How to bevel around the edges of tiles

[Daniella1985]

I can only do the top side, I can't handle the other three sides. Can I just input the cutting angle? The black one is a cube. I also want to cut it, how do I use it? I don't know how to use those commands

*) For cutplane perpendicular to xy: cutplane{2} needs 2 parameters according to the manual

*) cutplane needs a cutend, and all geometry should be between. See examples in manual
*) Not sure why the bottom cut doesn't work. My guess probably object is moved up and the cutplane is below:

ADD x_cut_start, 0, z_cut_start
BLOCK tw_cut2, tile_t, th_cut2
DEL 1

*) would avoid cutplanes and booleans in general if possible, depending on the situation.

[Lingwisyer]

Should not your bottom cutplane have an extra 180? I found it easier to manipulate a basic cutplanes and rotate those with basic transformations instead...

I have a new project: how to cut a 3D floor at a 45-degree angle, like a floor tool. I'm having trouble; I've failed many times with the syntax.

tile_tah_end = tah_end
cut_tax = tax
cut_tay = tay
cut_taw_end = taw_end

IF chamfer_on THEN
cut_tax = cut_tax - chamfer_l
cut_tay = cut_tay - chamfer_b
cut_taw_end = cut_taw_end + chamfer_r

CPRISM_{2}, CPRISM_{3} & CPRISM_{4} will allow you to set materials and an angle to each edge of the PRISM.

No need for cutplanes.

Barry.

[Lingwisyer]

As long as you are pivoting from the x-y plane?

[Barry Kelly]

The edge angle originate from the top surface of the prism.

0 is vertical.

Positive figure extends base out.

Negative angle shrinks base in.

As Daniella is modelling individual tiles, a bit of clever scripting will be needed to control the edge of each tile, so only the outer tiles are affected.

I would model one big slab for all of the tiles and then add lines to represent the individual tiles.

Or model individual tiles in a loop (as has been done) and add cutplanes outside of that loop to cut the overall mass of tiles.

Barry.

[AllanP]

There is an easier way to bevel each tile.

FPRISM_
FPRISM_ top_material, bottom_material, side_material, hill_material,
n, thickness, angle, hill_height,
x1, y1, s1,
...
xn, yn, sn

Similar to the PRISM_ command, with the additional hill_material, angle and hill_height parameters for forming a ramp on the top.
hill_material: the side material of the ramp part.
angle: the inclination angle of the ramp side edges.
Restriction: 0 <= angle < 90.
If angle = 0, the hill side edges seen from an orthogonal view form a quarter circle with the current resolution (see the RADIUS command,
the RESOL command and the TOLER command).
hill_height: the height of the ramp. Note that the thickness parameter represents the whole height of the prism.

si: status code that allows you to control the visibility of polygon edges and side surfaces. You can also define holes and create segments
and arcs in the polyline using special constraints.
Restriction of parameters:
n >= 3, hill_height < thickness
See Status Codes for details.

I hope this helps.

[Lingwisyer]

Only works if you are wanting to bevel all of your top corners the same amount. Given that they have toggle for each of the four sides, I assume this is not the case so FPRISM_ will not work...

[Piotr Dobrowolski]

If the bevel angle is about to be equal...then why not use the FPRISM_ or HPRISM_ commands? (EDIT: sorry did not notice the whole passage about them above)

I used that for my tiling objects/accesories.
