3ds Max Modeling :: Loft Command Aligning
Jan 31, 2011
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'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 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 am having some difficulty getting objects to exactly align to another. When I zoom in as much as I can I see that the two objects edges are not exactly aligned to each other on one axis despite having the same co-ordinate values. I am working in meters unit value. I have tried going to millimeter unit setup but I still have the object aligning issue using what seems to be the finest level of movement - 3 millimeters per movement action.

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.

Is there some way to make the Scale Tool stop when multiple selected verts or edges are aligned, like in Max? I've noticed that you can overshoot when trying to align this way. I suppose there is always snapping to grid..

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 created the attached wheel drawing using the Revolve command.
You will see one cylinder solid thru the wheel on the attached drawing file.
I am trying to use the Subtract command to remove a hole space thru the wheel. Can't get that to work.

Autocad used to perform the LOFT command partially in the COMMAND LINE and additional properties could be setted in the DIALOGUE BOX.
I used to draw my lofted elements :
1. Pick sections in order
2. Following Guide, Path,...
3. Dialogue box ( sections smooth fit, ruled, normal to,...)
4. Volume was drawn.
Nowdays it's a bit more extended but in step 2 when u pick a path the volume is drawn immediately and I can't append additional properties like in step 3.
Filedia is on 1
How do I get to the Loft dialogue box ?

I need to shell out a Loft in the attached IV 2012 part file.The Loft i tried also as a new solid but the shell also cuts into the cylinder ( revolution 1 ) . I only want the 2 sides and bottom of the Loft to be Shelled, not the cylinder. What do i need to change to get the shell to work?

I'm constructing a simple test track for my university project, and I have managed to get the geometry of the track all sorted. I'm struggling to assign a bitmap image of a 4 lane road surface to the track. When I assign the material all I get is a grey surface with no lane markings. I figured the size may be wrong, but I have tried adjusting the size settings in the co-ordinates roll out in the material editor, with no luck.

I want to loft two rectangles using arc as a path , but i cant , 1st i cant draw the arc in 3d so i draw it in "Front" view , then i cant loft the rectangles using that arc as an path -"The selected entities are not valid" , maybe because i draw the arc in "Front"(bottom left), but i cant draw it in 3d?!! Here it is some screen shot:

I'm trying to loft a profile between 3 circles and i have created 2 2d spline guides to loft through (see picture).
I get an error when i select the two splines as guides which says
"Modeling Operation Error:
The guide is not G1 between first and last sections. The selected entities are not valid"
The guides are definitely touching the profile edges so I'm not sure what the problem is.

As CAD administrator at my company, which is in the process of implementing Inventor/Vault, I am quite sold on the Layout Modeling/Multi-body part modeling functionality that Inventor supports. Among other things I believe there is a large payoff in assembly stability and simplicity. However, this workflow is very different from the conventional methods of modeling individual parts and manually constraining assemblies. URLs....

I'm loft retarded. What I did here was loft to a tangent work plane, then did a sketch on the top surface and extruded the shape that I want. There has to be a better & easier way.

I have a cylinder on top of a curved surface; I want to make the cylinder land adaptively to the surface, so I projected the circular face of the cylinder in the surface, which ended up being a 3D sketch. I tried to loft a solid between both curves, but it always gives me errors. Some examples are:The attempted operation did not produce a meaningful result. Try with different inputs.Multiple disjoint loops found in a profile section.
I have had success when trying to do the same thing with curved surfaces in two dimensions only (e.g. extruding a 2D curve), but I think the error is produced since the curved face I am trying to use belongs to an elipsiod.

Okay I've been building random things to teach myself how to use Inventor and right now I'm stuck on a rim I'm creating. My question is.. is there a way to copy and paste a lofted item since there are three parts to it (2 planes and 1 guide) because I need 4 more spokes and if I copy the loft it copies all three parts seperately. Then when I paste and orientate the small end of the loft to the plane I want it tells me "Unsatisfied Geometric Inputs".

I am having trouble trying to get the Loft-1 to run the same shape as Revolution-2 .Picture 1-1 shows how Loft-1 is slightly off centre to Revolution-2 at the top .could i model the Loft-1 and Revolution-2 using different tools in one command making it a smooth shape. Another problem i have is how do i make Revolution-2 at the end terminate into Revolution-1 smoothly.I tried using Loft but it kept getting fail message.Picture 1-2 shows where to terminate the end into the Revolution-1 body.

I have a simple Loft compound object with a single straight line using 5 instances of a shape, all rotating by a certain degree. I now need to animate the rotation of one of the shapes however when I try this, no keys are created when I rotate it.
Is this only possible by collapsing the loft and editing the vertices?
