Maya Modeling :: How To Convert Parametric Models Created In CAD
Jul 13, 2012
I often create animations for technology companies, and they give me models that were created in programs like alias, rhino, AutoCAD, or solid works. They export for me in IGES, or STEP, and the models, while amazingly intricate, are too much for Maya on my 24GB RAM 12-core machine to take. They take upwards of 20 minutes just to open.
I want to convert these to ploys and generally make them easier to work with. What are my options for making these manageable, and still look good when they render. The flat edges and services are fairly easy to convert, it's the rounded bevels that don't look so good if I convert everything to Polys all at once. And there are usually hundreds of curved surfaces to convert, so doing them one at a time is far too cumbersome to be effective.
Also, how would I go about taking surfaces for objects in joining them together to create a complete object made of Polys? For example, a small part may be made of 35 difference parametric surfaces in solid works, and exports as that in IGES, so when I imported into Maya, it really should be just one object made of Polys.
need to convert parametric cad objects to poly to make them manageable and to make renders faster.
I am stumbling through the lessons and am stuck on Lesson #1.For those who do not know, it is to model a helmet similar to a dirt bike helmet. I have created a smoothed poly, removed much of it to create the top portion of the helmet (or cap).
I have created a poly shape using the Mesh >> Create Poly command. I have extruded said poly 3 times to shape the front facial guard.
The next step tells me to use the bridge border edges command. My problem is only my "cap" is showing a border edge. The facial shield poly has no border and I cant figure out why?
I have tried Display >> Polygons >> Border Edges and it doesn't make a difference on the facial shield.how do i view the border edges on said poly?
I have traced out this piece of geometry using CV curve and then used loft to convert the Curves into actual geometry. I need to have one solid piece of geometry to project an image onto, how can I convert this to one solid piece? I have attached my .mb file.horro_chair.mb.zip
When i try to convert Poly to Subdiv I get this message in script editor:
polyToSubdiv -ap 0 -ch off -aut on -maxPolyCount 1500 -maxEdgesPerVert 32 |polySurface8|polySurfaceShape9; // Warning: Nothing is selected. Select objects or components to delete. // // Error: Command polyToSubdiv failed. Open Script Editor for details. //
It is strange, because I fixed all non-quad faces. I also tried all cleaning options with no success.
Maya 2012 64bit, Win7..I can not convert a polygonal model to subdivision with proxy (command failed),do not see error description in the script editor. What typical problems of convertation (poly->subdiv) do you know ?
I have some particles that i've used the Instancer (Replacement) on to turn into a mesh that I have modeled and place throughout the scene. Now I want to convert the instanced particles to regular geometry.
I'd like a more intuitive way to set up UV maps in Maya. It seems to me that there should be a process similar to using low polygon models as wrap deformers. Basically I figure that the low polygon would act as a projection wrap allowing for less UVs to adjust but enabling a very good flow of the texture map around any polygon, subdivision, and NURBS model of any complexity. Is there such a thing? If not, is there a way I can convert a wrap deformer to be a UV projection object?
I have teached myself working with autocad version 2004 so maybe its not the right way of drawing but I draw 3D objects using solids!
In the past I could take or put dimensions on this solids to print and pass on to colleagues but on our new 2013 version I seem incapable of doing this I can not select a point on a solid and continuously get the message invalid point!!!
working in 3D modeling space using parametric linear! what am I doing wrong? or is it an setting that I need to change?
I was importing a model with 3 materials / textures. And the imported model's fully textured with lighter color textures than the original ones.
And the problem started when I exported the model as .DAE and import it in to Unity, the texture slot (or material slots, I don't know how to call it) was 1 instead of 3 with the original model
And this is the original one Were the animated model's texture maps I imported get merged into 1?
Also, I added an independence sword model, is it's texture map get merge into to big 1 above?
I downloaded some 3ds models, but I have problem with some of them. Well, I see all objects in the project but when I render, the render box is totally black.
i've modeled a character or two from scratch in max. (nothing spectacular) I also used a character pack a few years ago. I was wanting some info on the best way to model a new character. I would like opinions on zbrush, poser, etc. Something that is very compatible with max.
What is the process that you take when creating a character. Don't feel the neeed to write a book I get the basics. Been out of the game for a while, but very glad to be back. Been playing around with fumefx, houdinni ocean, and ivy lately.
I'm familiar with blend shapes within a given model, but I'm wondering if there's some way to blend SEPARATE models so that one blends into another, perhaps by assigning points manually or something of the sort.
I study vertebrate development. I will be creating a bunch of 3D files based on confocal microscope data at different developmental time points, and I'd like to make a 3D model in Maya that blends these various models chronologically.
I have a demo reel and I want to list my poly count next to my models. maya calculates triangles and faces(which to me are polys also). so should I say poly count: (#of triangles) or poly count: (#of faces). which is the employer more interested in (specifically in the gaming world).
I have a problem when I am modeling my character or rather the character from the animation academy. I have created an NURBS sphere and I want to adjust it to the arm, so I go to the component mode add some isosparms and then it happens!!! I can´t move any vertexes... but in the object mode I can move the hole object.
When I go to edit mesh on a brand new hedra and take two points and scale them, the sides are uneven, one side isn't scaling properly. It looks to be the one with the square edge. Here's a video.
We are looking for a workflow example of developing casting models into machining models.
Typically our castings are made from different materials (Fig-1) and then machining (Fig-2) are created from these castings.
Is creating the casting as an iPart (with different materials) and then deriving the machining from the casting the proper method?
Doing it this way seems to force us into making a machining for each casting material instead of just one machining that is an iPart. How should this be set-up for BOM purposes and for use with Vault (Base Version)?
I extract a displacement map from Mudbox 2012 that has just a simple sphere. Then in Maya 2012, I create a file node and try to load the displacement map. Maya crash.....
I have created a script to convert in a batch, about 2000 images, the problem is that gimp-file-save ignores image settings and uses its own defaults, so the image that has 6 layers, after being scaled, has only one layer!
as you can see, this is a generic script, I would like to avoid using the specific dds load/save because of increased complexity and for being specific to dds...
is it possible to set some format based on the original file? I could use the dds file save, parsing output from "identify -verbose filename" (imagemagick), but that will be a lot of trouble...
I have a bunch of curves that is going to drive nhair. However I'd like to use the "soft modification tool" to do further adjustments to the curves. But I'd want to pin the root of the curves so it doesn't fly off the head when I use soft modification. Is there any way I can lock or pin the root CV of the curve? (its a cubic nurbs curve)
I have a file that was created in the online trial version of Corel Draw. How can I open it in my full version of X5? I'm getting an "invalid format" error message.
I wish to create a testing surface for simulation from a DSM height data (under a college assignment). I downloaded a height data from [URL]........ in a .dwg file format and want to import in on maya and create a surface out of it.
Now the only thing I want to do is to cut out this:
[URL]........
I used the Extrude tool just for visualization. The problem is, working with booleans apparently doesn't work for such objects, it works for freshly created clean polygons, but not for this one, when I try to use "Boolean difference" both objects disappear.
Extruding doesn't work because the faces are still there and I cannot delete them for whatever reason:
[URL].........
My cursor is pointing on the little face, but both are being highlighted. Making a hole through the the "Make a hole" function doesn't work because it only deletes faces as it seems.
My model loses lambert on only certain faces every so often. Might be related to clicking on camera or trying to extrude certain edges. I want to delete the camera but this happens to the model every time i touch the camera. I can't reapply the lambert by pressing 6 or assigning new material. if you know what's happening.
I am looking for the same function in Maya that I use alot in 3DS. In 3DS, you can "Merge" (import) models from another scene (file) into your current one. It allows you to pick a single model from the imported scene to be imported into the current scene.
I know Maya has the import function but it seems to import all the objects. I just want to import a particular model.
Is this possible in maya?
3DS Max 6 to 2009, Maya 2010 NVIDIA Quadro 1700, Quad Core 2.67GHz, 4Gb RAM [URL]....
Here is what I've tried so far in creating the pupil of the eyeball:
1. Right click - select isoparm - attempt to select. 2. Right click - select Surface Point - attempt to select. 3. Left clicking 4. Holding shift (and other keys) - attempt to select 5. Right clicking 6. Middle clicking 7. Marqueeing
When I right click - select surface point, I get something that looks like a selection, but it also has an isoparm dotted line.... when I attempt to DETACH I get an error.
I am attempting to import 3d models from a software called Daz studio into Maya. The models enter motionbuilder and 3ds Max with no problem. When I import them into Maya they come in as wireframe. I have been unable to take the wireframe off of the model. The file format I am using is FBX. wHEN I RENDER an image of the model i am able to see it in it's realistic form-but when i attempt to see it in the viewport it is wireframe.
Say I have a car engine that I created. to make it easier on myself I made it out of a bunch of separate pieces. then at the end I combined them into one. somewhere down the line I'll want to animate the pieces separately, but until then I dont want all that inner geometry rendering because it takes up unnecessary render time. is there a function in maya where I can delete all invisible mesh geometry? so then any faces inside the outermost shell will be deleted.
