# Cutting specific angles

how can i set lightburn to cut specific angles using my ortur laser?

Can you be more specific?
If you draw a line you can place it at any angle you wantâ€¦

thanks for the reply. i want to draw an angle of 5 degrees in say a triangle and then make a circular array of 48, so that i have 48 triangles in a circle with 48 by 2.5 degree spaces between.

that would be an isosceles triangle

â€¦something like that?

hi. exactly like that. thanks how do you do that so that the angle at the point of the isosceles triangle is say 5 degrees

Itâ€™s easy in LightBurn
Draw a line with the length of your 2 equal triangle sides, set it to 2.5 degrees in the angle function, duplicate and mirror this line and assemble it into a triangle.
Then draw a small circle, put the tip of the triangle in the center of the circle and use array function.

â€¦was that understandable?, just let me know if I need to explain myself better.

thank you. i am new to this. i didnâ€™t know there was an angle command. can you explain how to navigate to that and hot to use. thanks for your help.

Making the â€ścircular arrayâ€ť this way was unknown to me.

I would have done the triangle and the â€śarrayâ€ť differently, perhaps a little faster, but with this way of doing the â€śarrayâ€ť it definitely becomes faster.

I canâ€™t make a video but I can try to explain if you think itâ€™s necessary.

Of course we would like to hear/see other options. It was only the first idea I got and didnâ€™t think much about alternatives, come and show us other options.

Basically it is taking advantage of the functionality of the â€śRectangular Polygonâ€ť tool. (Which I learned here on the forum)
I will try to illustrate through screenshots how I reached the same goal.

I started by selecting the â€śRectangular Polygonâ€ť tool

Draw the polygon, opened the properties window

and put the values I wanted in width, height and put 3 in the number of sides. This changes the 6-sided polygon to a triangle with the width and height specified in the previous fields.

Then it was basically following the example given by @bernd.dk to make the â€śArrayâ€ť.
Draw a circle as a frame and centre it on the vertex of the triangle.

and I made the â€śArrayâ€ť selecting the number of copies that I liked.

Basically in 4 to 5 stepsâ€¦
If it helps someone, even for other polygons, thatâ€™s whatâ€™s important.

P. S. On my monitor the vertical lines appear staggered instead of straight, but this is because my monitor has low resolution. As I took a screenshot of the image, I donâ€™t know how it will appear here.

I havenâ€™t thought along these lines at all, thanks for that.

Youâ€™re welcome!
I also wouldnâ€™t remember this before knowing the features of the â€śrectangle polygonâ€ť tool. Now I use it whenever I can.

Thanks guys for your help with this. I am sure i will be back with more questions before too long. Thanks again.
