Parametrically space sketch for a desired width

tim.lavelle — Mon, 03 Jun 2024 10:20:30 GMT

Hi all,

I'm working on a cabinet/hutch design for my home office and am trying to ensure all my sketches are parametric, so that if I end-up changing a dimension, everything auto adjusts. I believe I am doing well so far, but am stuck on a workflow that I can't wrap my head around how to properly contain this so I don't have to set a manual dimension.

Below is a screenshot of the section I am working on:

The Orange line is the distance I want to split in half so I can place the Red rectangle exactly 232mm on each side. The 18mm board thickness is a Parameter I've defined amongst many others, but I can't find the appropriate way to split the distance from the board on the left, to the board on the right edge Orange line.

I am sure there are more details you would want to help deduce a solution and I'm happy to help answer. While I am looking for a solution, I'm not looking for someone to outright point out how, but if there is a keyword, or sketch constraint which could help me do this, I am more than happy to read up and understand it better.

As always, thanks for the help and I hope this makes sense!!

Well there are as always a few ways, Symmetry, equations. but I tend to use construction lines.

Put the equal constraint on the construction lines and the gaps will always be the same. You may also need a horizontal/vertical constraint or two depending on how free the centre rectangle is.

Make the body on the left end.

Rectangular Pattern that body, count 2, Extent 250mm.

(New body will be halfway when calculating the centres spacing of each board.)

Might help....

Thanks @carl.j.barker and @davebYYPCU!

Both options worked a treat! The equal constraint is great, going to use that in a few other sketches now as well.
