AutoCAD Inventor :: How Do Representations Handle Sketches
Sep 18, 2013
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?
I have set up my assembly file so that it has the master and two other positions. When I switch from position one, to position two, it works fine. But when I go into inventor studio, and try to create an animation by using Pos Reps, it will not do anything.I do sometimes get an error saying that Excel is required. I do have the latest version of Excel installed on my machine.
Does Inventor 10 not allow position representations to be created in Weldments? I Right Mouse Button (RMB) click on "Position" under "Representations", but "New" is grayed out.
There is some association between prints and view representations i am missing.My typical process is:
-Build a model -Create a representation -Lock the representation -Create a print from that representation -Create a new representation and continue to work on the model
When i go back to the original print there is parts flying everywhere (see attached picture - hope you get a kick out of it)
I'm using 2011 pro. When I try to animate a positional rep in inventor studio, it complains that I don't have excel installed. (see attached image) although I do have it installed. I've put the hotfix on for excel, with no effect. I've repaired inventor and repaired excel no fix though.
Whenever I do a model update through an ilogic form my View representation changes from default to master and then i have to go and manually change them back to default also in my idw files in order to update the drawing files I have to go in and change the view representation from default to master click ok and close it then open view edit set it to default and close. Is this normal? Is there a setting so that my model views will stay on default?
is there a way I can "Unlock" my MASTER view in representations. I keep having to create new views as the MASTER is locked and for some reason I can't unlock it.
I'm configuring a band with different supports. Each support is configured with a range; 600-900, 900-1200, 1200-1500 etc. those ranges can be adjust by 50mm and those steps are specified by the pos reps (see attached image).
All the different supports are put in the top assembly and in this assembly I want to switch between the positional representations. I tried to use:
Is there a way to reorder positional representations in the browser. I'd like to keep them in order of how the assembly will function. That way, it's easier to create the animation in Studio. See attached image.
I created view representations in my assembly, for example a column with k-polates and base plates, the column is a FG part, so now i create drawings and place views on that drawing, what i am askign for is I want to place the name of the view representation in my view label as a paramater so in the event i change my view names in my model they update in my drawing, this is important because i can create a cross referance to my 3D DWXF file views.
Design view representations in an iPart file are not included in the generated members after installing Inventor 2014 SP2 (and also in Update 1).
In the attached part factory, the two work planes are included in the members. They would need to be individually set invisible in each assembly view representation because the members only have the Master view representation.
Is there a way to have the parts list filter to show only the visible parts from the view representation, especially the quantities? I thought that was what the filter is for. And if not then what is the filter used for?
Inventor 2013..I am trying to show a part in a drawing of three different configurations of a casting:
1) Rough as received from the foundry
2) Partially machined or rough machined
3) Final machined
What is the most basic bullet-proof way to show this? Three different models?What is the procedure to change the representation to show changes in the model?Why does suppressing a machining feature in one representation change all representations?The rough part is brought into an assembly and the machining or removal of material happens in the assembly.
I have an assembly with a client feature that contains client graphics. I have exposed the visibility (ClientFeature.Definition.ClientGraphicsCollection[1].Visible) to the user via a context menu option. Changing the visibility currently affects all view representations. Is there a way to associate the visibility with each design view representation?
What 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 want to fit a sketch that is to be laser cutted. i wanna fit 30 pcs on a rectangle, is there a tool who figures out the most optimal way to fit them in a rectangle?
I 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 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?
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.
i 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.
