Hi,

I have some polygons in a line. Now I want to to make a cut from on vertex (above) to one vertex (down) through all selected polygons. Is this working? If yes, how I could do this? 

Thanks in advance.

cheers

Humm, you want to divide your object in two? Is that? YOu can use edge tools to do that... can you describe better what you want? (Sprry my english isnt that good)

Sorry Wal, I don't understand your question either.

The question is can Carrara do Tesselation by Slice the way Hexagon can?

There are edge tools and tesselation tools in Carrara also.

ShawnDriscoll ( ) posted Thu, 10 December 2009 at 6:23 AM

Neither one of those is the right tool.

If you dont explain better what you want to do we just cant help you. Those tools that I am pointing in the image are for tesselation and to add edges, so you can cut, add and tesselate polygons.

The answer is no then.  wal3d will have to use Hexagon or something similar like Silo which has more advanced Tesselation tools.

Well if you cant explain better we really cant help, bu even if the tools doenst exist dont mean that the software cant do...

I know a way that's easy:
Export to .obj from Carrara... 
Import to Wings 3D.
And then Tools | Cut  from the dropdown...
Do whatever...
Export to .obj again.
Import back into Carrara.

But then again, this method would work similar with Hexagon, Silo, Modo, etc...
Still involves going outside of Carrara to use a complimentary modeling app. And I can't remember if Carrara tesselates to tris on export, which might make a little bit of extra cleanup work.

 Hi.

First of all I have to say thank you and sorry for my delay. I had no chance today to answer erlier. But now, I'm back ;) 

What I'm looking for is to find the right Tool to cut polygons starting from one Vertex or Edge to another (opposite) one.

I know this from other tools and there it is often called "knife" or "saw" or something similar.

Attached there is another picture of what I mean or looking for.

I  want to cut the selected polygons in that way, that I click first the Vertex 1 and than the opposite Vertex 2. The result should be a new edge straight to all the polygons (under the green line).

Just to have something to cut polygons in different pieces.
I hope the picture will explain it good enough.

Thank you in advance.
wal

Hi Wal3D, Carrara you have to use the ADD point tool. One fun thing about this simple tool is that when you are right under half of the object, your cursor will tell you.

wal3d ( ) posted Thu, 10 December 2009 at 3:17 PM

Hi GKDantas.

Thanks for this tip. Yes is works ... but only as a hard workaround. But if I have more than these some polygons like you can see - it would be a hard work to do it in this way.

I think the others are right to use another tool for modeling. Cuts and Loop-cuts and so on are most important if you will do (hard surface) modeling.

But thanks again for showing me that workaround.

cheers

GKDantas ( ) posted Thu, 10 December 2009 at 3:23 PM

My hope is that they add more tools from Hexagon in Carrara too... in Hex is very easy to do that.

 Hi GKDantas.

You're right ... Carrara has some really cool modeling tools ... can't believe that tools like a knife or something similar are missing. So let us hope ... ;)

Is the wrong tool?  Yes.

Brian, he wants only to cut the object in the middle... nothing more. Maybe a boolean could do the trick too.

We need a contest here to see who can come up with the longest workaround possible to get the job done.

A simple Carrara 3D Boolean? Brian

Wal3d,

  I have asked before for a Knife or Cut tool but we didn't get one , oh well.

  There is something that people may not know about the Extract Along command, it works well with  polygons as well as edges. So select a group of edges, click the Extract Along command and click polygons and drag to extract edges and then  finally scale edges to be zero in the appropriate axis. 
  You can do the same for your edge sample but you would have to weld the result with a very small tolerance as you would have vertices on top of each other at the Top and Bottom of your sample object.
  Here is a pic of what I mean. Hope this helps.

Hi Mike, I saw this in the Carrara 5 manual: CUT TOOL!

Create a poly line and place wher eyou want to divide the object (dont need to be inside the object, above or down works too). Click in the small arrow below the Boolean tool and select the Cut tool.

Now select the object and after that the poly line, use your "-" or "+" keys to choose your cut option, them hit enter, its done. Simple and sweet.

Yes Brian... and since you can use poly lines you can cut with any shape you want to!

ShawnDriscoll ( ) posted Thu, 17 December 2009 at 6:56 PM

Now to get it to not cut the entire object in half?

Yes , now that you mention it I remember that .   I wonder why I never use it......

 I just checked and the Cut tool you mention works the same way as the Boolean Cut tool so the edges that you "cut" your line  through(interior edges) get destroyed as well as cutting the object in half like was mentioned by ShawnDriscoll.

Of all the posts on this thread there seem to be a series that interpret as being criticisingly unhelpfull, negative ones?

 Dissapointing.

so Brian, you are a type of Turkish bread?

A cut tool would make box modelling a lot easier.

If the question is; "Agree with me that Carrara lacks a tool I think it should have," then there isn't much point in trying to be helpful.  Sure, Carrara could use more tools.  And better versions of some of the ones it has.

If the question is, on the other hand "I have a modeling task and I'd like to try to do it without leaving Carrara," then there are answers.

For me it would be a couple of steps.  Marquee to select one edge of the item, edge tool to select and extract an edge and drag it to approximately where I wanted it, and then scale tool to make it planar.

I've done the like many times.
