AutoCAD Inventor :: Imported STP File For FEA
Nov 26, 2012
I have been given several drawings to perform FEA analysis. These files are solidworks files, but my school does not have the FEA package so I had to export the files to a .stp file to import it into Inventor.
On top of that, the SolidWorks file I need to analyze is an assembly, so I 'saved as' the assembly in Solidworks as a part to have one solid part.
The file seems to import fine at first, I can create sketches onto faces. But when I go to create an analysis, and try to set a fixed point or force load, I cannot select a face. I tried to "cheat" and add some material to the faces I wanted to use. When I run the analysis, it just doesn't recognize the initial material in the 'mesh'.
I CANNOT include full screenshots of the system, due to the nature of the project. I can show small clipped shots of the software status, but not the drawing itself. If seeing the "model" box on the left would work, I can supply that with the drawing names blacked out.

When I import a step file, the color/texture of the step file has gone way off from expected.
Before, the same model used to be gray, now most models have got a green pcb texture, and there seems to be no way to correct it in the model/solid properties.

A colleague and I are working on a large assembly together, and we have received several .stp files from a customer (originally created in ProE), many of which are sheet metal that need to be unfolded and flat patterns made in drawings. The sheet metal default thickness has been changed to what the material thickness is. We have measured the edges on each side of and the radii of the bends, and they all appear to be consistently uniform. Yet, we get an error when trying to unfold or flatten the outer two bends. The customer sent us a flat pattern .stp file as well after letting them know we could not unfold the part, and there are many dimensions that we have to manually inserted to the drawing with the flat file because it does not have the bend information in it.
Is there something that we are missing to make this part unfold all the way?

Got a part from our vendor. When I place this in an idw, some of the lines are missing.
In the model, there are no surfaces. None of the solids failed on the import. No problems appear in the model browser.
First tried turning on Tangent edges in the idw. No joy there.
When I right click on the view in the idw and select "Include All Surfaces", the edges are shown while the view is computing, but after it computes, the edges are gone again. The .step file that was sent to me is 10MB and the ipt is 32MB.

I have recently downloaded a .stp file of an AOD pump from a manufacturers website. Once I imported it into Inventor the appearance is a rust color and all features have a yellow outline. I am able to insert into a main assembly but I have not found a way to change the color or get rid of the yellow outline. See attached screen print.

I have imported an IGES file in Inventor and I need to dimension and detaill the piece in a 2D drawing. The thread and hole wizard does not recognize the holes in the workpiece as holes. Also I sectional view does not display hatched areas of the workpiece even though I have the display option checked on. Is there any sort of feature recognition within Inventor that I can use to import all geometry so that inventor understands?
I am working with 2011 Pro and have about 1500 hours on the program so far.
I was considering redrawing the workpiece by creating a part within an assembly and overlaying the two pieces on top another and using refernece geometry but this might not be the most ideal method.

URL...how to move the origin of a part when you want a common origin for everything. in iv2012 you also get angles about axis, in greyed out boxes.
In a test assembly I can get the offsetting to work, but not the rotations. The part I want to edit origin of is rotated in all three axis.

I have an interesting problem. I have imported a shp file from a state agency. This file contains contours for an area. When I tag the pline, it shows a "zero" elevation, but shows a numeric elevation within the DXF_ELEV feature.I am needing to convert these to pline with elevation to work on in autocad. how to get polyline w/ elevations to export from c3d?

I seem to have issues with this particular file from sketchup pro, Ive tried converting the .bak file without luck, on my mac the file briefly opens then closes.
I am using autocad 2013 student and also tried opening it on other computers with the same result.

I have been working on a site layout, and the engineers changed the final topo. I have imported a DEM file, and changes all of my pipe networks to reference this final grade. But all of the pipes I have placed do not reference this surface, but all of the networks do. Other than changing all of the pipes individually (which is what I have started to do through Pipe Properties) is there a quicker and easier way to have all of the pipes reference my new surface, and also is there a quicker way to apply my rules to this new surface other than the same way (through Pipe Properties changing my rules, and right click to apply rules).

Previously i`m using version 2009 and importing Google earth image and surface works fine. However, recently i tried with version 2010 and i`m having some problem here (imported surface / contour seems ok but the image is too large like 3x or 4x). How to solve that?

I am looking into using the Survey Database for the first time and noticed it linked back to the imported file from which the points came. However, my question is when the points are adjusted within the AutoCAD file is there a way for this adjustment to link back into the imported point file. I am trying not to have a situation where the data is different between the imported file and the autocad file.

It strikes me that there should be an easy way to do this, but it eludes me at the moment. I've used "Connect to Data" to attach a .shp file export from another software, specifically a Windmill computer model. The geometry and data comes through, but the table contains no coordinates, which is what my vendor wants. The drawing overlay's georeference info very closely (within our tolerances) and the Coordinate System is set.
How to suck that coordinate info off the drawing without spending a week clicking on each of 8600 points and typing LIST?

What is the correct format for the .csv file to be imported into QTO manager?
The attached file loads into the QTO manager, but I cannot get the "units" to behave.
Every item I assign to an line or pline gives me a count instead of a length.
Also, how do you change the precision (decimal places) of the report.Windows 7 Pro x64

i want to import dxf into my sketch, and than Extrude shape to make a box. I cannot do this because Inventor says that he can find closed regions. Dxf is made in adobe illustrator.

I am currently working on a model which was first created using inventor. Its is a drawing contaning tanks and pipeworks.I have looked into the drawing and have noticed that all the parts are 3d solids. The file size is over 100mb which makes the drawing impossible to work on.
Resolving the file size issue? Maybe converting all the solids to blocks?
I will be able to have access to the original inventor file and possibly try exporting smaller parts of the site and xref only the relevent parts of the site as required for each drawing if that makes sense.

When creating a core & cavity in within Mold design a :
Failed to join the runoff surfaces onto the base body. Entity-entity intersections are detected within the product.
Message appears.
Exporting to fusion, re patching fillets, healing to 0.000001mm, saving as SAT, IGES, splitting & deriving - fixes some thing but breaks others.

I have imported an .igs and would like to use it on my assembly.
Step that I created.
1. DL an igs files, then open it in Inventor 2012 Product Suite.
2. Save as .ipt,
3. Create a new .ipt and then DERIVED the save .ipt, change scale to 25.4
4. Save the part
5. Open .idw and place the part you just save.
Result: Notice that nothing is visible. WHY?

How I can override the CoG for an imported part. I have an imported motor as one part, Inventor sees the CoG as though it's one solid piece but in reality this is not true. I can override the mass so why cant I override the CoG???

A customer sent me a .step file. In order to produce the part that I need, I wanted to add some machining to his original part. Os I derived in his part and then added the features that I needed. Just a few tapped holes in one side.
Now, my customer made a few changes to his original part (added some detail) and he has sent me his new .stp file. I did not think it would be any problems if I just overwrote the original stp file with the new one. But, if I do that, when I open my part, Inventor complains that the updated part is part is not usable.
I tried saving the imported file as a .ipt and then bringing that into an assembly and doing the machining there. But, now when I replace the imported file with the updated version, my features fail.
Is there a workflow that will allow me to update the part that is derived into another part?

I have recently ran in to an issue where the imported AutoCAD blocks disappear when I export to .dwf, this only appears to happen after I add the revision table. If I were to add the revision prior to importing the blocks all seems ok. I have tried removing the block and deleting the definitions from the Inventor.dwg then re-inserting once more and I still have the same issue. The only real working solution I've found so far is to start from new and reproduce the drawings.

I have to rebuild 3d geometry from existing *.pdf drawings. What would be the best way to proceed?
I thought an option would be to import the *.pdf in a kind of layer, rescale it and sketch on top of it.
However the pdf importation fails. How to import a *.pdf in sketch mode?

I accidentally included a file rename when I just imported a batch of several hundred pictures. I violated a rule that I teach my own Lightroom students, and that is to look carefully at the import panel choices before proceeding.
How can I correct this so that the files are named as they originally were? I know how to easily fix the filenames in Windows (using a tool called BulkRename, for example), but then I'd have to "find" each image one-by-one and correctly point to the renamed version. I tried selecting all the images and then using F2 to rename, but none of the templates allow deleting a portion of the filename.
P.S. Here is an example of what I mean:
ON CARD:
IMG_0001.NEF
...
IMG_0300.NEF
WHAT I RENAMED TO ACCIDENTALLY:
IMG_0001 {shot by John Doe}.NEF
...
IMG_0300 {shot by John Doe}.NEF

I was given a STEP file that was created in Solidwoks which when opened in Inventor 12' is a surface.
The surface can be successfully thickened after it is stitched, prior to stitching it fails due to it's complex obround, tapered, bell shape. However, because thicken only thickens perpendicular to the surface I end up with a lot of unusable ends with crazy angles and in many cases additional phantom surfaces which I cannot cut off or sketch on because they don’t really exist. Thickening has not been a serviceable option to this point.
All other techniques I try when making this model from scratch fail or do not match the original surface. Measuring the surface is difficult because the only measurements we get are the lengths of the loops, no radial measurements. Additionally, when I enter the solid I created from scratch into an assembly (whether it’s geometrically correct or not), I cannot constrain it, I can’t click on anything but the working planes – no surface, face or edge can be picked on the solid itself.
Making surfaces into workable solids? Is there anything I should do different? Is the sequence I am using incorrect? Correct order of operations they use to successfully create a solid from a surface?

When I bring in a .sat file, I see these little "i" in the browser. The red Cross is dimmed. If I hover over the icon, it doesnt tell me anything. I can right click on Base2 and choose edit solid, and the "i" goes away, but something is still not right. I know something is wrong, because the mass is not correct for this part.
Notice the green check by "Base 3"? After I edit "Base 2", I do not have a check by it.
How do I get this to report the mass correcly.

Attached is design I am working on and I have imported standard parts from Carrlane. These parts are in surface type and I could not see them in Inventor DWG though they are visible in assembly. How can I convert these imported parts to solid or is there an easier way out of this ?

I'm currently creating a procedure to manage a standard part library.
For that, I'm trying to import downloaded STEP files from suppliers online libraries, and some of these STEP files contain assemblies.
I can open them as wanted in Inventor (1 .IAM and .IPT files), problem is I can't edit .IPT names. I can only rename them in Windows, but I would like to rename in Inventor before saving for the first time.
I would like to have something like that, with "Assembly" the assembly name:
Assembly.IAM
Assembly_1.IPT
Assembly_2.IPT
Assembly_3.IPT
...
How can I do that without renaming in Windows?
I attached the STEP file I'm using, downloaded form McMaster.

I recieved several .stp files from a vendor and most of them imported without incident. One part is giving me a major headache though. The envelope of the solid body is much larger than the actual part. This is causing the origin to be skewed by several orders of magnitude. Any way to trim down the envelope to the part size?
