Fusing Grids Together

[aspect]

hi all,

would like to know if i apply a polyspline to a grid like this-

http://farm1.static.flickr.com/204/4995511...7ce89b344_o.jpg and manipulate

then i merge the grids of "before and after" the

polyspline, http://farm1.static.flickr.com/212/4995511...9a47389fb_o.jpg ,

how do i 'fuse' the two grid together cos right now at merge sop, the

primitives of both grids are overlapping.

Is there any sops to merge two grid of different pattern together or am i

being wishful thinking?? *i tried the fuse sop but not seem the primitives at merge sop still overlapping.

thanks.

How do you mean "fuse" together? Do you want to have the polysplined version as holes in the original? fusing just means remove shared points.

It sounds like what you need is to skin each pair of polygons one from the original and one from the polysplined version? If that is the case you might find you need to divide the edges on the non-polysplined one so that they have the same number of points otherwise things could get messy.

After the Merge SOP append a Hole SOP. That will bridge the many closed faces to the grid that built them. A great way to make punched steel mesh grilles.

If you want to fill the holes, just merge back the closed faces and fuse.

edit: If the pieces to hole lie off the grid for what ever reason, increase the Distance Tolerance until you get fusion again. The Angle Tolerance is used if the holed faces aren't quite perpendicular.

The Hole SOP is darn handy and greatly under-used in poly modelling.

dear all, thanks for the reply.

my intention was to mainly fuse two type of grid into one grid, http://farm1.static.flickr.com/204/4995511...7ce89b344_o.jpg so i can select individual primitives to make modification like: delete sop, primitive sop. becos right now i simply merge the sop together and the primities are overlapping.

oldschool> ha, in fact i did use hole before, however, this is the ideal case when i use bpline in the the polypline sop: http://farm1.static.flickr.com/212/4995511...9a47389fb_o.jpg , and making hole was succeedful in this particular case.

however, if i use beizer in the polypline, the hole sop didn't work, http://farm1.static.flickr.com/232/5009142...9afa218cb_o.jpg , i figure if i can fuse the overlapping grid together, i can select which primitives i want to delete or to add primitive sop to transform individual primitives.

You can't mix bezier and polys in the same object and then use the hole sop, stick to polys only.

You can do all the things you want with out fusing - once they are merged all the primitives are all together and you can apply operations to all of them or just a selection.
