custom hatch pattern

thomas.middendorp — Thu, 05 Mar 2020 13:58:31 GMT

Hello,

I am trying to make a custom hatch pattern voor a brick wall.

The horizontal lines are no problem, the work great, but the vertical ones do'nt add up.

They are nog positioned the way I though I typed them in to the *.pat file.

For some reason they shift in the vertical direction, but not in a disctance that I set it up.

Can someone please give me some advise

thans a lot

forgot the *.pat file

*BLOK, blokpatroon fbc
0, 0,0, 108.5,106, 207,-10
0, 0,43, 108.5,106, 207,-10
0, 0,53, 108.5,106, 207,-10
0, 0,96, 108.5,106, 207,-10
90, 0,0, 217,0, 43,-10,43,-116

I forgot the *.pat file:

*BLOK, blokpatroon fbc
0, 0,0, 108.5,106, 207,-10
0, 0,43, 108.5,106, 207,-10
0, 0,53, 108.5,106, 207,-10
0, 0,96, 108.5,106, 207,-10

90, 0,0, 217,0, 43,-10,43,-116

I know there need to be more vertical lines written, but the first is already wrong so I need advice first

A confusing thing about Hatch pattern definitions is that for linesets at other than 0 degree angles, the origin point is still defined in relation to the 0-degree direction, but the X & Y offsets are defined in terms of the rotated direction. I think [without trying it] that your 90-degree line:

90, 0,0, 217,0, 43,-10,43,-116

should have its offsets done differently, something like:

90, 0,0, 106,108.5, 43,-10,43,-116

[reversing the X & Y offset numbers from the horizontal lineset definitions, because of the 90-degree rotation], and then another for the other sides of the vertical joints:

90, -10,0, 106,108.5, 43,-10,43,-116

But I think the verticals can all be covered in just the two lineset-definition lines.

... and having tested it now, I find those lines do work:

*BLOK, blokpatroon fbc
0, 0,0, 108.5,106, 207,-10
0, 0,43, 108.5,106, 207,-10
0, 0,53, 108.5,106, 207,-10
0, 0,96, 108.5,106, 207,-10
90, 0,0, 106,108.5, 43,-10,43,-116
90, -10,0, 106,108.5, 43,-10,43,-116
