Basically I am following a tutorial which says that when you create a loft from a path and two shapes, the loft should still be linked to the shapes, so if you resize one, the loft would change, but that is not happening for me. I am using 2014 so I don't know if this feature has changed, or if you access it in a different way?

I have 3 scientific waveforms, made into splines , from X,Y and Z data. Basically 3 long wiggly lines.
I wish to visualise the data by modulating a spheres surface in 3 dimensions so that the X data creates wave on the surface of the sphere running along the x-axis , the Y data along the Y axis and the Z along the Z axis. All the data (splines) will interfere and modulate with each other across the surface.
I have spent a couple of days looking at nurbs and lofting but cannot even get close to this. They all only allow splines in 2 dimensions to interact and nurbs cannot cope with the data volume anyway.
ps i can obviously extrude the 1d data or lathe the data but each only makes 1 or 2d surface interaction. The attatched pic is each one of the data splines made into a sphere using a 180 bend and lathe. This isnt exactly how id ideally have it. I need all three joined into one shape.
I have spent some time over the last few days attempting to create a boat hull by lofting sections along a line representing the center line of the hull, but I'm not having much luck. The shape that is created appears to be rotated some weird way, and I just can't seem to get a handle on what is going on. The section splines were created in the Front view, the path was created in the Top view. The section shapes were then placed in the Left view to correspond to their location along the hull.
My question is this: where can I find a tutorial that deals with boat hulls and lofting specifically, or failing that.
It's new to me the loft compound object, and I found it a little cumbersome.Provided the shape objects have the same amount of vertices, the loft should do its business, is it?
View 6 Replies View RelatedI often have to import shapes via illustrator export/import. Then I have to scale all the shapes up to real world 1:1 size.
I typically just grab all objects and use the SCALE tool...but I hear that is actually the WRONG approach?
So I tried scaling all the objects at a sub-object level. i.e. select ONE object, yellow highlight vertex, segment or spline... then scale up.
Is it possible to select multiple/all my shapes and scale up this way? When I select all of them, my modifier stack obviously disables and cannot select via sub-object (vertex, segment or spline level).
I tried grouping. modifier stack disables still. Do I have to ATTACH each one to another (multiple I guess via list?) and then scale all them via SEGMENT level?
Is there a easier/faster way to do lots of objects imported like this...or is this the way to do it?

Typically a door hadle lever comprising initially circular geometry at the rose (fixing point) with round bar (x place)geometry up to and around the initial lever bend. Then the lever elongates in section and curves along a y plane and possible twists along its sweep path. Ive tried mass and create solid using a path with worlplane aligned geometry with fail every time, Also tried in face based generic. The problem is a bit abstract in that only trying to take an image in a manufacturers catalog of a manufactured component and recreate the design phase. Can this be done (sucessfully) simply.

Hosting circles and then curved profiles is not working for me - cant get uniformity in the way the circles sweep into the curved parts

Im trying to make a 3d model of a site in AutoCAD and it seems lofting between some contours is impossible, this is driving me insane, first it told me there was a U and V derivative problem so i loft the surfaces that i could but now there is a gap where it refuses to loft and i cannot create a surface in that gap using network or blend or pach.
View 3 Replies View RelatedI have to do a lot of lofting to create 3D shapes. The more the 2D sections are complicated, the more times takes for AutoCad to find a solution (even in a powerful computer). Beside that, I use Guide splines to create the exact shape I want. For this I have to wait two times, first Autocad find its own solution, then the solution with my Guides. Is there a way to make AutoCad loft by default with Guides, such that it doesn't ask for Guides after the initial loft, but immediately at the beginning.

I'm trying to make a simple race track for my uni project. I've created the track's path using lines and arcs, and attached them all together into one single path.
[URL]
I'm then trying to extrude the track geometry (a simple rectangle) along the path of the track (see the bottom image).
I'm following a tutorial that says to select the line, then under compound objects select loft. Then under creation method I should chose "Get shape" and select the rectangle, however I'm unable to click on "get shape", the option is greyed out.

I'm trying to loft a base for a light fixture. It's narrowest at the top and bottom, and its widest point is in the middle. classic design.
Can I upload a pdf? I assume if it's available to everyone via a search engine, wouldn't it be ok to upload it? Any thoughts?
I digress. I'm trying to look at the circles from the side, so they form horizontal lines. I thought they'd be easier to offset a distance to.
I tried changing my views around to achieve that effect, but to no avail. UCS is World view. Or View.
One of the images in the .pdf, is of the appearance I'm after in a front view. So that way, I could do an offset distance of one inch, but as things stand now, that wouldn't work either.
It wouldn't work in this view projection, I think was what the wording was; or close to it.
The only view I was able to do any offsets in was the Top view IIRC, but that just gave me a bunch of concentric circles with no height. At least they were offset.
I want to loft the surface, made of polylines.The problem is that, when I select all the splines, and then do Draw-> Modeling -> Loft then I chose the "Cross-section only", this what kind of message I get in command box:

Basically we are trying to make a 3D plate (in this case a 2" thick piece of steel) and have a 3D hollow shape inside. Its split into Top and bottom, as shown as the below picture.
top View (plate 1).jpg
I have tried the loft command (which I just learned off within the past hour or so) and it indeed works. But I wish to use its as the opposite, where the middle is hollow and the rest is a solid object.
Side View (plate 1).jpg
I have tried the loft command (which I just learned off within the past hour or so) and it indeed works. But for the life of me does not know how to get it as one big object with the middle shape hollow. Am i missing a step or is it another command completely?
Also, once the object has been created, I want to split the object on its X axis mulitple times, almost like an exploded view. Each split will have its own set of top and bottom orifices which will represent multiple plates.
Is there a way to do that? Also is there a way to gain and separate the top and bottoms of these newly split plates?
Here is the drawing file as well to work on -> 3D-MK1.dwg
In previous autocad version that supported Lofting, i was always able to create a solid loft.
With 2013 the loft command seems to divide its abilities depending on what type of profiles are selected.
When selecting a closed polyline profile, loft produces a solid. Works fine.
When selecting a region or solid face loft produces only a surface.
The work i am trying to do at the moment involves irregular sections and/created from existing solids.
I could trace the profile and make a polyline, but each profile contains an ellipse, and you cant trace an ellipse.
Where i used to be able to select the ends of the existing solids and create a solid loft,
I now have to produce a section twice (gives you a region), loft the regions, convert the regions to surfaces (because the produced surface doesn't have and faces), union the surface and then convert to solids
Instead of 1 command there are now 6.
I tried turning of the assiciativity (surfaceassociativity 0) hoping that it had some sort of influence but to no avail.
There was no issue with 2010 and 2012 and i have just installed all 2013 products.

I am working on creating a male mold for a canoe. I first designed the cross sections for the canoe and then began converting them to the mold cross sections. When I try to loft the cross sections I have converted so far, they all loft as I intended until I get to the rear of the canoe (sketch 8). The issue typically arises in gunwale section (the part that appears to be a notch in the sides). Everytime I loft, one of the gunwales splits/twists in an undesired fashion (in the image below the right gunwale is incorrectly twisted).
I do not understand why this is happening for a few reason:
1. The canoe cross sections lofted as planned, and I only added simple boxy shapes to those cross sections.
2. Each cross section is symmetrical (or at least from what I can tell they are).
3. The cross sections that are lofting improperly all have the same number of segments and are in very similar shapes.
I have attached the file of the cross sections and another file of an improper loft.
Coming from Sketch up to real big boy tools. I watched the tutorial videos and tried poking around a bit for this specific answer but came up a bit short.
What I'm trying to do is loft a face to a point. Easy enough. I've got my point established on an offset work plane, and I can just loft to that, however, I get nothing but straight lines. (First attachment)
An example of the ideal outcome in SketchUp is the second attachment.
I'm having the most difficulty trying to draw the curves along which I want the face to be lofted because, even as I sketch along my 2D plane, I can't snap the endpoints of my arcs to the endpoints of the face (or the point to which they'll all connect).
If you can create a solid by lofting between two section, in this case they are 3d polylines, along a given path. The path is at the top of the sections. Using the loft command I have to key in the PO ( point ) option several times to get the path option to show then when I select the path it gets treated as another section. See attached.

Now that I´m done, I realised there is a problem... how can I color in the drawing, if the lines themselves make up the shape? Essentially, I´m left with blank spaces in between all the lines instead of solid individual shapes that can be colored in.
What can I do? I´m so desperate I´m thinking of creating a gazillion individual shapes with the colors, and slapping them underneath the lines to "improv" a fill. But that will take waay too long, so is there an easier way?
If I could "invert" the shape I have now, so that the blank spaces become individual shapes, and the lines become blank spaces.
