Help with Carbide Create Pro

[erica (Eric Ahrens)]

I just got the trial version of CCPro and have a question.

I have a cube about 3 1/2" square and 1 1/2" thick.

I want to put a 30 degree angle from all four sides of the top perimeter down to 1/2" from the bottom. Can CCPro do this?

Yes, but what material are you cutting?

Using what tooling?

Have you sourced long-reach tooling?

Two ways to go about this:

• draw it up in a 3D CAD program
• model directly in Carbide Create Pro

We’ll do both here, and use the twain to verify.

First is a 3D CAD — a free/opensource/online option is BlockSCAD:

The base is quite simple:

and making the same thing in Carbide Create is likewise quick/simple:

Next we need to draw things up in profile:

and then work up the angled line:

Draw two lines:

and join them:

Yes

Then rotate 30 degrees:

Done

copy-paste

then drag into alignment:

Then select the other:

and mirror it:

Select the geometries:

and use the Trim Vectors tool to remove what is not wanted:

OK

OK

If desired, use Join Vectors.

The necessary point is to get the side of the square:

so we make a square of that dimension:

and knowing this dimension we can finish making the 3D model:

which just requires changing the bounding operation from Union to Hull:

which may then be exported as an STL:

angled block.stl (1.1 KB)

which may be imported to make the 3D Model:

To make the equivalent in Carbide Create Pro requires drawing in some more geometry:

Model this to the thickness of the base:

Then draw in additional geometry for the angles:

Rotate the geometry 90 degrees:

Apply

Done

Select the inner square:

and fill in the interior:

Apply

Subtract the base:

Wow, that may take me awhile to digest. Thx. I am working with wood and have a couple of long bits.

Thanks for the advice and pictures
