How can I do lines in the middle of my fillet's?

daniel_mckenzie143

Hi guys, Im designing a cube which opens out into its 6 faces. I've filleted all the edges of my cube but I want to draw/have some lines on the vertex to show that it is a connection point between the faces. Any help with how to do that?

Or just design 1 panel and then Mirror and Rotate+ copy.

Hi Martin, thanks for the reply! Im semi-new to Onshape so I'm still learning. How do I split the filleted parts?

Hi Daniel,

typically, with models consisting of several identical elements, you would only design one element and then reuse that as often as required. A cube can, for example, be broken down into 6 pyramids, their tops meeting in the cube center. A pyramid then is but a square and four triangles. If you follow that approach, You'll have much less work, plus you get the 'lines' you want for free.

If I model but one cut-off pyramid, I get all the planes needed to split a cube into whatever elements I need, and to subsequentially rebuild it from those parts:

You could create intersection planes through the center at 45°. But once you have these, you could as well split the filleted parts, where they are meant to touch, so there will be lines. This is a nice example for the difference between CAD and illustration. Model your intent, and you get what you want. You'll need it later, anyway, when you work out how the locking mechanism works.
