On AssemblyConstraints what is the difference between EntityOne(Two) and GeometryOne(Two). When should one be used over the other?
Likewise with AffectedOccurrenceOne(Two) and OccurrenceOne(Two).
I would like to determine the Proxy ObjectType returned from Constraint.EntityOne (i.e. If oConst.EntityOne = kWorkPointProxyObject Then ....)
Property EntityOne() As IDispatch**
how IDispatch works.
Dim oAsmDef As AssemblyComponentDefinitionSet oAsmDef = oAsmDoc.ComponentDefinition
Dim oConst As AssemblyConstraint
For Each oConst In oAsmDef.Constraints'Below will print the Enum 67120288 (kEdgeProxyObject) or 67119520 (kFaceProxyObject) if
'it is constrained. It will Err if a Work or Sketch Proxy Object is Constrained Debug.Print oConst.EntityOne Debug.Print oConst.EntityTwo Next
As you can see from the image below, the preview shows the weld I want and need, but as per the error message it is saying the geometry is no longer available. What does that mean? Anything to do with the fact that the pieces being welded together are custom CC parts? If that is the issue is there a remedy for it?

I gues this is another bug by Autodesk that is comming up in my stress analysis. Basically all work I have done is gone. The frame won't appear and get big "NOT AVAILIBLE" on my screen. There is no way to fix it because there is no red cross highlighted

View 4 Replies View RelatedMy 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();

I have an assembly wherein one part is mated to another grounded part, with a face-to-face coincident mate. The click + drag type of movement appears to move the part, while continually solving this constraint.
However, it seems like there is no way to do a rotation in the same manner, where the constraint is continually updated. There appears to only be the "Free Rotate" command, which ignores the constraints.
Is there really no way to do this in Inventor? The application is that I am laying out a mold for many, many small parts, and I am trying to move and rotate them into position to get good packing efficiency and density. Each part will be attached to a mold base with one of the aforementioned face-to-face constraints, then slid & rotated around manually.
This seems like a really important piece of functionality. Solidworks can certainly do this, do a part rotation in an assembly, while solving for existing constraints.

Motor Model 1:1 is used to turn the wheel holders at various angles. The part named "front gear spring holder" is supposed to revolve and turn the inner part of the "front wheel holder" My problem is that I want to simulate the turning of the front wheel's using contact sets or 3d/2d contact sets in the dynamic simulation environment. I do not know how to do this, but I'm almost certain the program is capable of doing so. Also the spinning of the front wheels must be able to be done along with various angles of the front wheels(while turning, the front wheels must be able to still spin with the front gear spring holder".
I have seen threads and articles that say that making gears with contact sets is not recommended or possible but i have two instances here where they work perfectly fine using the dynamic simulation with 3d /contact sets. Take a look at the simulation I have saved as well.
I will need more on this assembly in the future, including how to create bevel gears that work at 90 degree angles or spur gears with contact sets instead of just simulating their movements .
I am trying to add an angle constraint to an assembly of a ladder design. I need for the ladder to be able to be set at an angle against a wall and not vertical. The ladder design is such that the base brackets are fixed to the ground and the rest of the ladder may move about the axis of the bolted connection at the base of the ladder. I cannot get the angle constraint on the ladder to allow this.

I got a problem with editing angle constraint in assemblies. I tried edit property of constraint but it didn't move model. Simply changing Angle attribute of constraint item don't work.
Only way I achieved movemenet is
if(oOccurrence.Constraints[i].Name.Equals(name))
{
AngleConstraint a = (AngleConstraint)oOccurrence.Constraints[i];
Object oEntity1 = a.EntityOne;
Object oEntity2 = a.EntityTwo;
String sVal = "" + angle + " deg";
[Code]...
but this is really slow, as much as changing throught parameter:
if (assemblyDoc.ComponentDefinition.Parameters[i].Name == "d655")
{
Inventor.Parameter invParam = assemblyDoc.ComponentDefinition.Parameters[i];
invParam.Value = Math.PI * angle/180;
inventorApplication.ActiveDocument.Update();
}
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.
I have an Assembly2 in Assembly1. I'd like to insert Assembly2 to Assembly 3 without losing any constraints or adaptive feature to Assembly1, while Assembly2 replaced with Assembly3.

I've got a relatively simple assembly (attached) containing 3 iparts. I change the center component the assembly and I lose all the constraints. Only the length changes, I'm sure I did this before but yet it turns out to be an epic disaster.

If I have two parts as occurrences in an assembly, how can I programatically constraint two workplanes (one from each part) to a flush constraint.
My problem is that I can get the Occurrences, say ...
CComPtr<ComponentOccurrence> pTube1Occ = ...
CComPtr<ComponentOccurrence> pTube2Occ = ...
...but I don't know how to delve into these two pointers to get hold of two named workplanes within them. I'd then pass the two workplanes (somehow?!) to the AddFlushConstraint function.
get_SurfaceBodies doesn't seem right and neither does get_SubOccurrences.
I have a linear slide assembly, for which I've set up limit constraints in the open and closed position.
It all works well, with one being able to drag the slide open and closed and the parts stopping in the correct positions.
I then inserted 4 of these assemblies as sub assemblies in a parent assembly.
I then constrain another part to the 4 slides.
I want to just drag on this part, to make the slides move to open positions.
This is to check kinematics etc.
One cant do this. You can only drag one slide open, by activating that slide in the model browser.
Any way to make limits work properly in upper assemblies?

Why can't Inventor constrain an ellipsoidal contour with a line? We have pressure cylinders which uses a 2:1 ellipse. These cylinder get welded to a base stand fixture. The surface of the ellipse nestles in between contact points of the base stand, in this case lines of geometry. Yet Inventor can't constrain them as such. Any good workflow (at the assembly level) so that we don't have to ground components and use the Analyze Interference tool to make sure we are right on the surfaces? I don't understand why it will work for a cylindrical surface but not an elliptical surface.

We have some serious problems by creating assembly drawings with reference geometries in inventor 2010. Our target is, to create a drawing that look the way, the attachment shows (Picture-1) The sheet metal plates Pos 10-100 are an assembly. And the assembly in the back is the reference geometry. It’s a frame consists of steel sections. What we want: 1. The frame must be phantom lined in the idw. 2.
The Sheet Metal parts must be thick lined. 3. The Partslist of the Assembly should only contain the sheet metal parts and not the frame We have some ideas to solve this case, but each of them is nor perfect (please see the attachment Box.pdf) And there’s another problem (described in part 3 of attachment), we cannot position viewports or drawing elements to each other exactly. You have no possibility to give them dependencies. Also if you want to position symbols to each other. All of them are only near to be exact, but that’s a big problem. If you change contents of a viewport, another should be aligned to it, but that doesn’t work.
I'm trying to setup an assembly based on a complex 3D sketch. In simplest terms, if I have a sketch for the perimeter of a house, I'd like to add instances of a 2x4.ipt at specified locations automatically. That's not necessarily every 16", but rather wherever I put a specific geometry. I'm imagining two work axis or sketch lines, one along the perimeter to determine the location of the 2x4 and one perpendicular to determine the direction the 2x4 points.
In actuality my sketch won't be a rectangle, but rather a complex 3D spline, that's why I'm hoping to get some sort of automated process. And the current design involves somewhere on the order of 1500-1800 2x4s. Making the sketches and geometry will be nightmarish enough, I'd prefer to be able to breeze through the assembly portion.
I have an assembly with a few parts inside and want to create a new part(hose) in the assembly and link some faces from other parts within the assembly to my new part to show the routing of the hose.

I have geometry not updating after replacing a component in an assembly.
I have drawn part A and in the assembly environment I have projected cut edges on a XY Plane in a 2D Sketch.
After replacing component A in the assembly with part B (not identical but very close) i was expecting the projected geometry to update. But it doesn't. The "local update" button is greyed out in assembly mode. also the Rebuild command does not seem to update the projected geometry.
I can see the new 3d shape and the old projected geometry. How to get the projected geometry to update?

On one part, I have a bore hole drilled on a curved surface so the hole is actually an ellipse.
Now the other part I am trying to constrain together is the pipe that will be welded into the bore hole; so that is a simple circular pipe.
The issue is that the pipe has to be inserted 0.25" above the interior of the bore hole to allow for room for the weld. In order to do this I have tried to create a plane attached to the 3D ellipse and then constrain the pipe to be 0.25" above that plane. The problem is I cannot seem to create a plane attached to the 3D geometry; I cant even find a way to attach points, or pick the center point of the bore hole.
How to create a plane on 3D geometry and link it to said geometry. I'm using 2012, if that is necessary information.
