Hatch to follow curved path

[marko_ribar]

Maybe, I don't know to manipulate so good with geometry??? I am arch., tried dlls on A2009 32 bit and it works, but I am unable to reproduce hatch Sean posted... My canvas block when select face has 2 shapes - inside shape follows curvatures and outside is boundary rectangle... When I hatch => explode and use "CVP" no deformations occurs - only lines have been transformed to splines... If only Sean can demonstrate with animated gif, what he did...

I think I figured out how to do it... Make solid with shape - half ellipse region positioned perpendicular to plline that is pedit=>splined as extrude path... NETLOAD => CPM => hatch => explode => CVP and that's it... Example I posted now is with half circle region shape and pline splined as extrude path with low number of vertices for curvature... But this explains whole process... It should project hatch on curved surface with CVP very fast... If it's slow something with surface is wrong - when unfolded result should always be rectangle...

yes...and it is limited to this hatch pattern only.
guess there is no way we can have hatch follow a path :sigh:

You can get an approximate picture with creating several blocks and using Measure.

But in the real world, paviors are of fixed dimensions and are solid, so if the client sees the paviors following a curved path, and wants what he sees, you are going to have terrible problems making customised paving blocks. Better the client does not see some clever drafting, and you realise that your vision is going to cost an awful lot to achieve. However, if you have an unlimited budget, then go for it.

If this is what you do for a living then go out and hire someone to write you a customized lisp program to hand the chore.

i did try hiring someone but still no avail

thanks. I have seen this already but im afraid it is not applicable

Yes, i kinda know him (well most LISP users should know him)
He has quite a good reputation in field of lisp programming
i haven't asked him yet
