Hatching

simon le bon

As you probably know, there is no Hatching Tool in SketchUp.

hatching a complex shape by hand can quickly become a tedious task

TIG's 2D Tools includes a Hatching Tool which works with tileable textures.

Tig's 2D Hatching Tool picture:

But if we need/want hatches made with real lines, here is "my" method: (as usual many ways are surely possible and may be more simple than mine ??)

Tools used:
Jim's Construction Line Tool
Didier Bur's Projection Tools v2
Chris Fullmer's Select Outer Edges v1.0
thomthom - Selection Toys

The principle is to use intersection with the model between a shape and a grouped shape (this way that only the shape is going to inherit the intersection lines). The point is that using a flat range of edges as the group doesn't lead to intersect anything. But if these lines are dressed as vertical rectangles, the intersection gives the desired result...

As usual, great stuff. This would fun in combination with Joint PushPull.
Do you think there would be a way to turn these into a texture that can be tiled?

Dear Dale,

Thank you for encouragement,

Heu! I don't see what combination you see to do with "Joint Push Pull"

Would it be possible that you were making the confusion between the image of Tig's 2Dtools_Hatching Tool and my tutorial itself?

Hi Simon
Ignore the above post, I was sleep deprived when I made it.

Hi Guys,

I have to apology after you because my tut is wrong.

I have kindly received a PM rather than a reply directly into this thread by Dale, and here is what he was saying:

@unknownuser said:

However there is one thing I would like to clarify.
I don't have a problem intersecting edges to a face as long as the face is not grouped (although the edges can be grouped). Is there another reason you are projecting the edges that I am missing.

After a quick test, it appears to me that I had completely missed this very first simple way

So would you please completely forget this tut!
In the future I shall give the next ones to test to some friends before to post them

Hey Simon
I still think this is a useful and valid way of getting a shaped hatch.
I have used your process , where we needed to put a hatch over a really weird shaped area on a topographical survey map to indicate the extent and effect of a construction development project.
By using exactly your method we were able to project the hatch through the topo, and intersect with it, leaving the hatched shape on the surface of the topo and then show it in a 3d view rather than a typical orthographic projection. With a little shading it really looked sweet.
So, I think the Tut. is a real showcase of possibilities for the rubies you used, and a valid process.
Cheers

Dear Dale,

You put my shame out!

Well Simon you have class.

Unfortunately in my case the "Cl" in class is usually silent.
