How to create a polygon to form a final object shape?

[Homoud]

Hello,

I am unable to cut a stroked edge (thickness) without affecting the overall object shape (changing the stroke size will impact the overall shape so it should be constant in order to keep the edge curve same). Attached example for your support, please.

Thanks a lot.

you can set the stroke to inner stroke. Then it will not impact the outer edge. By default, all strokes are centred, 1/2 to inside, 1/2 to outside.

Is that ok for you ?

Example the first triangle is 6pt and the second is 3pt…

 

The only thing I switched is the way the thickness is applied :

Basically I would follow @NotMyFault's advice here.

But since you said ...

... I don't know if you meant to cut (subtract) one triangle from the other one here (?).

However, in case of a geom subtract of two triangles is meant, you have to subtract filled triangles and not just stroked (none filled) ones. To get filled triangles with round edges, let's say the red one, use the Corner Tool (select all triangle nodes and apply some wanted radius), then place a slightly smaller (same edge rounded and centered) filled white one on top. Select both filled rounded triangles and perform the subtract (you said cut is subtract meant?).

The problem is that if I do the mentioned ways, the interacting third object will not be inline. 
 

I used the second triangle to resolve this challenge but failed to create the ultimate shape for utilization.

Basically I needed a no-color triangle with a 3 pt. Stroke ROUND EDGE but with 2 pt. Stroke Thickness.

Please help!

Like this?

However, note that the Erase blend mode will rasterize anything below.

Or rather like this?

However, note that the Corner tool corners are not scalable: when you resize the triangle, the corners will remain at 3 pt radius. (Sometimes that's a "good thing", other times that's a "bad thing"…)
