Rectangular Pattern

im2U3FR — Mon, 01 Jan 2024 21:52:37 GMT

I am having an issue with doing an arc array. I have a simple square box, with a diagonal line going thru the center and a parralell line offsetting the center line. I did a three point arc using the two parrallel lines. So in effect a diagonal arc. The problem arises when I try to do a rectangular pattern for the arc. I only have the option of going vertical or horizontal, so that creates an uneven array pattern. how can I get a diagonal ability for the arc to create parrallel equal arcs. Thank you

Can you share your Fusion 360 file?

Your file attachment did not make it to your post. You cannot attach files using email replies, you have to attach them to a forum post

I do not know how many or what distance you want between these arcs but you need to use the sketch Offset command. Please keep in mind you must offset the original each time incrementing the offset amount. You cannot offset an offset curve.

Model is attached.

While it worked perfectly, I am have issues with trimming the excess arcs from the outside of both boxes trimed to the edges of the inner box. See attached.

@im2U3FR

There is no need to trim them.

If your true Design Intent is not something like the Attached file - then more information is needed.

Bottom line - it is seldom necessary to trim sketches in Fusion 360.

@im2U3FR

...and another example...

Whenever possible - you should provide an image or link to an image of something similar to your design that already exists in the real world. That would eliminate a lot of guesswork.

Thanks see attached. It's cut out on both side in opposite directions.
