30 build 2553. Not happening?
Yes, big difference, you can`t use an STL file for Cad-CAM software to create toolpaths from, as you paid for it then you will need to ask the seller to re-send you the file in either .STP or .IGES formats, those you can manipulate and toolpath from in Cad-CAM softwares such as BC

Re: Machining a STP file in Bobcad Ver30 build 2553. Not happening?
Well thank you very much. I've been seeing exactly what U can do with this teaser file, I'm using a solid to only expose a layer at a time, like a slice eng does for printer files, each layer I'll outline the new exposed surface move the block down .020 and repeat the process, Is there any simpler a way...?? I really want to get that into a workable file

Re: Machining a STP file in Bobcad Ver30 build 2553. Not happening?
You can use STL for toolpaths.... Not sure why you cant select it... Lets look at a couple things...
How Large is the STL in MB?
Can you point me to the model you bought?
Do you have any other versions of BobCad?
You should be able to select it for "3d toolpaths". It wont be available to 2d operations. So what exactly are you trying to do with it? Can you describe a little about your file?
Re: Machining a STl file in Bobcad Ver30 build 2553. Not happening?
Didn't see your last post until after....
Looks like you may be trying to "Slice layers" or actually generate 2d profiles at an arrayed depth?
You may be able to get this done with something like a zlevel finish op....
Can you post some screenshots?
Re: Machining a STP file in Bobcad Ver30 build 2553. Not happening?
Done from .STL file
Re: Machining a STP file in Bobcad Ver30 build 2553. Not happening?
Well lets see, the file is 32 mb in size, It was bought off a 3d model site, I'm not sure which one it wasn't very expensive. Its various profiles and renders are going on a custom build, motorcycle.. It selects as a solid until the machining operation is selected,. It wont select at all until multiaxis is selected then it selects and computes with an error of no drive surface selected or a variant of that statement. "Drive surface not selected" ... Its been saved as a bobcad file with no change in how it behaves in the software.

Re: Machining a STP file in Bobcad Ver30 build 2553. Not happening?
other versions of bobcad, I think I started with ver 22 or something like that. I still have them but only V29 with 4th axis still up and running and this ver of 30 with multi axis.... I have found a few sites with file formats for cad software but the resolution is lacking in the models I've looked at with a reasonable price behind it... The higher the res the more it cost... Almost makes you want to build your own 3d high res scanner....

Re: Machining a STl file in Bobcad Ver30 build 2553. Not happening?
I was going to build the 2d geometry then quarter it on opposing planes and surfaces the sections of geo layer by layer .... Its easier to find a file already built and manipulate it into what i, going to need ... I was just seeing what I would have to do to use the model I already bought and found its to labor intensive for me...

Re: Machining a STl file in Bobcad Ver30 build 2553. Not happening?
You wont be able to use STL for 2d work. Or extract any edges or "Clipping plane profiles" and such, with BobCad...
But you can generate "Layered toolpaths" with the 3d ops, etc....
But there is just too little info here to really help much. If you are moving with different models, then good luck and let us know...
Re: Machining a STl file in Bobcad Ver30 build 2553. Not happening?
this is the stl file, I can not machine this stl file layered or what ever using 3d machining or multiaxis, its not working on this file... JRMach just posted something he made from an stl file but no elaboration on how or what? I don't know what he is saying ?? Anyhow I'm going to have to do it the old fashion way it looks like ...

Do you want elaboration ? We can go into detail if you like

" I'm going to have to do it the old fashion way it looks like ..."
that's not so bad at all,that makes it art and special
Done the custom motorcycle thing for 8 years in a different life
Anyhow,be glad to share the skull experience,however,,that was done many years ago,,I am sure with the new versions of BoB that this would be even easier and better
Check out this gawd awful creature that some day I may make,,wonder where I got him ???
Re: Machining a STl file in Bobcad Ver30 build 2553. Not happening?
I would like to know if some STL files are selectable in the cam portion of Bobcam and some are not, what sets them apart ? This STL file is one of those that will not. You saying you have machined STL files with bobcad? I assume anyway. There must be something I'm missing...

Re: Machining a STP file in Bobcad Ver30 build 2553. Not happening?
Here is the file I used to make papa and baby skully.
This was free on the internet,hence I have no problem sharing
See if that works somewhat,,,then if needed we can get into how I did this with only a 3 axis machine,,,,(4 axis would be better) a little ingenuity and planning and is possible with 3 axis
Stl's are usable. But not for some ops.
Like 2d operations. I think some of the multi axis stuff will require NURBS surfaces also. Like "morph between curves" etc....
Without the info of what you are trying to do, its like guess work...
If you can get specific, help is there...
Re: Machining a STl file in Bobcad Ver30 build 2553. Not happening?
Freecad can be used to convert .stl to a solid by importing the .stl in the mesh workspace then in the part workspace create shape from mesh then saving out in the format of your choice,
