Hatch Pattern Direction by Object, not by View

[Thomas36 (Thomas)]

Hello,

I’m running a trial version of Rhino 8.

I’d like to use a simplified plywood hatch for the back panel of the box below.

How would I go about setting the section style by object, but have the direction or rotation of the hatch follow the long edge of the object through different section cut views?

Is there a strategy I’m missing, or maybe a work-around?

You can achieve it with Custom Section Style,

Hi Jessesn,

I should have explained in more detail.

The second image I posted shows two clipping drawings, a plan (top view) section and a side (right view) section. The hatching you see in the drawings is actually the same back panel from different views. The hatch is applied to the panel in the object properties section style dialogue, as you show in your video.

As you can see the hatch line direction simply remains horizontal across the two views. My goal is to have the hatch lines show as consistent along the long edge of the object in both views. So in the top view the hatch on the back panel would appear horizontal, and in the right view the hatch on the same back panel would appear vertical, following the long edge. Similar to how it would display if I modelled an actual sheet of plywood.

I’d like to keep the drawings dynamic, but maybe I would have to explode the clipped drawing and rotate the hatch pattern direction in the right side-section view? I was hoping there was a better way.

I’d like to know if this is what you want?

On the left I’ve modelled the geometry of an actual sheet of plywood consisting of laminated thin layers of wood.

On the right is a representation of a sheet of plywood with hatch applied to convey or simulate the lamination of the thin layers of wood.

Note the direction of the hatch in the Y-axis Section of the representation sheet on the right. It’s rotation is incorrect.

I would like an accurate representation of the lamination in all section cut views, (x, y, and z) without having to model the thin layers of an actual sheet of plywood.

I think you can achieve it with Section Style By Clipping Plane, and for your reference.

That only works for a single object.

It’s okay, I’ll have to resort to hatching some 2D surfaces in the layout to cover the section cuts that are incorrect.

Thanks for your time.

For objects like this, you can use Section Style = Custom to achieve the desired result.

I just broke up with Trimble.

Thank you, sir!
