I have a part that I want to have made by rapid prototyping that will in turn be used as a pattern for casting alloy metal parts. I need to apply a factor to the part to compensate for the shrinkage that occurs when a metal part is poured in a molten stage and will cool to slightly smalller dimensions than the mold. Is there an easy way to do this without having to recreate the part to slightly larger dimensions?
View 2 RepliesWhen using mtext and a background mask and try to modify the border offset factor from the default of 1.5 , the factor reverts back to 1.0. If I type in 1.25 or 1.75, it will not save it and revert to 1.0. If I put in a larger number like 2.0 or 3.0, that factor will be retained.

I've found shrink wrapping it as a surface causes problems with the video card when rotating the model and placing views on a drawing.
I have a part that was sent to me from a vendor. It was a large 80MB part so I put it in an assembly file and shrinkwrapped it to reduce the size of it. Now it is transparent and I can not figure out how to turn it off.
View 8 Replies View RelatedI have a part which is lets say 10ft long. Now I need to modify that to be 9.5ft. Is there a simple way to remove that .5ft from the center of the part?
I just need a way to cut out a .5ft section in the middle and then put the two remaining pieces back together. Doing this would be much easier than editing the sketches for the part, especially since I may have to change the amount that is cut out and that would change the number of holes and features.
Attached is a picture of the parts i have to edit and some lines to show the section that needs to get removed.
What is the purpose of creating/using shrink wrap substitutes? I thought that it reduces the file size, but noticed that some files turn to be larger after shrink wrapping it. ?

When I take an assembly and try to shrinkwrap it (with the Solid Bodies option) the file still has all the internal ribs and fillets and stand-outs. I have created extrudes to fill gaps and holes and even tried to create single pieces to assemble later to no avail.

About Substitute Shrink wrap parts, it doesn't automatic update when I use UPDATE or even REBUILD ALL inside the LOD with it, even if I don't break the link with the assembly it doesn't update, so I have to go in each assembly with Substitute parts ( with are many in huge projects) and then verify with "Check for updates" in the correct LOD (which in some cases are more than one per assembly). Is there a way to update them direct from the main assembly with rebuild all or something like that ?
View 1 Replies View RelatedIn the attached report, safety factor is se to calculate from ultimate tensile stress (485 MPa), and it indicates 1.33 with stresses:
Von-Mises: 323 MPa..............SF = 1.5
1st principal: 303 MPa.............SF = 1.6
2nd principal: -181.2 MPa....... SF =2.67
So, how is inventor getting 1.33 ?
EDIT: if I set it to calculate from yield ( 260 MPa) it accurately reports SF = 260/323=0.8
EDIT: added part file
I'm trying to create a report on a stress analysis I've made. Reading the report I don't find any result on safetyfactor. When I was browsing the forum I found a thread concerning safety factor and a report file attached. My report is missing some of the information that I found in this attached report (such as "result summary".
View 2 Replies View RelatedAny way, using iLogic, to get the K-Factor from a flat pattern sheet metal view on an idw drawing and add it as a note.
I'd like a rule that would access the flat pattern on the drawing, get the K-Factor value and then create a note that says, for example, "K-Factor Value = 44".
I see in the iLogic Snippets there's a Get Active KFactor under the Sheet Metal section, but I don't know where to start.
i want to ask is there any scale factor function in Autodesk Inventor 2012?
this is because all my drawed part are already full constrained and I want to enlarge it to some factor?
I have a set of sheet metal parts modeled in inventor that are produced in a wide range of sizes and several different sheet metal types.
The dimensions (length, width, flange size, etc) are driven from a spreadsheet. I would like to be able to have the user update the K Factor from the same spreadsheet by selecting a sheet metal type.
The sheet metal type and K factor are not listed in the parameters list with the other model dimensional data, so I'm not sure how to proceed.
I am trying to apply a torque to an adapter to replicate it being driven. I have constrained it and when I add the welds and simulate, it freezes at the 'computing mesh' stage.
View 6 Replies View RelatedI am wondering how best to apply drawing dimensions to a view. I am using VBA (Inventor 2010 x64) to modify a template skeletal assembly and save it. I have succeeded at generating the models, drawings, and drawing views, but have hit a wall when I attempt to automate the process of applying drawing dimensions.
I attempted to use GeneralDimensions.Retrieve with the DimensionsToRetrieve parameter, as I wish to retrieve only a few dimensions. My testing, however, indicated (and the helpfile confirmed) that the DimensionsToRetrieve parameter only work if the DimensionConstraint objects belong to a drawing sketch, and I'm retrieving dimensionconstraints from a model sketch. It appears to me that I will have to retrieve all dimensions and then somehow delete the unnecessary ones. This seems unusual to me--is there a better way? Can I, for example, retrieve a single dimensionconstraint at a time from the model rather than all of them at once? Perhaps its suitable applying drawing dimensions without retrieving them from the model?
Is it possible to set a time delay on an applied force in simulation 2012? I would like to apply a force for a set amount of time?
View 5 Replies View RelatedI'm working on a project that has a LOT of structural steel so I've been using Frame Generator a LOT. At first, the delay I got when applying an end treatment to the structural members was no big deal. Hundreds and hundreds of trim / notch treatments later, the 6 to 9 second delay each time I perform it is about to drive me crazy. The trim/extend function lets me select a large number of members to trim to a single face, which is great. The notch function, however, has to be done one at a time. I have buttons programmed on my SpacePilot and mouse to reduce the number of mouse clicks, but once I click OK, there is always a long pause before the treatment is applied.

Basic understandable breakdown of the meanings of the 3 constraint options when running a stress analysis - pin, frictionless and fixed ?
It is difficult to tell if I am using the correct ones(s) and Inventor does not give a detailed enough description of how to apply them and which ones to use. I have attached an image showing what I have done so far, the constraints in the drawings are 1 pin constraint to the bolt (only fix axial direction checked) and 1 fixed constraint on the I-beam surface.
I have a set of dimensions on my drawings however where the dimension is displaying as 6mm in a vertical plane this is quite difficult to distinguish as it could be misread as 9mm. Is there a way to add an underscore mark on the 6 so no mistake can be made as to it being a 6 and not a 9 ?
View 9 Replies View RelatedI am trying to apply a load lengthwise on a 2 x 2 x 3/16 angle at the center of gravity using "stress analysis" in inventor pro 2014, but it won't let me apply the load at this point. I know that the load would be floating in the air at the center of gravity, could this be the issue?
View 5 Replies View RelatedI'm trying to apply the right constraint in stress analysis environment.
How would I apply the right constraint? And to which face of the wheel or axle should I apply the constraint to get right results.
If I'm applying the sliding connection to the face of the wheel in z direction, the model will stop stress analysis with an error of "not enough constraints"
if I apply the sliding constraint to the inside of the wheel on the surface of the circle, I get the result as attached. I get 0 reaction in the Z direction which is wrong and should be zero reaction in x direction. How do I get it right?
The correct way to me would be a constraint that would only take forces in the -Y direction, same direction as gravity.
The wheel should not have any other reaction than in the Y direction. Hoe do I define that constraint? In my model the wheel are free to rotate on the axle.
I'm attaching both the general arrangement and the reaction report.
I'd like to know how inventor defines the center of rotation when you apply moment load on multiple faces at once. I'm not basically able to define where exactly I need that axis to be. and I dont understand where inventor assumes that axis is. if you take a look at attached model, obviously the resultant forces caused by the applied moment are bigger on the single pillar located on the extention, thats why its been displaced more than the others, but where exactly is center of rotation. I'm trying to avoid modeling of the section above this which technically transfers the moment thorough shear pins on the structure I have modeled.
View 5 Replies View RelatedJust started having a play with ray tracing in Inventor 2013 Pro & I'm quite impressed how quickly you can get a rendered view of a model. However, it seems no matter how I set up the lighting or the shadows in the 'Settings' menu when I click on 'Tay Tracing' it seems to default back to some original settings. The shadows & lighting in any of the drop down menus don't seem to be applied. eg. I select 'Two Lights' from the menu, then select 'Settings' I then adjust the shadows & the lights from within the menu. It all looks good on the screen & click Ray Tracing & everything that I've done doesn't get applied? However, when I cancel & stop the Ray Tracing the shadows & Lights are still there.
View 1 Replies View RelatedI noticed when creating assemblies, applying a positional constraint, the parts don't move. In order to get the parts to "move" to their constrained position I have to try and drag them with the mouse then they snap into place. Also updating the assembly works as well.
What setting could I have changed so that once I press apply on a constraint it moves the part immediately?

I have been sent a dwg and I am trying to shrink a group of items collectively.
I cannot find a way to reduce the size of it I have tried scale but I don't want to work out the scale for each group, I tried stretch but its not a single item...
I am trying to reduce the width of the objects from 140mm to 110mm whilst retaining the ratio between all objects.
I have always struggled with AutoCAD's text masking. I love the masking ability which makes drawings that are clean looking and easier to read. My issue is with the way the mask border is created. The mask creates a rectangular border that does not "shrink wrap" around the text. This can lead to masking more text than originally intended.
I am looking for a quick and easy way to wrap the mask around text. Right now the only way to accomplish the desired result is to explode the text into single lines and then mask each individual line. This creates issues with leaders and is a more time consuming process.
I recieved a dwg file from an architect (away on vacation and can't reach to ask). I'm working on a kitchen layout and the scale is off by a factor of 12. My symbols are much too large and if I draw a 36" line it comes out to be 36'.
I've gone into Format-Dimension Style and don't see what to correct in this area. Obvioulsy I can expand the drawn item by a scale of 12 to make my blocks fit but obviously screws up the dimensions...
And yes, we're still running AutoCAD 2000
Having some trouble with some annotative hatches. Notably ones with patterns in them? I am testing them out in multiple viewports of various scales and for the most part they work great. But every so often in a particular viewport they either disappear altogether or shrink to a smaller size and bring my AutoCAD to a dead crawl?
