AutoCAD Inventor :: Parametric Constraint Errors

Jul 24, 2012

I'm having a really difficult time maintaining my parameters when making changes to the part I've made in the attachment.  The control parameters for this part are:

-100 mm distance between 15mm circles
-1 of the 15 mm holes
-30 mm hole

I am new to inventor but I would also like to be able to set up my constraints correctly.  I'm also not sure if my sketches are ideal for this part either.  I usually get an error concerning my fillets from the base to the center support beam when I try to change the 100 to 75.

AutoCAD Inventor :: Constraint Errors From Suppressed Parts When Using LOD

Jun 28, 2013

I am trying to model a large Control panel assembly using Inventor Pro 2011. It comprises of a main assembly with several adaptive sub assemblies containing the various items. (Relays assy, label assy, fixing assy etc). All works ok until I start using Levels of Detail to enable me break the assembly into smaller workable parts. I.e. Left door, right door, main panel full, main panel no doors etc. These will be used to create view reps from for my drawing views at a later date.

The problem I am having is I keep getting constraints failing on parts which are suppressed in various levels of detail. An example of this Is when I go to right door LOD and do a rebuild all, I get constraint errors from item relating to the main panel which is suppressed. I can suppress the constraint causing the error but when I return to the full panel LOD the constraint is still suppressed and the parts appear In the wrong place.

AutoCAD Inventor :: Assembly Constraint Errors When Resizing Component

Mar 30, 2012

I have an assembly that is nearly completed.  I am trying to change the lengths of two side rails (arrow pointing to one of them).  On each end of these rails are several components that have been constrained to the rails. 

When I change the length of the rails, many of the constraints show errors.  I expected that all components would move with the ends of the rails as they are shortened since that is where they were constrained, but this has not happened.

The constraint recovery tool has not been useful to me.

AutoCAD Inventor :: Constraint Errors After Performing Replace Component?

Aug 27, 2012

We have just upgraded to inventor 2012 from 2009. I had a simple .ipt created from a 3/8" grade 50 sheetmetal template in an assembly, and decided that it could be 1/4" grade 50. I originally went into the original part and changed the sheet metal default to 1/4". After returning to my assemble and performing a refresh it blew away all my constraints I had on the .ipt after the thickness change. I also tried doing a save as on the ipt then changing the thickness as a new part number and performing a replace component with the same results to my constraints. I've also noticed issues losing constraints by performing simple replace component commands on similar sizes of TS but just changing length. Has something happened to our templates during the migration to the new version of inventor? I don't remember ever having this many issues in 2009 when replacing components of similar geometry with just a different length or thickness.

AutoCAD Inventor :: Angle Constraint / Drive Constraint

Jul 30, 2012

I am designing a vertical axis wind turbine just for some practice (just started using Inventor) and everything was going smoothly until I tried to "animate" it spinning.  First, I set up a work plane that goes through the center of the structure, and then I clicked angle constraint "explicit reference vector." After watching several youtube videos, I figured that I should click on the work plane, click on another reference point, and then click another point that would be orthogonal to those two (right?). Well after I choose the first point, Inventor will only allow me to choose the center axis  as the second option (which I think should be the third option).

AutoCAD Inventor :: Way To Make Parametric Assembly

Jan 5, 2012

find out a way to make some sort of parametric assembly.

Where I work, we make conveyors and those conveyors need legs. Those legs are all built the same except for the height and width. They are made of 2 tubes with a cross shaft between them + bolts, washer, plastic end cap.Is it possible to create some sort of iassembly or ipart for this? When creating a conveyor I would like to choose the height and width of those legs when I import them into the assembly.

AutoCAD Inventor :: Drawings - Break View And Parametric Parts

Oct 25, 2012

I have a parametric assembly and some of the parts in this assembly require a "Break".  When the part dramatically reduces in size the part view disappears as the part is now located in the "Break".  Delete the "Break", re apply the "Break".

I would like to be able to constrain a Break to the part, either a sketch on the view or maybe from Workplanes in the part.

AutoCAD Inventor :: Developing Parametric Spreadsheets To Drive Modelling

Aug 7, 2013

We are a transport engineering firm in Queensland and I would like to develop a spreadsheet that can formulate cross member distances and recalculate to add or remove cross members.

The basis of this is the overall size of the body we are building.

For example: The maximum width of a body in Australia is 2.5metres overall. Our cross members would be 6 mm shorter than the overall width of the body to allow for 3mm end caps to cover the open ends of the cross members. So the length of the cross member is width minus 6, or , parametrically the length is (overall width - (endcap thickness x2))

The body length is the tricky one. We have a maximum spacing on the cross members. This will vary from size of body to size of body. EG the spacing on the small 2 tonne body will be different to the spacing on the 12 tonne body etc. So lets say we want to have maximum spacing of 450mm and a minimu spacing of 300mm between centrelines of the cross members. The overall length of the body will also determine the number of cross members required.

On top of this there is the front and rear coaming to take into consideration.

So the formula would be ((overall length - front coaming - rear coaming) divided by cross member spacing)) then a check to see if the last space is what and then can we change the cross member size to take up that space without going over the maximum space. We would also need to take into account the width of the cross member section as well in this calculation.

EG if we have 150mm left at the end we could increase the cross member centres slightly to take up this additional space without going over the maximum space allowable.

AutoCAD Inventor :: Parametric Assembly - Control Size Of Components And Patterns

Jan 28, 2013

I am currently working on a parametric assembly using i Logic to control the size of the components as well as patterns. However, I have hit a road block in trying to figure out how to write a rule for resizing the last roof sheet in this assembly pictured below to be even with the frame. The rule below is what controls the roof sheet pattern based on the frame length. The problem I am continually running into is how do you modify a part which is in an element within the pattern without having it affect the rest of the parts in the pattern since they all refer to part. I can get since it is hard to find information on i Logic. 

Roof_Pattern_Spacing = Roof_Sheet_Width
Roof_Pattern_Count=Ceil(Parameter("Length")/Parameter("Sheet Metal Roof Section:1", "Roof_Sheet_Width"))

(Note: The red line symbolizes where I would like to have the roof sheet end.)

AutoCAD Inventor :: Creating Different Parametric Version Of Assembly From Master Part File?

Apr 24, 2013

I have created a parametric, multibody master part file to derive parts from it, and then put them in an assembly. See attached file. Now, I need 3 different versions of this setup (with different values of the parameter 'bending_angle').

What is the best way to do it? If I derive parts from it, they always follow the *actual* status of their master file. Is there some method to do this: "derive from this file, with parameter bending_angle=55deg", but keep the dependency relation, i.e. if I modify something on the master file, the derived part fill follow the modifications (with the value of bending_angle=55deg)

AutoCAD Inventor :: Fix The Angle Constraint?

Mar 10, 2010

Maybe I've just been doing it wrong for the last 5 years, but the Angle constraint is obnoxiously unpredictable. When I constrain a part in an assembly with an angle constraint from the assembly origin plane (or anything else), Inventor always has two solutions; a positive and negative.

Is there something I'm missing here, or is just a design flaw we have to live with?

AutoCAD Inventor :: Transitional Constraint Between Pin And Surface

Apr 16, 2013

I have a question regarding a transitional constraint between a pin and a surface within an adaptive assembly.

I would like the pin and the surface to be transitional only when the two parts "interfere" with each other.

At the moment with the example attached part A is remaining tangent to part B, restricting the necessary movement of part B to function properly in the mechanism.

In simplified terms I need part B to be able to break free of the "transitional constraint" of part A under certain movement conditions within the mechanism.

AutoCAD Inventor :: Deleting Coincident Constraint

Aug 15, 2008

I have noticed what I consider a bug in AI2009. When trying to delete a coincident constraint using the show constraint command, it is impossible to do so. All other constraints I can delete while I am in the "show constraints" dialog box, but not coincident constraints. As soon as I get out of the "Show constraints" command, the yellow dots are still showing and I can then hover over them and they highlight so I can delete them. Is this how it was intended or should I be able to delete them like the others while still in the "show constraints" command?

AutoCAD Inventor :: Revolution Constraint For A Bolt

AutoCAD Inventor :: Assembly UCS To Part UCS Constraint

My need is to assembly parts into an assembly by a known position in the assembly. The part has a UCS and I create  UCS on the assembly programatically. What I cannot do is to constrain the two UCS. I tried this (Inventor 2013 x64 on W7/W8 64, c++ 2010 by the way DEBUG mode is not working from the IDE):

       CAssemblyComponentDefinition compDef = doc.get_ComponentDefinition();
       // MOdules UCS
       CUserCoordinateSystems coords = compDef.get_UserCoordinateSystems();
       CTransientGeometry geom = m_InventorApp.get_TransientGeometry();
                    CMatrix matrix = geom.CreateMatrix();

AutoCAD Inventor :: Drive Constraint In 2013

See attached screen shot.

To activate the new position of the assembly of approx 5k instances takes about 5 minutes in IV 2013 when using Drive constraint. The larger the assembly the longer it takes

In IV2011 takes about 10 seconds. I've never seen the "Not responding" sign in Drive constraint window in previous versions. I'm just wondering how can avoid this "New feature" of 2013.
