Edge extrusions? // New Users

I'm working with a tutorial that involves starting from a single rectangle and then expanding outwards through extrusions performed along the edges of the rectangle. It's not really a "face extrusion", which I can accomplish easily.
It's selecting an edge of a quad, then extruding along the normal to that edge, to create a new face beside the one already built.
Being relatively new to modeling and *very* new to Truespace, I'm wondering if there is an easy way to do this in Truespace. So far, I've only been able to accomplish this in one of two ways. The first is to grab the egde, drag it along the entire length the extrusion, then go back and add an edge where the original edge was located. This doesn't work if the vertices of the edge are connected to other faces, because it changes the location of those vertices as well.
The other method is to select the face, make a copy of it, drag the copy beside the original face, and then weld the forward vertices of the old face to the rear vertices of the new face. This works, but is painfully time consuming.
If anyone knows of an easier way to do this I'd be very appreciative. If not, then maybe I should post in the wish-list forum. :)
I'm doing all my modeling in workspace view (or at least as much of it as possible) because it's the "way of the future" (tm).
Thanks,

What version of truespace are you using?
Its not possible (unless there is a plugin?) in 6.6 or lower. I think you can do it in 7.5 workspace although you will find that tS probably puts in extra vertices that your tutorial for another program won't be expecting.
EDIT: I only just absorbed your last line about the workspace.
I thought you could use the extrude function on vertices and edges or is it just the bevel function that now does that? |

Hi Dlangar,
7.5 doesn't support edge extrusion in Workspace. The polytools plugin does do it in Model side/6.6 though.
This is a feature request for 7.6.
A workaround that you can use is to draw an edge next to the edge you want to extrude from, then just pull out the old edge as if it was being extruded. ;) |

Edge extrusion seems to be a long running request and I would definitely like to see it in tS7.6, even if it means waiting a bit longer for release. Would be great for making organic (i.e. character) models from orthographic images scanned in.
Pleeease can we have it? Can't be that hard to implement surely...:o |

I know there is no "Official" Statement but is the following not correct? I thought once Roman told us something was in ts7.6 Beta Testers could then be allowed to discuss it.

Nice quote Steinie:
"We already added edge tools and we are working on vertex animation tools.
I am very interested in hearing about ANY workflow problems in TS7.5 it is a priority for TS7.6 please let us know about anything you do not like".
Worth raising that point again, however, it does not mention edge extrusion...just 'tools'. |

Thanks for the replies! So yes I would definitely like to +1 the request for this feature. I'm using TS 7.51. I'll definitely check out the polymodeling plugin on the model side, though in general I am trying to avoid modeling on the model side because I find the bridge to be.. what's the word.. "unpredictable". But we do what we have to do. I still find the mirror tools on the model side to be superior, for reasons I don't understand, than those on the workspace side.
As for the suggetion to draw an edge beside the new edge and then drag to that edge.. my experience has been that you can only draw edges on top of or inside of existing geometry, correct? I haven't been able to create new edges or vertices or polydraw anywhere that wasn't already already a part of the existing mesh, so maybe I'm missing something.

Yeah that's the key to the trick, you draw the edge on the existing polygon just inside the outer edge then pull out the the outer edge.
When I get on my main computer later, I can upload a video. |

Here is a simple technique i tried (and it worked - no plugins needed, just Truespace 7.5):
1. Create a nurbs mesh (like a simple head, box, or plain). I used the plain.
2. On the modeling side there are tools for NURBS sufaces, including curve tools. Make a cuve with any one of the curve tools. Left mouse click to make points. Place the first point near your NURBS surface, where you want to extrude a curve shape.
3. Use the Extrude tool that pops up when you select the nurbs curve. To make the extrusion, click on your curve, then the extrude tool, then move the mouse up or down for your extrusion.
4. Click the Blend Surface tool next to the curve tools in the modeling side, then your curve, lastly, the edge you want it connected to on the nurbs surface.
5. Convert the surface to polygons with the same drop down menu of tools as the Blend Surface tool. There should be a tool called 'Convert NURBS Patch to Polyhedron (or curve to polygon)'. Click your NURBS suface, then the tool to convert it to polygons as mentioned above.
Here's how I extrude edges with polygons:
1. Make a polygon mesh (could be any mesh/model) on the model side.
2. Make another polygon mesh/model (like a separate piece of a polygon model. Use the glue as sibling tool to glue the meshes together.
3. Go to the workspace side, and there is a tool in Truespace 7.5 called Polygon bridge/Blend. Select your object, and then the polygon bridge/blend tool. Next select the first vertex/edge/face you want to connect to another part of the mesh, and then select the other part's vertices/edges/faces, and press Enter on the keyboard.
Hope that helps!

I would also add my vote for this command (extrude edge). I would also suggest that the windows standard keys be made to work like most windows & graphic programs. Example: If I select a face of a cube and hit the the delete on the key board, in Ts the entire object is deleted, instead of the face (currently selected item):o, same is true for edges. Also this my be just lack of knowlege of using TS, but if you have a simple cube that has one side/face missing you can not select a face thru the open side untill you rotate the cube so that its outer face is facing you. |
