Scaling and Maintain offset

[Anonymous]

Hello everyone,

I'm very new to Fusion 360, i've been watching a number of YouTube videos but I've not been able to find the answer to my question.

I want to scale a design but maintain the .45mm off set i have regardless of the scalling size.

Sorry this has been asked, i've tried looking but have not found the answer.

The file is attached.

So with this file the snowflake extrusions patten has a width of 0.45mm, as soon as you scale it up or down these measurements also change. I understand why this happens, but is there a way to maintain this at 0.45 mm rehardless?

Thanks is advance.

YES

1.  Scale the body

2. create a sketch > project the scaled body into (uncheck Projection Link > blue lines)

HIDE Bodies in Browser

3. delete outer profiles

4. create new offsets (0,45)

Thanks for the information,

The only items I don't understand is  project the scaled body into (uncheck Projection Link > blue lines, could i get some more detail or a link to a video to save you typing.

Sorry like i said i'm new 😞

@g-andresen has given you a great solution but since he is off-line I thought I would explain the step you are wondering about.  In the Screencast I take the process up through this step and a little beyond.  He says to erase the outside projected edges, I think it is easier to project just the inside edges.  With my method you have to be very careful to not get small breaks such as the one shown below.  If you do, you have to go back and project the missing edges.  His method will avoid this problem but I think erasing all the outside edges is a worse headache.  You be the judge.

I changed my mind, use @g-andresen suggestion.  Project the entire top surface and erase the outside edges, then offset.  There is too much danger is getting an open profile with my first method.  By the way, the Screencast has some goofs in it.  The reason I could not get the offset to pickup the entire edge is because of the projected sketch had breaks in it all because of my method.

@g-andresen  and @jhackney1972 , thanks for taking the time to help me, these have both worked.

There is another way without all that sketch manipulation.  I found that your SVG has duplicate outlines, (causing errors,) and was not symmetric, so used Native Fusion sketches.

Run up the timeline.  Pics will not embed these days.

Edit Scale Feature to change sizes.

Darn Clever Dave!  I love to see other solutions and this one really takes the "tediousness" out of creating the desired outcome.
