3ds Max Modeling :: Acad Loft Command To Model Veins
Jan 7, 2011
I'm going to be creating a 3d visualization for an existing network of gold mining tunnels and ore veins. What I have are scans of 2d hand drawn pages showing mining tunnels and ore veins. There are a couple hundred of these, each representing a 100' thick slice which get progreessively deeper. My intent is to trace these in autocad and stack them up, create solids, import them into 3ds max. One issue is that the ore veins are in some cases continuous from level to level so I'm thinking of using polylines and the loft command to connect the veins between levels.
how to model this efficiently so the import into 3ds max goes smoothly. Or is there an easier way than the acad loft command to model the veins within 3DSMax?

I am trying to loft 4 circles onto a straight path it seems as if they are turning somewhere in the middle, and the shape ends up looking like several 8:s stacked on top of each other instead of the cone-like shape I'm after.
I've tried aligning the first vertices with the "make first" command, but it didn't work. If I go to subobject level of the lofted object and choose Shape > Compare (as I read in some thread I should..), the pop-up window shows nothing (blank, with the pointer in the middle, doesn't matter how much I zoom).

I am having multiple problems creating a loft. Firstly, it seems as if the "loft" command remembers and uses history of the objects to be lofted, which in my case meant that instead of lofting the scaled down (correct) version of a shape, it insisted on lofting the former, out-of-scale version. It would be great to know if there's a more conveniant workaround to this than redrawing the shapes (as I ended up doing).
Secondly - and this is where I'm stuck now - 3ds will not let me do a loft with the new, redrawn shapes. The loft accepts two of the shapes, but will not let me select the remaining three, claiming that "the shape has a different number of curves than others in the Loft". My question is thus: What should I do to be able to see and edit the number of curves in the shape, so that my Loft will be valid?

I recently upgraded to Civil 3D 2011 from C3D2010. I have used the same ACAD.PGP file for years that includes the shortcut C for the COPY command. Up until C3D2011 this would always allow me to copy an entity multiple times, (the default when COPYMODE is set to 0).
I am running C3D2011 64bit on WIN 7 64bit OS. It happens with other commands too that use a dialog box normally, i.e. INSERT - it only brings up the command line version of it.

I am trying to loft a hull of a yacht, but I am not having much success with regards to getting it neat!
I have attached a screen capture and you will notice that the isopalms are not exactly neat, they are wavy and all over the place.
Is there a way to neaten these up so that they are fairly level ?

I'm trying to create a "wipeoutish" track using splines. In fact, the track itself is generated by a tool and I want to use it in 3dsMax to create the environment.
So i'm importing the spline into 3dsMax, create a template spline and use "Loft" or "Sweep" to extrude the model along the track. But whereas everything works if my track is perfectly planar, I get some crazy stuffs if there's even the slightest change in the Z axis.
I've tried disabling Contour (then the track is horizontal but there are problems at each turns) and Banking but I can't seem to be able to get a perfectly horizontal track using this way.
Is there a way to force the normal of the generated Track to be vertical ? (get the green track over the spline used by the blue track ...)

I'm making a short oval race track. I'm lofting along an oval shaped path and can get the track width consistant all the way round - but my issue is that I want the bends to have more width than the straights.
i've seen examples of lofts having more than 1 shape along them (tubes turning into cubes at certain points etc), but I just lofted my path to a line as the track only needs to be a flat 2 dimensional surface.The scale deformations allows for some change of width, but doesn't seem to have much accuracy.
The black line is the path, grey area is the loft produced, blue area is an example of how I want the track area to be.I'm using 3dsmax v5.

I'm building a test track to use on a driving simulator.I'm trying to apply banking to the corners. The track's path is a loft with it's path defined as a line, and the loft shape is a rectangle to represent the cross section of the track. I'm trying to apply banking to the corner by using a different shape part way along the loft... however, the result is that the track twists the wrong way so that the top of the track becomes the side and vice versa.

I am following the U-Tube exercise called "Emergency Light (Cabinet) volume 1". I am at time stamp 1 hour 26 minutes, exactly.
In the video they use a Loft command in order to cut a shape out of two sketches numbered 10 & 11. I have been copying exactly and am having difficulty at this stage of the model.
Is there any reason why I am managing to use the Loft command earlier perfectly but not at this point.

There is a major bug with CorelCAD LOFT command - when used with 3D polyline objects, it fails and errors out with the following error:
Specify cross-sections in lofting order»1 found, 2 totalSpecify cross-sections in lofting order»Selected cross-section is not a valid type.
The workaround is to set the CCS to the plane of the 3D polyline object and then use 2D polylines to recreate it, move the 2D version, delete the 3D version, Align the 2D version with where the 3D version came from and then repeat the LOFT command.
Has been logged with Graebert under ticket: #12458
To repeat the error, see the test file. There are two radially aligned triangles in each set. The set on the left are 3D polyline. The set on the right are 2D polyline. Attempting to loft the set on the left will cause the error.
Both large and small triangles are respectively co-planar.

How can i interact with the source code of LOFT command.Especially, I'd like to inform me, about the method that Loft commad uses in order to draw a solid. I suppose that the two sketches I want to intersect, are close enough, thus the programm, can't generate the geometry...

I am trying to LOFT multiple ellipse shapes along a spline path to create a door handle. But as soon as I choose 1 section, MAX creates the shape. I cannot figure out how to create the shape with multiple cross sections. I have attached a screen shot and a pic of the door handle I want to create.

I have a bunch of points that I am trying to turn into a solid object. I am doing this by using the 3D poly command and then LOFT, UNION and CONVTOSOLID. this has previously worked well, but this time when I use the LOFT command it does not produce a 'closed' surface, but rather a grid like surface which wont convert to a solid. Are there different settings for the LOFT command, and if so, How do I change them to produce a closed surface?

I have some trouble removing veins from eyes. I have tried clone stamp but it messes the tonality if the eye. I have tried hue / saturation but it leaves the veins black. Is there no way to directly go from black veins to white veins that have a value equal to their immediate sorroundings?

So I have a problem opening this drawing that i have worked on for quite a while now and all of a sudden this morning when i tried to open it i got the following message:
"This DWG file was saved by an application that was not developed or licensed by Autodesk. What do you want to do?"When I continue to open the drawing some stuff is missing from the drawing?I am using Acad LT 2012 and this drawing was working fine until now.

I'm trying to cut up a model into components. I'm using QuickSlice but it doesn't seem to be functioning the way it's supposed to. It's a building with straight edges so it should be really straightforward. In perspective view I select an edge which is just a single edge running between two vertices.I then press QuickSlice. Then with snap to vertex on, I select both vertices in turn but the slice runs off right around the back of my model in a seemingly random way. I don't get it- I'm following the instructions in the description.

I have a bunch of drawings for which I have to reload the linetypes (they have to be redefined, for example pneumatic line has a new definition but the drawing has an older one). Is there a way other than rename the old linetypes, then load the newer version, then iterate through all objects and change the linetype to the newer version?

I have a Revit model of rework to an existing building. I am working from Revit Architecture 2011. When I export this model to AutoCAD, I am getting inconsistancies of my new work walls. Some of my new walls are coming in ACAD with solid hatch, others have no hatch at all. At this point I do not care if all my new walls have any hatch or not, as long as the heavier lineweights come through to make them different from existing walls and that they are all consistant. I've been searching on this for a few days now and have come up with nothing.

At this present time I would consider myself a high end beginner at 3ds max.
I am currently trying to model a mech and have been trying to smooth it. I have made progress but I don't know where to take the geometry from here. There are numerous smoothing errors in the model and I understand why they are happening, I just don’t know the right way to fix them. You will understand what I mean if you have a look at the model (I've attached it so you can download it).
For example, in the first image you can see an error, if I extended the edges this may get rid of it, but then I get the result in the second image, and it doesn't look right .

I want to model a hollow stone shaped (see images attached) object in 3D max that will be 3D printed. The stone shape has to have a separate top and bottom so that I can embed electronics in it afterwards. My problem is I am finding it difficult to create a lip that will enable the top & bottom to securely fit into one another, so that when someone picks it up it will not fall apart. I was thinking of using a system like the attached image Lip_Profile.gif. I have no problem modelling something like this on a regular box/sphere using a lathe, however I can't find a technique to model this on irregular objects. Any technique that would enable me to model such a fitted lid?

How do i add a symmetry to my box model in 3dsmax where when i move a vertex,edge,polygon etc on one side the same thing happens on the other side instantly. I've seen this done in zbrush and xsi wondering how i can do this on 3dsmax. I've used the symmetry modifier but the other side does not move when i edit the other.

I need to model a cloth in Maya 2012 as a part of a college assignment. I have attached a jpeg of my pre-production artwork, in it you can see the yellow cloth placed on two wooden planks. At the moment I am modelling the cloth by adjusting the vertices, but find it to be a bit tedious. Is there any other way for me get effective results. Since I am a beginner I would like to know the the different ways a little in detail.

I trying to model a mountain whith a spiky look. what its the best method to do it?
things that did not work:
1) Use a displacment map. there is not satellite images in the web. (good quality images)
2) Use Z-Brush. I really dont have time to learn another program.
Actually im trying poly-model technique, starting whit a plane, whith the image as a background, and guessing the perspective.
I'm in the right way?.

I'm using max 2011
I have a model which was originally a SAT file, it was just an extruded profile in the CAD package. When originally imported the part was fine, was selectable etc, but now for some reason this part is non-selectable, won't disappear when you do "hide all" etc but still renders and will still accept material types applied to it ?
