How to create Isometric / Axonometric Brick or Tile Hatch Patterns for 2D?

[Anonymous]

As can be seen from the photo attached. The tiled, brick like flooring is aligned isometrically. I tried to do it after importing a 2D-Isometric CAD file from a SketchUP model, but the brick pattern on AutoCAD just do not align exactly as my isometric drawing. Adjusting the angle of hatch DOES NOT WORK. As it will only change the angle of either the Horizontal OR Vertical brick but NOT both...

Please help! Really desperate now...

>[The HatchKit patterns from @hugha are oriented for wall usage rather than floor, and the lengths of the bricks is not what you asked for.]

Good get, Kent.

In skewing the orthogonal pattern I neglected to also shrink horizontally to keep the skewed distance  215mm. 

Apologies to all for any confusion.

It's perfectly fine! U are already kind enough to provide me with a solution first anyway 🙂 Thanks a lot!

I'm trying to do the same thing, but at 45 degrees. Would be so grateful if someone knew the code for this? 

Brick 65 h x 215 w. I'm finding all the vertical lines are off?

Thank you!

For an oblique 45 degree projection try this:

That makes bricks only half-length.  [And note that its name starts with a zero, not an O, which threw me off for a while.]  Try this:

*Brick45-65x215, 45-degree bricks 65 x 215, no joint
90,0,0,-11.01406898,76.01406898,65,-65
45,0,0,0,45.9618135

And oblique in the other direction:

*Brick135-65x215, 135-degree bricks 65 x 215, no joint
90,0,0,11.01406898,76.01406898,65,-65
135,0,0,0,45.9618135

[And remember that if put into their own separate files, the file name needs to agree with the pattern name and the file needs to end with an empty line.]

This is amazing - thank you so very much!

I'm still finding the vertical lines slightly off though - the 135 version more so. How do you find that number to adjust the spacing between the lines? 

Thanks,

[hugha]

Are we there yet?

My pattern was intended to be applied to an oblique projection which I dimly recall is drawn half-length along 45 degrees.

I'm guessing that you are a long way from the origin.  Try setting the Hatch object's origin within or at least nearer to it [see the Set Origin item in the ribbon].

Not if it's axonometric.  That means that things parallel to the axis directions are at true length, just as with an isometric [which is just one special case of an axonometric] projection.

Hi Kent - that was the issue. Resetting the origin point has fixed this now.

Thank you for helping with this.

I need to achieve the same thing, however it needs to be at a 300 degree angle - if can someone provide the code for this that would be great! Brick 65h x 215w, no joint.

Thanks!

Do you mean like this?

If not, draw up the idea.

EDIT:  If that's what you're after, try this [untested]:

*BrickAxo300-215-65, Brick, Axonometric, 300°, 215x65 running, no joint
300, 0,0, 0,32.5
90, 0,0, 28.09773091,53.75, 65,-65

Origin is at the bottom end of a vertical line.

....  But I must ask -- are those the right dimensions?  The bricks in the floors in your image look like a longer proportion. ....

I realized that I would have more use myself for something like these with the bricks/tiles in a 2-to-1 proportion, which is about what they look like in the OP's original image.  The attached BrickIso... patterns are defined for that, with the interrupted line elements being 1 drawing unit long as defined -- use a Hatch scale number of whatever that size should be.  [I kept the same pattern names as before, so if you also need the 215x160 size, change some names somewhere.]
