Creating geometric designs in Carbide Create

[WillAdams (William Adams (Carbide 3D))]

as requested on support…

given the design:

4.5mm wide both sides…

I believe that’s 4.5M(eters)

Its for ceiling and have a through cut
We have 3600/1200 bed size of CNC and we want to design this accordingly after >cutting it should be a big circle
Normally we use 3600/1200 sheet size
And its Jali size is 25mm

Start by launching Carbide Create:

then choosing “Job Setup”

Ok

Set Background

Load Image

and adjust the scaling and positioning:

Done

Note that it will be easier to be able to see the center:

OK

and for the Grid to pass through that point

Ok

then, it’s simply a matter of drawing some circles:

and adjusting their size:

Then, one must determine the arc used by drawing a circle, and adjusting its scaling and position until it lines up:

Zoom in:

It’s not quite as symmetrical as I’d expect, so we count the instances of one quarter of the design…

Note that we need to know:

• interior spacing for a given pair of circles
• spacing between the pair of circles
• how much each set of circles is rotated

If the first two are done using measurements, then the latter can be done by counting and dividing by degrees.

The design should enter the top/right of the inner circle centered at that dimension.

Adjusting things a bit we get:

with a final adjustment that we put the Midpoint of the original circle at a grid position:

ensuring that it is aligned with things consistently.

Then, we use Circular Array:

and adjust for center placement:

and then set the number of elements:

which then simply need to have extraneous elements removed and those which one wishes to keep, preserved, then joined together, which would be done using Trim Vectors.

Alternately, one can export to an SVG, do this in a drawing tool which groks compound objects:

and then reimport:

Super interesting. It never accrued to me to use the circular array tool for geometric design. That will open up a new door for me.

Moreover, with a bit of patience, as noted above, it should be possible to complete this sort of thing using only Carbide Create:
