Fun With Hatch Patterns - Episode #20220001

[bwhisenhunt]

So I've been asked to create TWO hatch patterns as shown below.  I have Hatchkit but have never had to do anything other than standard brick/tile layouts.  I haven't found any good information online on how to create something like these with Hatchkit.  Any help would be greatly appreciated.  Also if there is any information on how to do this with Hatchkit that you know of, please let me know.

For the first one, I don't think those dimensions can be correct.  They make something proportioned like this:

If the larger tiles should be approximately regular octagons, the diagonal of the square ones would be about 1-11/16".

I have something similar in yet different proportions, that could be adjusted to whatever you really mean:

For the second one, you don't need a pattern definition.  Just do a User-specified Hatch, at a scale of a foot and rotation of 45°, and Double-direction:

HATCHKIT support is over here http://hatchkit.com.au support@hatchkit.com.au

SUPERHATCH command is another built-in method, help yourself https://knowledge.autodesk.com/support/autocad/learn-explore/caas/CloudHelp/cloudhelp/2021/ENU/AutoC...

Second issue:

Since you point out the colors of tiles, is it your idea to have the stone texture & shading incorporated?  You can't do that with a Hatch pattern in AutoCAD [whether or not via Hatchkit], but you could do it by defining a Block incorporating images or different-color solid Hatching, and using SUPERHATCH to fill areas with it.

EDIT:  But in an experiment [with an image file I had handy, not your tile textures], I find that if an image is part of a Block used in SUPERHATCH, while the linework elements of the Block show only inside the bounded area, the image part, if any of it falls within the bounded area, appears in its entirety, extending outside that area [the larger Circle here]:

How about creating a custom .pat as shown above?

*CUSTOMTILE, Hatch description
0, 1.41421356,0, 0,8, 5.17157288, -2.82842712
0, -2.58578644,4, 0,8, 5.17157288, -2.82842712
90, 0,1.41421356, 0,8, 5.17157288, -2.82842712
90, 4,-2.58578644, 0,8, 5.17157288, -2.82842712
45, -1.41421356,0, 0,5.65685425, 2, -3.65685425
135, 1.41421356,0, 0,5.65685425, 2, -3.65685425
225, 1.41421356,0, 0,5.65685425, 2, -3.65685425
315, -1.41421356,0, 0,5.65685425, 2, -3.65685425

The first code line must start with and asterisk, followed by the uppercased hatch name, a comma and some description.

Each following code line represents a geometrical line in which the pattern is subdivided.

In this case, we'll need 8 different lines.

Each line sintax is A,B,C,D,E,F,G where:

• A represents the angle expressed in degrees.
• B and C are the line starting point coordinates (X,Y).
• D and E are the next line starting point coordinates (X,Y) respect of the previous B and C.
• F represents line's length.
• G determines the gap between each line.

Hereinafter, please check the attached file and captures:

But using Solid Hatch patterns in a Block, to at least get an idea of relative shades if not of texture, does not have the problem [Block inserted at lower left, Superhatch using that Block in a Circle]:

[bwhisenhunt]

OK, I have never used "Superhatch"  I will need this pattern to work in both Autocad and Revit.  Is that possible?

If just the linework part, both can use the same kind of pattern definition.  The >example in Revit Help< may be almost exactly what you want [though at slightly different size? and with the square parts being what's orthogonally oriented].  Revit doesn't appear to have a SUPERHATCH equivalent.  Applying a material might be usable in both, though I'm not experienced enough in Revit to say for sure.

As @Kent1Cooper points out, vector hatching cannot provide shading which must be simulated.

The attached patterns employ crosshatching to simulate shading.

Both pattern templates were constructed from scratch with the HatchKit 4.2 pattern design tool.

HatchKit also imports fill template designs from DXF prepared elsewhere or compiles fill pattern specifications directly to Revit with the aid of the HatchKit Fill Manager add-in.

 

The attached patterns are suitable for either AutoCAD and Revit.

I hope this helps.  If we can be of further assistance please respond either here or where @pendean kindly indicated.

Thank you!   The TP-A will work perfect.  On the TP-B, there is an interior diamond that doesn't need to be there.  It should look like below.

Here are TP-A and TP-B drawn black on white without showing any construction grips or design aids. 

 

 

 

This previews their appearance as deployed.

[Look again at TP-B -- the larger tiles should be octagonal.]
