Convert block or polyline into a custom hatch pattern.

[Mrijzewijk]

Hello,

is there a way to convert a block or polyline into a custom hatch pattern ?

I want to creat a view of a roof, filled with a type of rooftile only found here in the Netherlands.

Thanks for your help.

Best regards,

Marcel

Not in LT, you can certainly create a custom hatch, but they consist of line segments only. If you want to use a block of a roof tile then maybe look at the array command (but that will only use full blocks - no halves at the edges).

How much detail do you need/want to show in the hatch, would it not be possible to just adapt an existing hatch.

[Mrijzewijk]

I made a dynamic block with an array option and clipped it so size, which works fine.

But it seems to me that hatch is a better option.

Not much detail, a simple single line block should be more then enough, 

Adapting an existing hatch might work, although i haven't found a suitable pattern yet.

Thanks for the tip !

Can you show us an image? A single line block is very simple.

Here are 3 types i did earlier, with a double line at the bottom.3xrooftile

A hatch can only contain lines, so no curves, you would need to break those curves down into short line segments to create a hatch pattern like that. Have you tried a google search here's just one site offering free roof tile hatches

Ok thanks, i will have a look.

The hatch would need to depict properly sized tiles as laid.

Could you post a full-scale R14 DXF of the tiles (curves and polylines are ok)?

@hugha , sorry, i can only save to R12 in LT 2021 (or so it seems.)

R0012DXF is lower than R14DXF, so saving it further down should work just fine.

For some reason i can not add an attachment 

So used a wetransferlink: https://we.tl/t-LNTu40uvv3

Thanks again.

Ok, DXF shows three individual tiles in plan so have sizes if leftmost tile is ~218 wide.

However each must be trimmed to hide what's hidden.

How does each overlap

• vertically?
• horizontally?

best,

Hugh

@hugha 

There is no overlap.

A finished hatch should look something like this. 

Bottom row is a simplied version without the double line.

Hi,

thanks, that simplifies the job.

See attached for double lined versions butted both ways.

@hugha 

Thanks a lot.

Tile 2 looks quit good.

How did you make the patterns ? 

Best regards,

Marcel

It's straightforward:

1 open DXF in HatchKit,
2 drag Entities into three separate pattern editing windows
then for each:
3 delete other than target tile
4 arrange, butting tiles at top and sides
5 remove unnecessary repeated lines
6 save to named .PAT

That's it.
