I want to creat a driven dimension that I can use as a reference dimension in another part. Is there an easy way to do this without creating a new sketch, going into a previous sketch, making a long function based on other dimensions, etc.? For instance, just like the measure tool, but it stores the measurement.
View 4 RepliesIn 2012 when in a sketch in an assembly all the stuff under "Format" is grayed out.
You cannot make a dimension driven, nor can you make a line construction or a centerline and you can't change a sketch point into a center point. Do I have some setting wrong?
I have one problem in ilogic "How to convert the normal dimension to driven dimension through ilogic"

View 5 Replies View RelatedI have an assembly I've put together in Inventor 2011. I tried to make an adaptive spring to use with a shock that goes in a car. I'd like the spring to change size as the shock extends and contracts.
I went through the process of creating an adaptive spring, and it worked, but I could only change the length of the spring by using the "Drive Constraint" feature, which only allows me to adjust the spring when I'm using the "Drive Constraint" menu. It plays like a movie. What I want is a part that just moves like you would expect when you push/pull the ends of the shock. I don't want to have to drive it like a movie.
So then I thought that I could just simulate a spring by making a series of rings (toroids). I could constrain the bottom ring and top ring to the shock geometry and then have the other rings position themselves according to the distance between the top and bottom rings.
SO, I have 5 rings. The bottom ring is grounded the top ring has a Limit Constraint that sets the top ring anywhere between 3 and 7 inches above the bottom ring.
How do I create a driven dimension on an assembly that will automatically update the distance between the top and bottom ring?
I would like to call that dimension "HEIGHT", and then I could use parameters to set the middle ring a distance (HEIGHT/2) above the bottom ring, I could set the ring below the middle to (HEIGHT/4), and I could set the ring above the middle to (HEIGHT*3/4).
I should then be able to move the upper ring up and down and the other rings reposition themselves automatically to keep even spacing between the rings on either side.
I tried making a sketch in the assembly and using the "Project Geometry" function to add the location of the upper and lower rings to the sketch. I then used the "Dimension" function to create a driven dimension between the upper and lower rings. When I finished the sketch the other rings all updated exactly as anticipated, but when I moved the top ring the projected outline did NOT move, so the other rings did not continue to update.
lease do NOT link me to adaptive coil video tutorials or explain how driven dimensions work when making parts. I am not looking for that, I am looking for how to create driven dimensions between two placed components in an ASSEMBLY.
I have a driven dimension in the attached part. If I change something in the part that affects the dimension it won't update unless I double click it to get the edit dimension dialog and then confirm it.
Changing the contour flange's length will affect the driven dimension which can be found in sketch5 under cut1.
Is there anyway to add a driven dimension or reference dimension as a column chooser? What I am really trying to accomplish is to show the metric and english dimension in my general table for my ipart. I model itself is dimensioned in metric. I now would like to add the english dimension next to the metric one.

After I apply a driven arc length dimension to a fully constrained sketch and then put user dimension in a user parameter I get an error when I rebuild the part. The error states the the dimension can not be solved.

View 2 Replies View RelatedSeen this recently? Using Inventor 2012 SP1 on Windows 7, 64 bit. If we go back into a previously created sketch and edit or add a dimension, upon clicking the green check mark to complete the dimension edit, the sketch exits back to the modelling environment, meaning we have to edit the sketch again to continue with other changes. Obviously no big deal if I'm only editing one dimension, but how often does that happen?
This started happening prior to SP1 being installed. We have this happening on multiple computers (all with the same hardware specs) in our office. I don't believe it to be a hardware or driver issue, but I am wondering if it is a process issue. For example, we use project geometry a lot, even projecting from other parts within an assembly (non-adaptively). We also work on SAT file models, rather than geometry initially created from Inventor itself.

I have a part.I use some Parameters of this part as linked to other parts.Once I change any parameter used as linked the other parts will follow it automatically.So I have drive and driven parts.
Now for some reason I need to change some geometry in my drive part in the way my drive dimension must be reattached to other geometry points.
I cannot delete and create the new dimension even with the same name since all my driven parts will lose this linked parameter in either way and this parameter becomes static (Reference Parameter).
I wish I can preserve the existing dimension (parameter) and reattach it to other geometry.
I am trying to apply dimension constraint for circle to add the radius dimension.
I have given the dimension location text point as input, but it doesn't take input location point to place the dimension and places the dimension at the center of circle. Please see the attached snap "CircleWithRadius.png".
Here is the sample
//===============================
CComPtr<Point2d> point2D;
TransientGeometry::CreatePoint2d(5, 5, &point2D);
CComPtr<SketchPoint> sketchPoint = SketchPoints::MethodAdd(point2D, FALSE);
CComPtr<SketchCircle> sketchCircle = SketchCircles::MethodAddByCenterRadius(sketchPoint, 3);
[Code] ........
Why the circle entity always place the radius at the center of circle?
I have created a SketchLine entity and trying to add aligned dimension by calling DimensionConstraints::AddTwoPointDistance(). It adds the dimension with inside arrowhead (see attached CurrentWorking.jpg), however, it would be nice if the dimension is added with outside arrowhead (see attached Expected.jpg).
if there is any API to toggle the dimension arrowhead accordingly.
How does one (in sketch mode) dimension from the quad of a circle instead of the center? Been dealing with it for a long time, no I am fed up and want to dimension from the quad.
View 6 Replies View RelatedI am having trouble changing the dimension text size of any 2d or 3d sketch..
the default has changed for some reason (i might have accidentally changed it while looking for something the other day) but i need to know how to change it back.. I can't do anything without a dimension getting in the way!
This is the first I've noticed this, but a sketch in an assembly does not allow to show the dimensions as an expression? In a .ipt sketch you can right click and the pop-up menu has an option to show the dimensions in different forms. I do not get this in an assembly sketch.
I do not know if this is me or not. It's just curious that it does not do that.
I need to disable the "Set sketch scale by the first dimension" feature.
The feature is nice under normal circumstances, but in my case i need to insert a dxf sketch and then draw around it in inventor. When i start to dimensioning the sketch then it scales the inserted part.
That aint so good.

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 the heck does Inventor arbitrarily orient sketches as it sees fit? I often create my first sketch on the right (YZ) plane and Inventor, stupidly turns the sketch where "RIGHT" in the viewcube reads from top to bottom.
I know all the things to do to AFTER this happens, but it shouldn't happen in the first place. If I turn my sketch so that up is up, like it should be, I then have to remember that vertical is horizontal, which is now vertical. I can't change the sketch coordinate system. It's the first sketch and there is nothing to align it to.
How to prevent the above example from occurring in the first place.
This, and the fact that I can't dimension to any existing vertices or edges without projecting them first, really make me hate using Inventor sometimes. To me, these are huge problems, neither of which Solidworks has. At worst, both of these behaviors should be configurable.

If my memory serves correctly CATIA used to have a feature pattern type that allowed for the selection of two sketches (or something along these lines, my memory is fuzzy). One sketch contained the feature profile, and the other contained points where you wanted the patterned features to plop out at. Is there any similar function in IV?
In case there's another way to accomplish what I'm trying to do, I'm drawing a piece of roll formed sheetmetal with a crap load of slots with non-uniform spacing. I would really prefer to not have to create a sketch and draw all these slots. Especially when there's not even a legitimate slot command. I could probably draw one and then copy it around a bunch of times,
I would like a part, that if i place it into an assembly, that it asks for a parameter (for example the length).Parts in the content center have this featere (for example tubes). I think this has to do with the driven length in the content center.
How do i create a driven length?

View 3 Replies View RelatedI have a parent assembly that contains multiple sub assemblies, two of which need to synchronize with each other.In the parent assembly, I have created a user form that controls the sizes and quantities of all the different sub assemblies.
Sub assembly 1 contains a bracket for supporting 4 rows of pipes.Based on the width selected from the main parent assembly, the length of this bracket can vary.
The spacing of the 4 mounting positions is also determined from the length of the bracket.Sub assembly 2 is an assembly containing all the pipes.The pipes are spaced apart to suit the bracket using a component pattern, and it is this distance that I want to control from the parent assembly.This is just one of the basic scripts I've tried.
Pipe_Spacing=Parameter("SubAssembly1:1", "Pipe_Spacing_A")
Parameter("Piping assembly:1", "Pipe_Spacing_B")=Pipe_Spacing
Pipe_Spacing_A is the spacing of the bracket
Pipe_Spacing_B is the component pattern in the piping assembly
Pipe_Spacing is the parameter in the parent assembly to be driven by the bracket parameters.
I have very little iLogic experience & have being learning as I go along with this project.My best guess is that the code can't loop back on itself. On a slightly different note, I have also noticed that the sub assemblies don't update properly.
If I adjust the width to X and regenerate the model, some of the sub assembly updates. To fully update, I have to go back into the user form, change the size to Y & then change it back again to X and then regenerate.
I've created a shared sketch and have used it with various features. Sometime those features are suppressed. The model works fine but the shared sketch generates a sketch doctor error because the feature that created it has been suppressed. Is there anyway to make the sketch suppressed so it doesn't trigger a sketch doctor error? Inventor 2013
