I place and fully constrain two components in an assembly them mirror them. To my surprise, the mirror parts are not constrained. I grab them and move them anywhere I want. I closed without saving, reopened and grounded the mirrored components.

Am guessing inventor does not allow getting the constraints when you mirror a part..but is there a work around or easy way to copy the constraints.
View 9 Replies View Relatedit is possible to make a constraint that utilized a parameter of a part within the assembly.
For example, if I wanted to use the thickness of a plate, which I defined in the part, could I call that parameter in a constraint?
Are there any C++ samples of the use of C Assembly Constraints? The syntax is so much different with VB a few real examples would be really useful.
View 2 Replies View RelatedWhy is it when I select multiple contraints for a component that I can use the delete key on the keyboard to eliminate them but when I select only a single constraint, I have to right click and select delete on the context menu. The delete key will not work on a single constraint.

View 1 Replies View RelatedIn an assembly we can set driven constraints to drive parts etc.. or we can set the contact solver to show contacts.
Is it possible to set something like a driven constraint but so it is flexible between the set parameters?
when creating designs i like to move stuff around with the mouse to see how it works and the potential problems that might arise etc.. however i would like to still move stuff around with the mouse but restrict the movements with constraints.
so if you have a hingy flappy thing, the constraints would be set so it can rotate round the hinge as required but also an angular constraint could be set do it would work between set angles, say 0 to 50 degrees and if it gets to the limit it stops?
Is this possible, I think it would be very useful?
I have a bunch of assemblies that are acting this way and I am not sure why.
I have built the parts and built the sub-assemblies with-out errors, once everything looks good I place the subassemblies into my top level assembly.
Everything still looks good with no errors.
I do a rebuild of the top level assembly and find 20 or so errors.
Most of the errors are bogus and editing the constraint with-out changing anything removes the errors, typicaly.
On a bunch of the sub-assemblies the error showed up in the top level assembly, so I edit the part only to find the constraint is relevant but with errors so I suppress it to remove the error. Save and go back to the top level assembly only to find there is another constraint error in the same assembly that I suppressed the constraint to remove the error. This goes back and forth between top level and sub-assembly till all constraints are suppressed or deleted for the sub-assembly. Then the same thing happens to another sub-assembly.
The only solution that I have found is to delete all constraints and rebuild each sub-assembly with the same constraints that were initially used.
How do I stop this snowball effect?
I want to use I logic to adjust an assembly constraint based on T/F value passed from a master sketch.
I have passed the paramater T/F and/or a user paramater as described in this thread using link (neet trick).. but when the code fires it only works on the true application and not the false.. if i open the rule and then close it the update button becomes available and when updated the false condition updates sucessfully. I have tried just re-running the rule to no avail. It seams that the only way I can get it to triger a false condition is to open the rule... close it and update.

View 2 Replies View RelatedIm after programmatically mating 2 components together in an assembly. My stages are as follows:
1)Create New Assembly
2)Add .ipt's
3) One-by-one, mate all the parts together (each part has a plane named "WPStart" and "WPEnd". In each part im after the WPStart being flush mated with the WPEnd of the 2nd part - see image attached. In addition I would like to mate al the XZ planes in each of the parts fluch together and likewize the YZ planes.

Whenever I am using mirror command in assly . The mirrored part do not get constraint again I have to use the constraint or I have to make that part grounded.
View 4 Replies View RelatedI have used the derive component command to mirror parts many times but each time in the past I have had a desire for that part to be linked to the one I mirrored. I have a new situation where I would like to mirror a skeleton part file that I used on one assembly to make a new assembly.
For example, I used the part attached below to create a stair frame for a steel framed platform I am working on. It consists of geometry, work features, and sketches that represent the nosing line, guardrail, stair stringers, etc.
I have another stair on the other side of the platform that needs to be a mirror image of this one plus a few unique modifications. The new assembly cannot be "linked" to the other one as each of these assemblies needs to be modified independently.
How can I mirror this part to reuse work I have already done without having to create a new skeleton file from scratch? Using the derived part method, then breaking the link makes all of my sketch entities unconstrained.
How do I mirror a numbers of parts in an assembly.
There is a MIRROR icon but it's fuction is based on COPY.

Often times when I mirror a sheet metal part in an assembly, several problems occur: The material thickness (in sheet metal defaults) gets reset to the default
Example: My parts are .1875". I mirror one part in the assembly (creating a new part), then when I attempt to create a flat pattern for that part, it doesn't do it right because the thickness in the "Sheet Metal Defaults" is set to .125 (my template default). The "Use Thickness from Rule" check box is NOT checked in my template, but it checks itself when I mirror a part.
The mates completely disappear meaning I have to reconstrain the part.
I have two custom iProperties in my sheet metal template: LENGTH and WIDTH (each set to <SHEET METAL LENGTH> etc.). It retains WIDTH but loses LENGTH, so I have to go manually create a new custom property to get my LENGTH back.
Looking for views on what the best method is to copy a selection of parts in IV 2013 which will result in the copied selection to retain it's constraints ? I have an assembly which I have used the mirror method on a batch of parts, also used the standard copy method and pattern components.

I just recently installed Inventor 2012 and I'm finding it extremely annoying assembling parts together. I recall in 2011 I could see the parts interact and how the constraints would effect assemblies as I change offsets, relstionships, etc. But now in 2012 I can't see any of that until I acutallly apply the constrain and if it's wrong I have to back and edit it over multiple times till I get what I want. Is there anyway to get a preview of what will happen before I click the apply buton?

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 need to drive more than one constraint at a time. The assembly consist of a hydraulic ram that pulls a cable which is routed around a few pullys and then pulls another linear moving member. I don't really care about modeling the cable right now, I just want the cylinder piston and the final member to move in unison. I can only drive one constraint at a time, so I figured I could relate the two constraints together by setting them equal to a parameter (variable), but that isn't working. Is it me or is driving multiple constraints at a time something that would be very useful for a lot of applications?
View 3 Replies View RelatedI'm modeling cables running through a series of cable clamps. I'm working in an assembly with my structure as one part, clamps as seperate parts, and cables as separate parts. I modeled the clamps first and am using them to create my 3d spline to run the sweep. The clamps have moved several times and each time, the sweeps (cables) do not update to follow the new clamping path. I have tried multiple ways of solving this.
I've tried to redo the splines using "Include Geometry" and running the spline through the centers of the clamps. I've also deleted the constraints (which for some reason turn into fixed) and reapplied them as coincident constraints. However, once I setup these coincidences, they always change back to fixed.
In a last ditch method, I've created 2d sketches at EVERY clamping location (yes that's alot of sketches, time and effort) and projected the circular geometry to get a center point. This has seemed to work, but is so much work, there's no way we could use it regularly.
I have a VB program that auto updates the size of a door and frame assembly, and in turn, updates the shop drawings to reflect this change. I have a view on my shop drawing that I have drawn a sketch in. I start the sketch, add my dimensions, and I use 'Project Geometry' to project the edges of the actual part around the sketch to constrain my sketch and keep it in place. The problem is, as the program runs, and the door/frame changes height, the sketch loses it's dimensional references to the projected geometry. When I go back and reopen the drawing after running the program, all the dimensions that went to the projected geometry are gone.
Is there another way to anchor a sketch to a drawing view part instead of dimensioning to projected geometries? This doesn't seem to be working, and I've tried it every which way I can think of. Oddly enough, I have another sketch in a different view that is set up the same way, and it never misses a beat.
Why do we not have the "=" (equals) constraint option in 3D Sketch mode? It seems like a very basic need for a constraint. Is there a reason why one should NOT want to have an "equal" constraint in a 3D Sketch?
View 3 Replies View RelatedAll I need to do for now is to align one part to the center axis of another part. Later I will constrain but for now I just need to see where the two meet so I can project geometry onto a draw surface. So, all I need to do is make their central axes coincide on one straight line.
I can achieve the same result by counting the various lengths but I'm hoping there's a simpler solution.
Assume a beam like the one in the picture below.
How must I configure the constraints?
The left constraints should be a "Fix constraint" on the edge(not the face) I assume.
But the right constraints must not fix all DOF's.
How can I configure the right constraint?

View 1 Replies View RelatedIn the weldment of a crane boom i have different parts. Some are identical, but (1:1) mirrored.ipt. Then I merge them in the BOM in order to set the qty on "2" in the partslist.
Here the error occurs: in the "mass" field in the parts list says "varies".
This keeps me from generating a good partslist and the total mass of the weldment maybe messed up. I personally think it has something to do with the fact that the parts are sheetmetals. i.e when I look atthe Physical properties of the folded / unfolded (of the SAME .ipt) they differ in the same way i see in the BOM.
I've just installed 2012 and I seem to have a problem with constraints.
The basic problem is that the SHOW CONSTRAINTS command doesn't show the constraints for geometry that clearly has them. For example, if you delete a horizontal constraint from a line and then add a horizontal constraint to the same line, the line will be constrained but the constraint will not show up.
is it possible to copy and paste parts in an assembly but also keeping any constraints set on the part?
I.e. if I had a square block constrained to a flat face of a floor, when I copy and paste the block many times I would like all the copy blocks to still be constrained to the floor.
