what i have done for our lab is a grasshopper script. you choose you kerf from a menu (of measured tests) and then you can fine tune it with a slider if needed. it takes the value and offsets out all the outer curves and offsets in all inner curves. one click solution that can correct any drawing (which is drawn without kerf correction) with a single click. this simplifies drawing management and gives one click correction when matetials or cut parametres change :)

Frankly, that's the only video I was able to find about kerfing explanation... Thanks! What I miss... is howto video about Rhinoceros e2e process of designing a laser cut model... I have some experience in SketchUp, but it seems the process is slightly different. And exporting faces there requires an extra plugin and some amount of manual work.

If you didn’t worry about the kerf when you cut all of those sides you simply flip one over and it should have the opposite kurf angle on it as well and should fit perfectly together?

The box file doesn't seem to be there anymore. Dropbox says it's deleted :-(

[TechnologyForFunVideos]

Hi, great video, thanks. Did you do the video of the box with the twist locking mechanism? I can't find it on YouTube.

[dr.aneeshatimalhpche]

Cool, but what is the name of the program?

[alexcalandria]

Can’t wait to see the last you show 🤩🤩

[cryoglobe]

Hello; great video ... and clear to understand

But I am wondering ...
1 - how do you then design stuffs for others so they can laser cut it ? without the kerf consideration ?
2 - how to tackle the kerf with a design of someone else without redoing the design ?

The link for the Free Box File doesn't seem to work for me. It says that the item has been deleted.

great video! If I wanted to cover this with leather (to make a tiered jewellery box) do you think a finger joint is appropriate for the base? or is simply glueing the sides with no special joints sturdy enough (as it won't go undone due to the cover material)?

Thank you tomorrow going to try to make my first box. Thanks for the help and PDF file. Are not all the lines on the file suppose to be red are they not all cuts?
