You mean as in software used for sheet metal purposes? That would be more a mechanical engineering kind of things which Vectorworks has more or less abandoned. It would be nice to have for some purposes but if I understood correctly based on discussions in other forums having a good sheet metal unfolding functionality takes quite a bit of programming.

Unless you are referring to a different kind of unfolding that I am thinking of.

No, unfolding or flattening of 3D objects is not what is meant by 'UV Mapping', which basically is "the 3D modeling process of projecting a 2D image to a 3D model's surface for texture mapping".

Vw2017 Guide - Textures Projection and Orientation

The rudimentary texture mapping options offered by Vw will not allow you to correctly texture a 3D object. Examples of which include a stretched NURBS surface like a table cloth, Subdivision objects, a piece of wood which has different textures along the long and short edge as well as the face. If you try to scale a 3D object like a 3D tree purchased from xFrog, the texture mapping does not scale with the 3D object.

@rDesignI was trying to get clear what Matt meant with his question about UV unfolding, as it seemed to me he was thinking of the unfolding as used in e.g. sheet metal design software. If that is the case then I don't think it will be implement in the near future because it seems to be a rather complex thing to do well.

That being said, there are some 3D programs that do have unfolding but it may be a somewhat different kind of thing than used in sheet metal design software, perhaps a "reverse UV mapping" (for lack of better wording) might be all Matt wants for his purposes and that might be easier to implement if that is what he meant with UV unfolding.

Were you thinking something like pepakura? Vectorworks can already do some unfolding using Model>3d Powerpack>Unfold Surfaces. Rhino is a little better and will label the pieces for you. But none of that is as complex as the custom pepakura software out there on the web.

Gotcha - I just wanted to help clarify for Matt what this wish-list item was discussing. You're probably already aware, but Vw already has a function to unfold NURBS surfaces but it is limited to surfaces that are curved in one dimension only, so it might have limited application for sheet metal unfolding. That is a very specialized functionality and probably not something to expect from Vw.

Thanks that is close to what I'm after. Wasn't thinking sheet metal folding more streamlining Vectorworks Model to cardboard model attached.

Quick look at Unfolding Surfaces  will certainly get us there a lot quicker than the method we used. Although output from roof is messy and general ever face was upside down which isn't so bad by the time we arrange to feed the laser cutter.

Oddly googling with vectorworks as a specific term for answers don't come even close to suggesting this feature in the program. Almost all answers said push model to free modelling program use UV-unfold command then print.  Which is where my question was coming from. Afterall have you meet any Architects who aren't looking for an excuse to buy a laser cutter and make models.

"Popular this month" is more based on thread activity and how recently it received votes than just how many votes or replies it has total. But no worries, the views I use catch everything, that section is just there as a convenience feature. It isn't the main go-to for which features are the most desired.

The main overview for votes is more like this:

I think that's a good idea. Especially since actual, manual full-fat UV mapping where you rip apart objects into a splayed-out view and manually apply images and properties onto them and then bake them back into a model is most likely not something we would implement flat out, since it's practically it's own job description, but really a "Detailed and indepth solution for advanced texture mapping" is kind of the point. for instance, I think it was ArchiCAD that added a texture painter that let you select surfaces of objects and map texture to them separately from other faces on the same object, or something similar that seemed a good middle ground.

(EDIT: Or that Ptex thing mentioned in the original post, which looks really good, attached example video:)

Hello

I'm new here but this seemed the appropriate place for this question, apologies if not.

 

I'm just learning to use the cabinet/custom cabinets tool in 2017, which is generally very good but- is there a way to map textures to the cabinet fronts? I don't seem to be able to use the attribute mapping tool to move the texture into the position I want.

 

Thanks

@MFW- This is a long-standing issue; You cannot directly modify the texture mapping on Cabinet objects by using the attribute mapping tool on them. (It has been requested previously).

 

The way to do it is to create two identical Renderworks textures for the cabinet wood grain, one of which has been rotated 90 degrees. Then create two new Classes and assign each of those RW textures to their own Class. Depending on which direction the grain of the Cabinet component needs to run, you assign that class.

 

Take a look at this related thread about texture orientation in Door objects.

Early days but I have not seen anything so far that addresses the main issue (for me anyway) for interior designers which is the ability to texture objects correctly. It was disappointing but not unsurprising that the promo video only applied a single colour to the Sub-D object (the big orange/yellow shiny what on earth is it object) as you cannot apply a pattern. Applying the single colour is a cover up for the deficiencies of the tool.

 

A shame but I am hopeful that I missed a lot that is in there for us and its only a matter of time before it comes to the surface. I am certainly looking forward to the new stair tool as the old one was a flipping nightmare (and texturing it was awful)

No changes to that area this year. We wanted to focus more on existing systems that needed improvement this year and held off on introducing too very many new ones. However, this request is still in our sights.
