AutoCAD Inventor :: Loft Between 3D And Normal Sketch?
Nov 6, 2011
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.
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).
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.
Im trying to create a shape like the attached image using sheet metal loft from one sketch to the second sketch. No problem doing that but i want to extend the neck on the small end 1 inch like the attached image.
Currently the product is produced using 4 panels brazed together. I want to create the product with 2 bent panels 90 degrees that are split apart from the loft.
Not sure if this even possible in the real world sheet metal house to develop the flat pattern.
Is there any way to stop the flipping of the solid/sketch view from iso to normal?
its annoying to make changes to a sketch and constantly have to re orient the part after finishing a sketch, I dont want the solid model to return to iso view after sketching, is there a setting for this?
I would like to be able to offset a 3D Sketch in a direction normal to a plane. In the attached image, I have drawn in an orange color the direction I would like the 3DSketch to offset.The white line is where the new sketch would be.
The yellow surface is the 3dsketch extend to a plane
There might be some tools in Inventor that will do what I am trying, but I have not found it yet. I have tried extend surface, but that will not take it the direction I want.
I've created a shared sketch and have used it with various features. Sometime those features are suppressed. The model works fine but the shared sketch generates a sketch doctor error because the feature that created it has been suppressed. Is there anyway to make the sketch suppressed so it doesn't trigger a sketch doctor error? Inventor 2013
How do I duplicate the 2D line work from a part level sketch into a drawing level (overlay) sketch?
I started a simple 2D piping system diagram sketch by opening a new part file and using a sketch to stick draw the system schematic including some annotations. Then I opened a new drawing file and made a base view of the part file to bring a view of the original sketch into the drawing.
I realize now that it would have been much easier to have created the schematic directly in a 2D sketch at the drawing level, which would have made editing the annotations much easier at the drawing level, and there is really no need for the part file to exist. I have no intention of creating a 3D model or "real" part in the .ipt file, was just using it as a jumping off point to sketch.
I was thinking that I could correct my error in judgment by just copying the sketch and pasting it into a new sketch on the drawing, but it doesn't want to work that way. I have tried copying both the whole sketch at the browser level, and the entire sketch contents (all of the lines and annotations) from the opened part sketch, but when I attempt to paste either of those into the drawing, paste does not seem to be an option. I'd rather not have to draw the whole thing again, as in typical fashion, my once simple sketch has grown in proportion and complexity from its simple beginning.
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 having trouble with constaints, I'd like to constrain my sketch to a point in another sketch on a different plane. Is this posible in Inventor? If so how? If Inventor works differently how would you get a points in one sketch to be linked to points another?
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.
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 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 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.
I'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.
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
I 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.
