Hiding edges on tangent surfaces

[rocheey]

Im generating 2 simple tangent planar surfaces, which share a common edge, but not necessarily the same plane. The idea was to treat these as one surface (a "vee" shape of surfaces, if you will) and hide the shared common edge: definitely hidden in the drawing, and hopefully hidden in the model.

KNIT allows me to treat them as one surface, but Im still having trouble hiding the shared edge. As soon as I attempt this in the drawing,the entire view turns a blue color, the line width turns very thin, and still a second "hide" is needed to hide the edge: but only if the edge is 'frontmost': any edges that are already clipped will not hide at all, and sometimes hide an edge unrelated to my selection..

Im willing to try just about anything here, API, other surfaces, etc, with the exception of using some memory-sucking, mutifaceted NURBS mesh to generate what should be a couple of simple faces. Any takers?

if i understand your question correctly, i think what you want to do is possible by doing the following; create your first surface using the sheet metal base/flange tab command. create your second surface by using the edge flange command and define the angle of your "v", changing the default bend radius to be as small as possible if you want a sharp "V".

now to get the model to display without a line at the bend go to Tools/Options/Display/Selection and turn off the HLR edges in the shaded mode. to do this in the drawing, right click the view and go to Tangent Edges and select "Tangent Edges Removed".

hope that helps,

Well, although this is a sheet-metal related Part, what I am generating is not a sheet metal SOLID MODEL, but a *SURFACE MODEL*, apparently not-so-much-used in SW.

But thanx for your reply.

i had not used the surface model features of SW before, you are correct. i did try this problem though, and i think i was succesful. i drew simple 50mm x 50mm rectangle on the right plane and used that as a bounding box for a planar surface. i then inserted a reference plane at a 45 degree angle to the right plane and sketched another rectangle on that plane, having it share a common edge with the original surface. again i used *planar surface* to create my second surface. now with two 50x50 surfaces at a 45 degree angle to eachother i used knit surface and then filleted the common edge with a very small radius fillet. with tangent edge display and hlr edge display turned off in the display/selection page of system options, the only way i can tell that they are two seperate faces is because the color of the shading is slightly different.

if i haven't understood your question, sorry to waste your time. i'm glad to have gotten around to playing with the planar modeling commands though.

cheers,

This worked like a charm, even though I realize now that I asked the question wrong (I was referring to surfaces with
*concident* edges, not tangent edges), but your solution worked great. Thanx again.
