Make multiple components/bodies conform to one body?

[agdericco]

Hi, I have just finished a large elaborate furniture design that surrounds a bed. All aspects of the design rely on the dimensions of the bed and I just realized that I am off by an inch. Is there any way to make every individual body or component in the design conform to one body or will I have to go through everything manually? I appreciate the help, thanks!

Hi,

the simplest and most comfortable solution is to use variables in the parameter list.

If you can share the design  (export as .f3d, or use web interface to export as .f3z and attach to next post) we might be able to provide more specific feedback.

Thanks for the advice, I have attached my design. To be more specific the mattress should be 75 inches long and I had designed it as 74. Thanks again.

Theoretically there is a way to this completely parametric. You would basically just have to modify that dimension in one sketch and all other geometry would automatically re-compute and adapt. That is how I would structure this design.

However, that requires that you have a firm grasp on how to model with a parametric CAD software.

In practical terms, unfortunately your modeling workflow violates so many best practices that you'll have to adjust things manually.

There is a strong change that even that isn't not going to be successful, because your design has a good number of yellow and red icons in the timeline indicating warnings an errors.

Those need to be fixed before you continue making any other changes to this model.

Correction!

You'll only have that many errors and warnings in the timeline if you adjust the 74" dimension in Sketch 1 to 75".

If you don't you'll only have 4. Of course if you do make that change you'll still have to deal with teh errors and warnings listed in my last post.

Hmmm I see, thank you for your advice and I appreciate you viewing my design. This is my first experience with Fusion 360 or any CAD program and I should have taken the time to learn properly before diving in. If I have to make manual adjustments then so be it. Thanks again!

Your 4th operation is a Move.

As a beginner at any time you are tempted to use Move, you should STOP and ask questions here.  Move is (almost) always used incorrectly.

Your 5th operation Extrude3 is what I call the "wack and hack" technique of modeling.

It would have been more efficient to do Extrude2 with an Offset and this eliminates the Move and then simply edit the extrusion distance rather than "hacking" away excess material.

All of this comes with experience.

You did a good job of fully defining MOST of your sketches, but that should be ALL of your sketches.

I prefer to model with symmetry about the origin as that generally saves work.

And forget you ever saw Move...

Thanks for the advice! I believe I will take the time to watch some tutorials and get a better grasp of Fusion 360 and then reattempt this project. Thanks again!
