Hide Edges


I have a simple question. If there are two walls one above each other how can I hide the edge between the two elements?

I tried number of things: Tangent edges is not working in V6 because they are two separate objects. Boolean also cannot be used because the two walls are two different type but only the render is identical outside.

Hello - none that I know of with two objects. If you need one thing there and they are boxes, it should be easy enough; with two things, I guess you get the line.


Why not like this pic.

Think about the physical objects you are representing: in most materials you will see a line unless you cover the surface with a continuous material (e. g. paint). So your cladding surface is actually a realistic solution.

why dont you just turn off surface edges and make a quick bounding box with output curves,
if you need the outlines. dont forget to check “render curves” if a rendering is what you need.


It would nice to have a “hide surface edge” option. That would make drafting really nice in rhino. Having to do it through the display properties does not allow enough graphic customization.

I hope someone from mcneel sees this.

It is easy - make new display mode and set its edge thickness to zero, as shown in the following screenshot. (You have to set shading settings to something visible. If the shading settings are invisible, you will be editing invisible objects.) Rhino Options command is used to make new display modes.

The following screenshot depicts two boxes made with Rhino Box command. The boxes are stacked on top of each other and their edges are invisible.

I specifically said that i’m not talking about changing the paremeter of display modes. Playing with display modes is actually what we currently do at the offiche.
It would be nice to be able to hide a selecteed edge whitout turning of the visibility of other surface/mesh edges. Sometimes you want to hide certain edge that don’t have any meaning in the drawing.
And i also know it s also possible to assign different display modes to different objects, i’m not talking about that.

This would be very helpful for drafting since it will allow exporting quick views without having to edit the result because of visible polysurface edges for instance.

for instance, i would like the red edges to be visible and the blues ones to be hidden

Hi -

For something like that, Make2D is your best bet.

SetObjectDisplayMode the object to renderd, dupedge any edges you want, (takes you 10 seconds or less, dont think this is a meaningful setup though :smiley: )

The purpose of being able to hide edges directly on display is to create quick views and drawings, by printing the display instead of having to duplicate edges or making 2d drawings. Especially ofr architects and urban planners.

It’s really convenient to be able to custumize edge display directly on screen.
I’m not lokking for a tip to show edges by duplicating them, but about the display on screen.

I said previously that i’m not talking about ways to change display modes of objects or tips to duplicate the edges. But a way to directly hide or show edge display on screen.
That would be really covenient for quick views and quick drawings directly printed from screen display.

Skecthup has that option for instance

what is the difference for you if the outcome is practically done with the same effort?
i have SetObjectDisplayMode configured to shortcuts, now if you make a macro for alltogether in the end its just activating click click* done.

The real difference is this ==>

Setting the display mode of an object allows you to hide all of it’s edges, but you cannot hide the display of a specific edge if for instance you don’t want it to be displayed.

that is all clear to me… but the above is a practical workaround. maybe duplicating the entire boarder and then deleteting the ones you dont want to see makes more sense? in the end you activate something and click around, the same effort more or less.

i mean dont get me wrong, if somebody is willing to enhance the display modes to show and hide individual edges, so be it.

When you work with urban models and different architectural project it can quickly become really messy to duplicate and hide edges just to tweak your display.

Being able to hide edges seems like a small tweak but i would be a huge improvement for rhino, espacially for drafting and documentation.

ok, but how often are you drafting out the entire scenery for a model? maybe once if you are not a total shrink head :slight_smile: and then as @wim pointed out, Make 2d might be your best guess. fiddling around at each corner of a huge model repeatedly does not make any sense at all if i think about it.

but ok i dont want to undermine the way you work.

I agree. I believe this is the most powerful feature of Revit. Hide edges. Sketchup also has this feature. Maybe even better that Revit.
I don’t wand to see an edge between a concrete slab and a concrete column but at the same time I don’t want to join these together. I want two separate objects. I don’t know how difficult is that but its a must.

Investigating more this feature in SketchUp (which I never use just convert for some students) I discover that it’s able to place edges of an object in different layers that faces. A very powerful feature I would love to see in rhino
