AutoCAD Inventor :: How To Document Frame Sketches

Sep 15, 2013

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?

AutoCAD Inventor :: Linking Frame Generator Parts To Sketches

Mar 2, 2012

I dont know if this is possible or not. What it is, is that we use skeletal modelling, so we use intelligent "master sketches". Now we are just starting to use frame generator also and we want to combine the 2 methods.

An example of how we work is this.......

Lets say, we are designing the base of a basic frame. Now, we sketch in the profile of the RHS that will run along the front of the base and we also sketch in the elevation view of this RHS (see snip 1). This gives us 2 sketches to derive in to create a new part of RHS.

If I change the size of the profile of the RHS within the "master sketch" the newly created RHS part will update to suit. This also applies if I change the length of the RHS within the elevation view within the "master sketch".

So, now we want to add in a 5mm thick plate that sits flush with the top of the RHS, we sketch in a 3mm thick rectangle and make the top line colinear with the top line of the RHS profile sketch (see snip 2). We would then derive through these sketches and use them to create this plate as an ipt.

So now we have 2 parts, 1 length of RHS and 1 piece of plate. If we place these to parts into an assembly and ground them to their "root" then the plate will be sitting flush with the top of the RHS.

If I change the profile of the RHS to 50mm taller in the sketch, then the plate will move up to suit and stay flush with the RHS in the assembly.

NOW, what we want is to use frame generaotor along side this method. Instead of deriving through the first 2 sketches to create the the RHS, we want to create the RHS using frame generator and the elevation sketch BUT what we also want is when we change the profile sketch of the RHS, the Frame generator generated part updates to suit the altered sketch. The reason we want this is because we control all our full assemblies using sketches.

Lets take the same bunch of aforementioned sketches and create the parts using FG.

So I have the RHS profile sketched out at 100x50 and the plate sketch sits colinear with the top of this.

I then go through the motions to create the RHS within FG.

I choose RHS from the drop down menu, then choose 100x50 from the "size" drop down menu. I then use the elevation sketch to specify the length.

Now if I increase the size of the RHS (to 150x50) within the sketch, the plate will move up to suit BUT the actual part of the RHS which was created using FG will still stay the same size (100x50), and the plate will be shown as floating within the assembly!!!

If I do it the other way, i.e. change the size fo the RHS within FG, then the sketch will still show the original size and the plate will still sit flush with this original size. This will show the plate as sitting too low in the assembly!!!

Is there anyway at all, that we can link the profile sketch dimensions to the FG generated parts, so that if we edit the profile size of the RHS to a larger or smaller size then FG will automatically alter the generated part to suit the profile sketch???

Is this at all possible???? Or will we just have to alter both the sketch AND the FG part? We really don't want to use adaptive parts within our assembly, we always just control our assemblies with our "master sketches".

AutoCAD Inventor :: Combining 2D And 3D Sketches

Dec 13, 2012

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.

AutoCAD Inventor :: When Detailing Generated Frame View Shows Elongated Frame Members

Jul 26, 2012

I come across this problem from time to time and generally either just ignore it, if the detail is destined for in house manufacture, or alter it in autocad if it's destined for exterior suppliers.

Our guard frames are manufactured from extruded aluminum section (made by a company called palletti) I have when needed created a new frame generator frame member for each new x-section that we wish to use. I then draw a 2d sketch for the base frame skeleton and then a 3d sketch for all the frame work above. This I then use in an assembly to create the framework.  This framework assembly then goes into a second assembly where the framework is then adorned with all the accoutrements that make up a guard frame that we can then order as an assembled frame, panels feet, hinges et al.

When placing the views for the detailing of the second assembly sometimes the view will show the wrong length for one or some of the frame members.

;note how the left and right views are different and how some of the frame members are elongated on the lh view.

 I'm guessing its because of the home grown frame members but all seems to work well other wise and this only happens infrequently.

AutoCAD Inventor :: Functionality Of Assembly Sketches?

Oct 7, 2011

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.

AutoCAD Inventor :: Moving Sketches Between Parts?

Feb 8, 2012

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.

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?

AutoCAD Inventor :: Skeletal Sketches And Copy

Oct 29, 2012

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.

AutoCAD Inventor :: Dimensioning Angles In 3D Sketches

Oct 4, 2013

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.

AutoCAD Inventor :: Cannot Edit IPart Sketches

Dec 19, 2011

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?

AutoCAD Inventor :: Rendering Sketches With Images

Jul 23, 2012

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?

AutoCAD Inventor :: Visibility Of All Workplans And Sketches

Jul 24, 2012

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.

AutoCAD Inventor :: Access Sketches And Features Information

Jun 23, 2012

- when modelling a part file in Inventor, only the dimensions we set (dimensions we give a name and a value), are listed in the parameters table. This way, its possible to export the information listed in that table. 

- the information listed in the parameters table is based on sketches and features dimensions, as obvious.

So , my question is: is it possible to access the information (dimension values) contained in a feature (or a sketch) without setting a specific name or value to it?

For example, in the attached pictures, if a rectangular form is drawn and the dimensions are sett, these will be listed in the parameters table (see attached  "pic1" and "pic1 - params").

But, in the other hand, if the same rectangular form is drawn, but this time without setting any dimension, the parameters table will be empty, obviously (see attached  "pic2").

After this, i can surely presume that Inventor saves or keeps this information somehow, somewhere, without having to set dimensions or values.

So, my question is: is it possible to access sketches and/or features information without setting this values?
