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.
attached are 3 files that demostrate what is happening when I select a profile to loft and the rails of the Surface and how it changes the profile and how I can get a straight back edge not bowed in like it did to the front
View 4 Replies View RelatedI'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'm trying to make a logo. Circular logo with an inner ring maybe 4 px wide and 15 px inside the rim of the outer circle.
Basically I want a blue circle with a yellow inside ring. What's the best way of doing this? The only thing i can think of is: creating a blue circle marquee, and then another (trying to estimate a new circle size and change the color) that is yellow, and then making another smaller blue circle inside the new one. That's just ugly.
I tried the edit/stroke but that just gave me a stroke around the outer circle; it didn't put a ring inside the circle 15 px down.
Also I tried to contract the original circle by selecting it, then Modify/contract. That's got me a selected ring, inside the circle. Now how in the world do I make that little ring yellow? It just remains selected and I can't seem to find a way to color it.
I'm doing a project for my paper and it would really save me some trouble if i could loft through vba..... the alternative is too boresome....
View 4 Replies View RelatedAutocad 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?

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".

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 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.
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.
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'm currently facing this problem of lofting/elevating the drawing.

not sure why I'm having trouble using the blue "path" layers polyline path to loft the profiles and form the c-clamp.

I have tried convtosolid as well & to no avail.

So I drew a vertical line, set the radius using circunferemces. Then (can't remember how, it was long time ago) I manage to turn them into surfaces (circles, so it's an area).
Now when I loft them, it won't result in a solid. Why?
I am a newbie just start learning how to use AutoCAD in both 2D and 3D.
I have drawn a 3D polyline, and putting two circles with different diameters on both end, trying to loft it and create a horn-shaped like object.
For some reason, AutoCAD keeps complaining the path I selected is not valid, and so I can't do the loft operation. However, I have 'tested' the path with sweep function, and it works.
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.

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 3 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.
