Title: Extrude vertices
Post by: jcue on February 10, 2013, 05:28:06 pm
Hello,

I have a background image I want to outline just using vertices but I'm not sure how to go about doing it. In blender you just create a plane merge all vertices into one and start extruding a shape. Unfortunately, I'm not sure how to emulate that same function in NVIL.

I used the "Creat/Inset" function and it worked for bit but it keeps crashing. Any insight would be appreciated.

Yes, it looks like the vertex create/insert is broken. But bugs do not normally remain long once reported.

For now, you could use the "Create Polygon" tool, which works in a similar way to the vertex create/insert. In polygon mode, press(hold down) "D"

Steve,

Thank you for the response. I will try the "create polygon" tool for now and watch for an update. Is there a way just to work with vertices (extrude) w/out having to create a polygon first?

Hi jcue,

Sorry, I do not know the workflow you mention (creating/extruding vertex without polygons).

You could use "object mode-> spline" to draw the outline, then deal with the spline later via extrude (you can set the spline to "Line list" if you prefer straight lines created by the spline)

I usually like outlining Letters and Logo's only using vertices. Once the outline is complete I then start filling it in with polygons.

Thanks for the help.

It should be ok in the new update now.
Title: Convert Spline to mesh
Post by: jcue on February 11, 2013, 04:58:26 am
Everything is working great now.


Is there a way to convert a "Spline" into a mesh/geometry?
Title: Re: Extrude vertices

There is basic streamline tool: Spline_Extrude. Hopefully it's what you want.

Thank you for the reply.

I found the "Spline_Extrude" tool but I think I maybe using it incorrectly. The problem is that the extrusion does not hold the splines shape. A specific example would be creating a roundish logo lets' say a pear. I outline the pear with the "spline tool" then I would like to convert that to a mesh (the curve outline converted to vertices around the pear) then all those vertices capped. The result would be one big n-gon. From there I can extrude that polygon for depth and I can bevel the edges...and create a logo fairly quickly. 

I have attached some pics.

There is no straight way at the moment.

1. Use the Spline_Extrud tool to create a tube like shape.
2. Cap the end hole and you get a big n-gon.
3. Select the big n-gon in polygon mode.
4. Geometry > Optimize or Divide NGon.

I will make a special tool for this.

I think next time around I will just add many more points in the "spline" before extruding it. This way when extruding the resulting mesh should hold the original shape a bit more. Thank you for the help I really appreciate it.

Hi jcue,

The problem is that the extrusion does not hold the splines shape.
Unfortunately, the spline is only extruded from the spline vertex points, so does not maintain shape when the points are far apart.
You can work-around that.
After creating the spline, duplicate it and move it up away (planer) from the first. Deselect both splines. Go into edge selection mode, select "Retopo" move the cursor over one of the splines until you see the cursor change to a "+" then LMB, move the cursor to the 2nd spline, and again, when the cusor changes to "+", ->LMB, press "Ctrl" (keep pressed) and move the mouse wheel to increase/decrease the number of edges.

Making a tool for those specific steps will not (IMHO) be helpful, unless there are already enough control points on the spline to maintain shape.

Steve,

Nice...thank you.

This helps a lot. It's a bit of an effort but it gets the job done  ;D . Nvil has a lot of features and it's always a bit difficult to learn a new program.

steve, it won't be a problem. I will make it a streamline tool, once the tool activated and the polygon is created, WMB can be scrolled to ajust refinement.

Yes, there are a lot of tools to learn in NVIL. It is a bit overwhelming at first, but IMHO, worth the time to learn.

Will that be a change/replacement to the current "Spline Extrude"? (you could add an option for capping ends?)

Hi IStonia,

I do not know, as I do not know what you are implementing.

If you are creating a specific tool to extrude/cap splines, then it could possibly be called "Spline extrude with caps", or " Spline solidify". However, if you are implementing in that specific way, it would be a specific tool with various limitations.(such as with the "Retopo" on Splines, where the tool expects only closed splines, and even if all splines are open, the resulting mesh is closed and does not extend to both endpoints of spline)

.

IStonia,

I know this isn't very imaginative but maybe "convert spline to mesh-outline". 
Title: Re: Extrude vertices
Post by: IStonia on February 11, 2013, 08:14:36 pm
I think it can be called 'Spline_Polygon'.

The spline extrude is mentioned several times in this thread. For some reason I cannot find it.

Yep a lot to learn, but wow it seems to get better every time I open it up.
kind of like finding money in your pocket you did not you had.

Hi johnnybevo

I'm a few days ago found interesting tools - "Tool Search". It is located in left side of screen.
Input the "spline" and you will see "Spline Extrude" and a other tools.

Thank you very much.
I am going to check it our right now.

Thanks again Molebox.
I knew the search tool was there, but just never looked at it.
after I spend a while learning NVIL I am going to make it my personal mission to promote it.
