When you're working on a sketch in the part environment the status bar shows the number of constraints needed to fully constrain the sketch. For example "2 Dimensions Needed".
How do you retrieve this value using Visual Basic Net?
In Auto desk inventor how to check assy was fully constrain and whick comand to use to check ?
View 4 Replies View RelatedI made this sketch and the two marked dimensions were added when i pressed the Automatic Dimension and Constraints tool, because, in spite of all the dimensions i put manually, the sketch wasn't fully constrained.
Why wasn't it? it seems to me that i gave all the necessary information.
It seems there is a problem with Inventor 3D Sketching. I have a 3D Sketch, with 1 fully constrained vertical line, and another vertical line with an open length. I then join the 2 lines with a line on the top. When I give the top line an angle dimension, I expect it to be fully constrained, but it appears not as the line remains "green".

I'm having trouble extruding a fully constrained sketch. The sketch is a cross-section of a hollow cylinder that is splined on the inside surface (see attached part file). The line segments that create these splines seem to be grouped together because moving one line moves the others, however the sketch will not extrude.
I can't use the coincident constraint button to group the lines because they don't separate from each other. I also tried to use the close loop button but was unable to select all the necessary lines.
how I can extrude this sketch or make an equivalent sketch that is easier to extrude
I am trying to constrain a point(on a different part) to the sketch(yellow) on the inside surface of the triangle part. If I try the constraint like how it is now, it only allows me to select one segment, not the entire triangular shaped line. It would work if inventor saw the sketch as one single element, but it of course does not. I tried making a 3d sketch of the inner surface and then constraining to that, but it did not work.
View 3 Replies View RelatedI've managed to hack together some code to draw a rectangle and dimension it. Now I want to constrain it to the origin. I figure either using two dimensions from a top/side to the origin and setting the dimension as half of the other respective dimension would work. Or constraining the center point of a top/side line to be vertical/horizontal to the origin.
The problem I'm having is I do not know how to reference the origin. So until I figure out how to reference the origin point I can't use either method.

How to become able to fully constrain a sketch with an image in it? Always stalls at 1 dimension required. Try a sketch with only an imported image.
View 2 Replies View RelatedHow is this accomplished in Inventor? The 3D sketch environment seems intentionally crippled. Many of the constrains are not available, and the "include geometery" command refuses to include the origin (or any other planes and axis for that matter).

View 2 Replies View RelatedWhy 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 RelatedI have a sketch that Inventor changes its status between under constrained, over constrained, and fully constrained depending on dimensions (makes sense), and wether I rebuild the model (WTF?).
Steps to reproduce:
1) Open the attached .ipt file.
2) Examine Sketch11 (under Face3) It should be fully constrained.
3) Exit the sketch. Open the parameters dialog and change the value of "angle" from 45 to 60. (If you get an error message change it to 50 first, then 60. It's a work in progress.)
4) Re-examine Sketch11. It is now under constrained.
5) Exit the skecth and go to the manage tab. Click "Rebuild All".
6) Re-examine Sketch11. It is now fully constrained.
7) Scratch your head and post back with your theory.
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.
Does Inventor (2012) have the option to view sketch constraints as a list? I feel like I am playing pictionary trying to find out what constraint is what and what it is constraining and it doesn't work that Inventor stacks anything nearby on top of each other.
I've attached a file showing what the problem is, please don't judge the model tree. I was prototyping as I went so it is messy.
I made a bunch of lines, then used the bend command to make curves where they intersected. I'm trying to put lines connecting A to C and B to D. How do I constrain the ends of the lines to the center of the curves?
View 9 Replies View RelatedWhen I add a text to a sketch, I can constrain the rectangle to set its size, orientation and position.And I can set the text width to fit into the rectangle. But I wasn't able to set the text height to fit into the rectangle.
Am I missing something or is the fit text option doing only half the job?
One of my frustrations with Inventor is the difficulty of constraining a sketch so that the solution is unique. It is an issue when alternate solutions appear while making adjustments.
As a simple example, suppose we have an adaptive work point. This point can be solved to be at a distance L from the origin, but could be in any direction meaning the part can rotate freely.
Instead of a work point, consider using an adaptive sketch point constrained vertically from the origin. When solved at a distance L from the origin, the part can rotate around the vertical axis (as one might expect when fixing two points), but it can also be flipped with the sketch point located in either the positive or negative vertical direction. Is there a way to ensure a solution is only found in the positive vertical direction?
Do you know how to constrain 2d cad sketch to match existing 3D model. see screenshot. Is it doable?
View 6 Replies View RelatedI use 3D sketching frequently as a means to generate frames with the frame generator.
I notice that the constrain group no longer contains an equal length tool, as in a simple 2D sketch. This is where i would generally select two lines, and constrain them to be equal in length.
Is there a reason for this omission? Should I be worried that my menus are not showing the full options for constraints?
I cannot select origin to constrain sketch with dimension to origin?
I selected Sketch,
expanded origin,
selected mywork plan (xy)
drew rectangle,
input dims,
right click for marking menu,
selected dimensions,
Origin is yellow,
cannot select it and then edge of rect to set dim that will center sketch on origin? Just like the videos show, but cannot select origin>
Being all new and complete virgin-like, to ilogic, I would like to know wether it is possible to analyze a sketch (wenn it is being closed)?
What I want to analyze is:
Does the sketch contain a fully constrained closed loop?
Does this closed loop consist only of straight lines?
What is the total number of lines in the loop?
Next fase is:
Create an excel-sheet with the following information:
For each line in this closed loop i wish to add the length of the line, and the angle to the next line (consequently on the internal side of the loop, resulting in angles from 0 to 180 degrees).
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 some assemblies that are made of iLogic parts. The code within the assemblies causes a common external rule to run in each of the parts to update the part's metadata (descriptions, part numbers ect.) to relect any changes to the part.
However, when a change is made to the assembly, not all the parts are effected and yet my code will still run the external rule within the uneffected parts. This slows things down some, but more problematic is the fact that the uneffected parts need to be checked out/revised, even though they themselves haven't changed.
Is there a way of reorganising my code so that external rules are only run in parts that are effected by the assembly change?
I have a simple sheet metal part that does not require explicit bend radii. We leave it up to the shop to fab this part up as long as it's final outcome is within tolerance. We don't normally include a flat pattern, simply because it could cause confusion when cutting a blank. I use the default bend allowance and bend radius, which gives the exact blank size and bend locations. But our local fab shop probably doesn't/won't use the correct tooling to provide the exact bend radius, so this will throw off the final outcome if the blank was cut using the flat pattern dimensions.
I can apply the flat pattern to my drawings, because there is some sheet metal components we have that require the flat pattern to show cut profile features.
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

View 2 Replies View RelatedHow do I duplicate the 2D line work from a part level sketch into a drawing level (overlay) sketch?
I started a simple 2D piping system diagram sketch by opening a new part file and using a sketch to stick draw the system schematic including some annotations. Then I opened a new drawing file and made a base view of the part file to bring a view of the original sketch into the drawing.
I realize now that it would have been much easier to have created the schematic directly in a 2D sketch at the drawing level, which would have made editing the annotations much easier at the drawing level, and there is really no need for the part file to exist. I have no intention of creating a 3D model or "real" part in the .ipt file, was just using it as a jumping off point to sketch.
I was thinking that I could correct my error in judgment by just copying the sketch and pasting it into a new sketch on the drawing, but it doesn't want to work that way. I have tried copying both the whole sketch at the browser level, and the entire sketch contents (all of the lines and annotations) from the opened part sketch, but when I attempt to paste either of those into the drawing, paste does not seem to be an option. I'd rather not have to draw the whole thing again, as in typical fashion, my once simple sketch has grown in proportion and complexity from its simple beginning.
I was trying to query some sketch points data from a profile Path using code as below. However the program stopped without telling the reason.
Code below:
i = 0;
foreach (ProfileEntity oSourceProfileEntity in oProfilePath) { switch (oProfilePath[i].SketchEntity.Type) { case ObjectTypeEnum.kSketchArcObject: { SketchArc srcSkArc = default(SketchArc); srcSkArc = (SketchArc) oSourceProfileEntity.SketchEntity; // error points[i] = srcSkArc.StartSketchPoint.Geometry; break; } default: { SketchLine srcSkLine = default(SketchLine); srcSkLine =(SketchLine) oProfilePath[i].SketchEntity; // error points[i] = srcSkLine.StartSketchPoint.Geometry; break; } } i++; }
First we imported an ".igs" file to inventor, which produced "wires". Then by promoting the wires it produced a 3-d sketch.
The model is in one plane and 2-D, and we are trying to use Ansys 2-D analysis, but in-order to do so it needs to be in a 2-D sketch.
The model is too large to be redrawn on a 2-D plane, how to convert it to a 2-D sketch
