hatches...
hatches...
does anyone have an idea how to tackle creating hatches? i know how to create the oddbhatch... but how do i pick the loop from a given point? or even how do i specify the loop from a set of selected entities? is there winding involved in the order of the loop edges? do they have to be closed? is there a sample you can point me to?
thanks much,
tyler
sergey,
i'm in this rather deep. i have implemented my own odhatchpatternmanager derived class and am parsing the .pat files myself. i've notice a couple of oddities that perhaps you can explain. one: the oddbhostappservices:atternmanager is not called when a drawing with a hatch is loaded. two: my pattern parsing of the honey pattern isn't coming out correctly when i display it in a preview. autocad def looks like this:
0, 0,0, .1875,.108253175, .125,-.25
120, 0,0, .1875,.108253175, .125,-.25
60, 0,0, .1875,.108253175, -.25,.125
it works correctly for me if i do this:
0, 0,0, .1875,.108253175, .125,-.25
120, 0,0, .1875,.108253175, .125,-.25
60, .125,0, .1875,.108253175, .125,-.25
of course... the load of a drawing from autocad correctly draws the pattern (thats how i noticed number 1).
thanks...

thanks for the insight...i'm not able to reproduce it using the odhatchpatternmanagerimpl code base. i must be doing something wrong with the dashes.
well... i found my error. i forgot to clear out the dashes list...so each subsequent line i parsed got the prior lines dashes. whoops!
thanks sergey!
