lattice/deck skirt?

Patrick M — Thu, 02 Jul 2026 19:15:25 GMT

does anyone have a lattice or deck skirt object that can be stretched to fit and maintain a pattern?

I'm trying to avoid using the curtain wall at all costs!

Operating system used: Mac Apple Silicon

I would use the chain link fence surface material and adapt it for a timber lattice.

New symbol fill if you want it exactly as your image and a new texture with alpha channel.

I thought about that; but didn't want to deal with the transparency in elevation issues... that, and it feels cheap enough to show a lattice on a $6m house, even worse if it's a flat surface...
...

maybe some day when I get a ton of free time, I'll work on scripting something for future use

do you want it to be an object or a window?

do you want it to be just a rectangle or polygon?

the old draw a slab as the outline of the lattice,

then make the lattice oversized,

2d Script

project2 2,270,3

3d Scrpt

group "main block" block a,b,zzyzx endgroup group "lattice" addx 0-zzyzx*tan(angle1) for j_loop = 0 to a+(zzyzx*tan(angle1)) step (slat1x+slat1space) roty angle1 block slat1x,slat1y,zzyzx/(cos(angle1)) del 1 addx (slat1x+slat1space)/(cos(angle1)) next j_loop del top addx 0-zzyzx*tan(angle2) addy slat1y for j_loop = 0 to (a+(zzyzx*tan(angle2)))*2 step (slat2x+slat2space) roty -angle2 block slat2x,slat2y,zzyzx/(cos(angle2)) del 1 addx (slat2x+slat2space)/(cos(angle2)) next j_loop endgroup placegroup ISECTGROUP("main block","lattice") killgroup "lattice" killgroup "main block"

parameters

parameter script

b= slat1y+slat2y parameters b=b values "angle1" range[5,85] values "angle2" range[5,85]

that should work

I hope this helps

P.S.

add different materials for different sides

and to fix the 90 degree angle problem by,

make different rules for angles greater than 45, up to 90, (draw along sides rather than across bottom)

make rules for angles past 90, up to 180

then use modulo command for angles past 180,

group "main block" building_material slat1Mat block a,slat1y,zzyzx addy slat1y building_material slat2Mat block a,slat2y,zzyzx del 1 endgroup group "lattice" blockWide = slat1y blockHeight = slat1x blockSpace = slat1space building_material slat1Mat angle1a = angle1 mod 180 if angle1a > 45 and angle1a < 135 then roty 90 addx 0-zzyzx-zzyzx*(angle1a > 90 ) limitWide = zzyzx limitHeight = a limitAngle = angle1a-90 gosub "draw block loop": else limitWide = a limitHeight = zzyzx limitAngle = angle1a add 0-limitHeight*(tan(limitAngle))-a*((angle1a > 90 ))/cos(angle1a),0,0+zzyzx*(angle1a > 90 ) gosub "draw block loop": endif del top addy slat1y building_material slat2Mat blockWide = slat2y blockHeight = slat2x blockSpace = slat2space angle2a = angle2 mod 180 if angle2a > 45 and angle2a < 135 then roty 90 addx 0-zzyzx-zzyzx*(angle2a > 90 ) limitWide = zzyzx limitHeight = a limitAngle = 90-angle2a addx 0-limitHeight*tan(limitAngle) gosub "draw block loop": else limitWide = a limitHeight = zzyzx limitAngle = 0-angle2a add 0-limitHeight*(tan(limitAngle))-2*a*((angle2a > 90 ))/cos(angle2a),0,zzyzx*(angle2a > 90 ) gosub "draw block loop": endif endgroup placegroup ISECTGROUP("main block","lattice") killgroup "lattice" killgroup "main block" end "draw block loop": for j_loop = 0 to limitWide+(limitHeight*abs(tan(limitAngle)))*2+(blockHeight +blockSpace )*2 step (blockHeight +blockSpace ) roty limitAngle addz -blockHeight*abs(tan(limitAngle)) block blockHeight,blockWide ,limitHeight/(abs(cos(limitAngle)))+2*blockHeight*abs(tan(limitAngle)) del 2 addx (blockHeight +blockSpace )/(cos(limitAngle)) next j_loop return

The fist (simple) option was done at the end of a Friday just before home time, just the basics to survive from 5 to 85 angle.

Hopefully this is simple enough to understand/learn so other people can modify, develop their own in the future.

you could add features to....

change the origin,

change the main block to a polygon shape,

add a boundary around to tidy it up,

etc...

I have an object from 25 years ago I use all the time. It works fine as long as you are less than 8' high. I don't know if I can attach it, so if it is not here PM me and I'll send it.

Hi Allan,

I don't know about @Patrick M, but I loved it! Works great, except for 90 degrees angles. In other words, if the screen has horizontal and vertical slats. AC crashes if one value is to be set to 90. I suspect it is because of the tangent function in the 3D script. Any way of fixing this?

I could do 89.5 and it works. 85.99 degrees crashes! 🙂

Thank you,

I hadn't thought of a custom leaf/sash! great idea!
