Hatch Pattern Help

[gottfriedjoseph01]

I am trying to create a hatch pattern that is in accordance with the general c.m.u. block section of the company I work at. I am struggling to create a hatch pattern that reflects the image. I attempted to create a code for the pattern but I have failed and can't figure out why. Please help.

How much of that is meant to be part of the Hatch pattern, as opposed to containing linework?  Just the white parts?  Show us an example of how it should look over a more extended area.  Would such an extended area be extended only vertically, such as in a wall section?

EDIT:  As an aside, in my decades as an Architect, drawing and receiving things like wall sections with CMU shown in them, I have not typically seen it drawn with the actual face thicknesses, but rather as just diagonal cross-hatching.  I have a Hatch pattern that does that and includes the joint lines [at standard 3/8" joint width and 8" spacing]:

All the white parts are part of the Hatch pattern.  The origin is at the top of a block / bottom of a joint.  [I also have it with a single line for the joints and larger diagonal spacing, for smaller scale drawings.]  The same pattern is used for any thickness of CMU [6", 8", 12" shown], whereas something that does the face thicknesses, like what I think your image shows, would require a different pattern definition for every possible CMU thickness.  And still more different definitions if you deal with different face thicknesses such as for varying fire ratings.  But that's all possible....

I'd like to see the hatch pattern you're talking about, the one with the 3/8" joint and at 8" on center. below is a typical wall section. The white lines are supposed to be the hatch pattern and the pink lines are the outline. Also I work for a structural design firm. We are trying to figure out ways to draw our sections more accurately. I figured a wall hatch that would be less time consuming. thank you.

Why not array a block vertically ? Much easier and no code required. The total detail could be done via a lisp including all notes and the concrete footing including reo.

Here's that pattern:

*C-SE-2,CMU Section Double-Line
0,0,0,0,8
0,0,.375,0,8
45,0,0,0,1.5
135,0,0,0,1.5

The Array-a-Block suggestion makes sense to me, also, or MINSERT a Block.

But what you show could be done.  What should the face thickness be?  Would there need to be different versions as described in my previous Reply?

I think this answers your question about face thickness.

Well, once worked out for one of them, it was a simple adjustment of a few numbers to get the rest.  See the attached.

Origin point should always be at the lower left.  And they should be used only within the intended width for each variety -- the "look" gets peculiar if wider than that.

The joint lines are included [all the white in the image].  The little horizontal hacks are at 1" spacing, with the joint thickness taken out of the bottom space [yours were similarly different at one end].  It would be possible to have them equally spaced across the height of a block, but it would require considerably more pattern-definition code.

Note that the origin is at the bottom of a mortar joint, and should go on whatever the first course is laid on, with the mortar setting bed covered in the Hatch pattern [unlike your image of some right on a concrete footing with no mortar setting for the first course, which would not be the case].

Thank you so much this is exactly what I was looking for.
