chevron flooring hatch

[Chrissy.a]

Hello

 

I am trying to make a chevron hatch. I have got so far but cannot seam to get the points to meet between the chevrons. Can anyone help? 

 

The details are

45 degree angle

566mm x 106mm long plank, set out 400mm and 150mm apart. 

 

I have attached what I would like to achieve and what i have so far...

 

what needs to look like:

You'll need 5 or 6 levels. Draw a sample in Vectorworks from which you can take measures is the simplest approach.

If you make each level a different colour it is easier to visualize while creating a hatch.

These numbers will give you a chevron pattern but maybe not to the spacing you desire.

LVL 1 / 0,0° / 50.8,45° / 0.5 / 50.8,-45°

LVL 2 / 0,0° / 50.8,-45° / 0.5 / 50.8,45°

LVL 3 / 35.9,0° / 50.8,45° / 0.5 / 50.8,-45°

LVL 4 / 35.9,0° / 50.8,-45° / 0.5 / 50.8,45°

LVL 5 / 0,0° / 50.8,0° / 1.0 / 50.8,-45°

LVL 6 / 25.4,45° / 50.8,0° / 1.0 / 50.8,-45°

Have you tried mosa pattern generator?

You can generate many different patterns and export them as renderworks texture, image and even an hatch.

 

In VW2021 is under File/Import...

 

or you can access it here:

^ great !

 

But I think he needs a vector hatch.

Isn't there already any similar hatch available in default or service select libraries ?

I'm not firm in 2D things, but isn't there beside the Hatch option something like "Tiles",

where you can set any repeatable pattern ?

I couldn't do it in under 33 layers.

 

If my math is to be believed each diagonal line will have a collinear repeat every 2400mm x 2400mm.  So it takes 16 layers (2400/150) of lines going one way, 16 layers of lines going the other way, and 1 layer to do the vertical lines.

 

I don't personally know anyone who is actually good at creating hatches, so I'll be interested to learn if there is a more efficient way of doing this.

This thread has prompted me to have a go at something I've been meaning to do for a while which make a hatch to go with a clay pantile texture. However I now realise why I put off doing it for so long. I understand in principle what I need to do but I'm really struggling to understand the relationship between the lines in my sample drawing bot left + the 'start', 'repeat', 'dash factor' + 'offset' settings in the edit hatch dialog.

I have dissected existing hatches + done endless playing around with the parameters to try + understand how it works but am getting nowhere. I divided my curvy line into individual straight segments but I have no conception of how many levels will be required (or how I'd work this out) or how to translate the parameters for the lines in the drawing into the edit hatch settings.

I am quite happy spending the time building the levels if I knew how I needed to do it. Normally you can figure these things out by trial + error but not in this case for me at least...

Any guidance gratefully received

Thanks

Here's a parquet floor hatch in 3 layers

ok panic over I figured it out phew

Thanks all for your help. @michaelk @markdd thank you for sending hatches! I have v 2020 and can't seem to open these or import in favorites into resource bar. Is there a way I should be doing this? I get the attached error message. 

[markdd]

I have back-saved it to 2020Parquet floor (1) v2020.vwx

[michaelk]

Here's the one I did, backsaved to 2020 and 2019.

 

 

Hi @markdd.  Much simpler :-).  But it looks like yours is a square repeat pattern.  It doesn't have the 400 x 150 ratio in the pattern from @Chrissy.a's post.  (I could be misunderstanding her question.)

 

I couldn't figure out a way to do that specific pattern w/o 33 levels.  But I'm not very good at making hatches.😄

Hey @Tom W..  If you figured that hatch out, I want to see it!

[Tom W.]

Don't worry I'm still here scratching my head what a nightmare!

I qualify my previous statement: I figured out how the hatch editor works, which was great for a moment, until I realised how profoundly unsuitable it was for making the kind of pattern I'm after...

🤣🤣🤣🤣🤣🤣🤣🤣

I've seen some insane hatches over the years. I assure you those PanTiles are a synch!! I'll have a go in a quiet moment. Sadly no long train journeys these days which were excellent for figuring stuff like this out...

[markdd]

@michaelk

 

I didn't really understand the hatch spec so I freestyled it a bit! Surely it's just a herring-bone parquet which repeats after every other column. The image didn't show anything else that I could make out.....

[michaelk]

@markdd   Check out @Chrissy.a's first photo.  It doesn't repeat every other column.  I think it repeats every 6 columns.  (400 x 150)

Man if you can do one that would be amazing. It should definitely be possible. My experiments have it repeating over insane distances though + I just don't have the maths/geometry knowledge/brainpower to figure it out. I'm trying a much simpler more symmetrical version just to get something that works...

I would love to know how you'd approach something like this, just to get my head around it. This hatch for example has 980 levels!

I attached a little gift that I have used for years. Not sure where I found it and it was initially created with "AutoBad", but don't let that put you off :-)

It is a VW 2019 file. It does have a ton of hatches that would be a bit of a challenge to create in VW.

Creating hatches in VW requires a degree in quantum physics, and is one of THE most arcane tools in VW, in my opinion.

*You will probably need to scale them to suit your project, but that is easy.

There are only six columns in the photo? I just loaded the image into Vectorworks and traced it using the move by points tool and it repeats every other column....! Unless I am missing something obvious or not so obvious... 

[michaelk]

@Kevin K Thanks for sharing that.

 

Here's one that's I've been harvesting hatches from forever.  I'm hoping somebody who knows Kat will chime in to give her proper credit.

@michaelkWhat I do see is that the diagonal may never repeat exactly.....

[michaelk]

This is how I started thinking about it.  If you make a 400 x 150 grid then every line does repeat every 6 columns.

[markdd]

I don't think the diagonals ever repeat exactly. It may be better to make a Tile instead. So much easier and more accurate!!

[michaelk]

They do repeat.  

 

2400/150 = 16 rows.

2400/400 = 6 columns.

 

That's a 2400 x 2400 square so a 45º line will repeat perfectly.

 

Using Cartesian (not polar) coordinates:

Start the line at 0,0

Repeat at 2400,2400

Dash factor 1/6

Offset 800,0

 

Start the next level at 0,150…

 

It takes one level for each of the 16 rows going in the positive X direction.  Then 16 levels going the negative X direction.
