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.
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...
View 2 Replies View RelatedFollowing on from my post regarding a sheet metal component that was unable to create a flat pattern due to creating the component in an assembly; URL....I have found out that it wasn't the in place component that was the problem it seems to be the loft and sweep feature that cause this problem. I have thought about using the extrude feature (as this works) to create the shape and then cutting the ends to get the angles I want but that would be time consuming.
I have set up the sheet metal rule to be 3mm mild steel, any way creating this component and being able to create a flat pattern.
"Join" option in "Loft" command.

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?
View 4 Replies View RelatedI 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).
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.
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 have been using the frame generator quite often and recently the insert frame command is not working properly. I would like to know if there is a fix/patch for this problem or do I have to re-install the program? I am very frustrated with this problem as I do alot of structural design and the insert frame command comes in very very handy.

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?
View 4 Replies View RelatedI'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.
View 9 Replies View RelatedI 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 have created a loft from 4 different sketches. Now I want to make a drawing with the front, side view and the dimensions of the 4 profile sketches from the loft. But I can’t find a way to put the sketches from the part on my paper. It works with copy-paste ;^) but this is not the way I want it (it’ll not change when I change the profiles in the part).

View 9 Replies View RelatedI was wondering if it is possible to make a surface loft go from 1 square section to 2 round sections.
So 1 ingoing section en 2 outgoing sections.
I've attached a simple drawing.
Using the image below, I want to removed the yellow extrusion up to the red circular edge, I assumed split tool would do this.
And I don't require this but i would like to show the splines on the ends to "feather" out to the round like the actual axle does. (this is just for aesthics) I have the extrusion done, But I can't figure out feature is requied to do this, loft?
I have a part that I'm trying to loft using 3d sketches for the rails will this work? Everything is fine till I try to add the rails, As you can see the loft works with out the rails.

Im struggling coming up with a loft or sweep to get the design effect I need. see on the pic how the profile terminates to a point.
View 4 Replies View RelatedI'm trying to produce this loft but the rail I really need it to follow won't produce any results. The other ones on the 3d sketch will work just fine but not the regular sketched one. It seemed to work when I made the rail a straight line but I need it to follow the edge of the surface which is a line, tangent to small r3 arc, tangent to line and connected through projective geometry from the original surface sketch.

View 4 Replies View RelatedI want to create a solid using VB and loft definition.
I creat each time different planes that have a constant distance in x dimension and a steady rotation each time φ (deg).
On each each plane i sketch the same profile and that is happened for 360 deg.
The problem is that Loft is not made because a line of the profile must follow a line tragectory and all other points must follow a circular tragectory. Also, there is a problem from 180 deg to 360 because there is intersection of profiles.
The result must be a solid similar to snail shell but all the same solid, as a cylindar whith a half sphere in the bottom.
In the attached sample file if you edit the sketch in the first surface feature and change the dimension of 600 to 700, both the patch and loft features fail. It seems to be the curved edge that is the problem in both cases.
I cant see anything wrong with either way of modelling this so assume its a bug.This causes other problems in my real model with parts that reference these types of surfaces falling apart further down stream and is wasting heaps of $$$.
I made this part, which is a loft consisting of five symmetric squares. I plan on laser cutting each side, which would be exactly the same.
I can't seem to figure out how to make a flat projection of one of the sides. I have tried in sheet metal, but I don't use that feature in my line of work.
I am trying to loft a port shape for a project. I have been able to loft pretty much the same thing when part of a larger model but this time around it keeps giving me an error.
In the past i will loft the whole part then remove the inner portion to get the port.
I work at a car seat company, and we are just now, starting to draw in Inventor. I have problems drawing the seat belt. Here is my first try:
I have tampered with this one! From this angle it looks ok, but it isn't right. I have tried using Loft and Sweep, but with no good results! The seat belt is static in the shown position, but should be able to adjust onto another seat.
I am having to model a spiral slide in sections, and the top piece has this weird angled lip where the opening distorts. Im simply trying to take the face of the extruded part (in three sections) and loft it to the sketch on a different plane. And use the sketched curve as the centerline.
