How to create notch and marking along the bending direction at the bend line?

[tkddud711]

ilogic : How to create notch and marking along the bending direction at the bend line?

Hi?

I would like to generate notch and marking lines on the bending line in ilogic.

As with the attached file, the bending direction is marked at the upper side and the bending direction is at the lower side
I want to give a notch.

If it is not what I want, I would create a hole 10mm away from the end of the fold line when the bending direction is upward, and create a hole at the end of the fold line when the bending direction is downward.

Help!

@tkddud711,

Can you please provide manual steps to accomplish the same task? Is there any specific way to identify to direction of bend line?

Thanks and regards,

@tkddud711,

Can you please create sample notch manually and attach part file? please make sure that files are non confidential.

Thanks and regards,

Below sample VBA code can be used to cut definition in a sheet metal .
