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.

Attached is an Inventor 2012 part file. I am trying to perform a surface loft with multiple sketches and rails. Each time I try to perform this operation I get the following error:
Error: The attempted loft operation had problems with the specified rail curve not intersecting one or more sections. Try repairing the rail curve so that it intersects all the sections.
I have corrected this issue as much as I know how by project the rails onto each sketchs workplane and then using the projected points to constrain the sketch. It is not working.
It is very difficult to explain, but I have attached the part file. It was created from Autodesk Inventor 2012.
1. How do i place holes in the 2 rails at center height..the holes placed in the rails so as to place bolt through both rails...i do not know how to place these holes around the curved rails
2. Can these rails be made using Sheet Metal tools.I would like to unfold if possible...not much experience in sheet Metal
Also, I'm having a hard time completely constraining copy 2D sketches. What Inventor requires to constrain a 2D sketch?
View 9 Replies View RelatedWhat instances is it necessary to combine 3d sketches with 2d sketches, I have used this combination a few times where I have to build rectangular frames then apply frame generator to the sketches to construct the frame members. I was told when I originally had training on Inventor 2013 that 3d sketches should be avoided where possible.

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 have the following (somewhat philosophical) question: what is the concept of assembly sketches? As far as I can see (and what I use it for) is the following: an element of my design can be constructed from several parts, which are first machined with some margins, interfaces for welding, etc. Then they are mounted/welded/brazed together, and the final piece is constructed by post-machining the mounted (welded/brased/etc) assembly. Assembly sketches drive these features.
When I first got in contact with assembly sketches, I believed they can be used to positioning parts in the assembly: create a sketch, very easily and quickly draw lines/points/etc which serve as anchor points for the parts, and then constrain the parts to these lines/points/etc. But this does not work - whereas I would find it sometimes useful.
I've been making a model plane model in inventor 2012 from imported IGES geometry, and Realised that my sketches were not assigned to any part (and thus can't be lofted). Is there any way of moving the sketches to the newly created part without redrawing everything? I've tried dragging and dropping because it seemed to make sense, but alas, that had no success.

Quite often we cretae schematic line drawings for clients approval before creating full 3D models for production. Is it possible to achieve this in Inventor and maybe go on to use the sketches as a master filoe to drive the design? Or should I continue to get approval based in AutoCAD and then switch over to Inventor?

I need to modify a sketch and to create an alternate sketch (suppress/unsuppress) but get an error message when i try to edit the sketch.

I have created a frame using the frame generator that I need to document. It is created using about 5 sketches. The sketches are part of their own .ipt file. Now I would like to document the frame but cannot figure out how to do it. I have tried creating sections of the frame but I cannot snap to points of interest on the frame, such as where two pipes meet, when dimensioning. How do I document the sketches?
View 9 Replies View Related I'm trying to employ a technique that I've used with SolidWorks. I'm working on a project with several engineers doing design work on a large assembly. The way I've seen this handled in a SolidWorks shop is to create a master assembly with sketches on the principal planes that define envelopes for sub assemblies, interface dimensions, and so on. Each engineer can have the master assembly in their sub assembly, as a guide. Where I've used this before, it has worked with integrating the sub assemblies later on.
Here's the complication: There are several different "families" of the product that require different dimensions on the master sketches. What I had hoped to do in Inventor was use view representations or level of detail representation to control the visibility of these "families" of master sketches. When an engineer includes the master assembly in his sub assembly he could then easily turn on the "family" he wants to see. But it turns out that neither view representations nor level of detail representations influence the visibility of sketches. (Position representations don't, either.) Sketches are either visible or not visible, regardless of which representation you're in.
Is there some way I can control the visibility of sketches, in groups?
we very often create parts/assemblies using skeletal sketches, problem we encounter is that when we use the copy command in the components area on the ribbon.
The problem we have is that when we open the new assembly and components they are still looking at the original skeletal sketch. is there anyway to copy the orginal skeletal sketch to a new one and the new parts look at this upon using the copy.
At present what we do is make a copy and rename the original file. Then open the assembly and it looks for the original skeletal sketch, so we point it at the new skeletal sketch.
This is not an issue when we have a couple of parts in an assembly but if you have a lot of parts in the assembly it si very time consuming.
In the course of working up a tooling proposal, I attempted to replicate a 3D part from a customer print. While doing so, I noticed that 3D Sketch will not, under any circumstances that I can find, allow an angular dimension between a line and a plane. The customer print has two pipes projecting at odd angles from a base flange, one of which has an elbow. The print lists datum dimensions for the open pipe ends and the elbow, and gives vertical and horizontal angular dimensions to define the directions in which the pipes emerge from the flange. I have defined these three datum points in 3D space without any trouble, but Inventor 2013 will not allow me to define an angle between these sketchlines and the XZ and YZ origin planes, or between these sketchlines and the faces of the flange base I've constructed.
I am currently waiting on a proper 3D CAD model from the customer, and I'm considering longhand trigonometric calculations to place these lines properly, but I find it very hard to believe that Inventor is incapable of constraining a line to lie along what is effectively the surface of a cone.

I'm having issues when I create sketches using the line tool. I should be seeing constraints as I create them and a green dot when the object is closed. This is not the case however, and when i attempt to extrude or offset the sketch I can only select individual lines.
View 3 Replies View Relatedi am working on an ipart. I have a spreadsheet with all the data and used the first line to creat the first part.
no problem.
i can add the remaining information to the table from the spreadsheet.
When returning to the drawing environment i can select a few parts that work and there are many more with "issues". So i move the first offending part select it and try to edit it. ( i know what i have to do to the sketch if i could just get into it) Also i have suppressed a sketch and inserted a new slightly different version (the issue) but, after getting out, i am un-able to edit this new sketch either.
the message comes back and says i cannot edit this part, and then....
unable to prepare the part for edit, updating your part is required to all the edit, update now?

I am trying to render some images and video of a design I've been working on.
This isn't an absolute necessity, but I would like to have my companys product and logo displayed on the monitor in the design. If you look at the screenshot what I'm trying to describe should come clear.
These images were just dropped into a sketch on the face of these two monitors.
When I go to render, the sketch image does not appear. It just renders the default face color of the part.
Is there something I'm missing?
As I learn more about Inventor I have been doing more and more skeletal modeling. It work well for what we build here. But the biggest problem is the visibility of all the workplans and sketches. I know of the buttons to turn them on and off, but everytime I make a sketch and edit a sketch, inventor default turns all of them on. Making it impossible to see what you are working in the assembly enviroment. Not only that, it bogs down my machine untill I turn them off. Same goes for workplanes, if I create one the rest appear.

It was OK up until recently, but now it would not show any sketches no matter what I try to do.
I would hate to recreate the view again.
I'm working with a series of 3D sketches. Some sketches must remain visible as reference. While creating the sketches, the dimension call-outs grow too distracting from the linear sketches. Is it possible to hide, or toggle off/on the dimensions while leaving the sketch geometry visible?
View 3 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.
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?
