AutoCAD Inventor :: Using VBA To Constrain A Sketch
Jun 26, 2012I'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.

Dec 1, 2011How 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).

Oct 22, 2012I 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.
AutoCAD Inventor :: Ordinate Dim To Sketch Entities
Feb 20, 2012We're having a problem with Ordinate dimensions. When we dimension to a radius corner, we dim to the "implied intersection" of the two lines, rather than to the center of the radius. We make a sketch with the two "tick marks", then dim to the intersection of the tick marks.
Ordinate dimensions are not allowing us to pick the intersection: it wants to put two (or three) dimensions, one to each end of one or the other tick marks (see attached). We use Ordinate dims about once a year, but I'm sure I remember being able to ordinate dimension to the tick marks.

AutoCAD Inventor :: Only Allow Sketch Entities If Directly Associated To Extruded Feature
Aug 12, 2012I have a simple ipt file (attached)
It is a simple rectangular plate with 13 holes through on a pitch circle.
I have used a "circle" to construct the "Pitch Circle" and a "line" to construct the top dead centre of the circle.
I have then added a circle to use as a hole feature and used the circular pattern to make the holes equi-spaced around the circle.
This circle is then extruded "Through All".
My question is, How can I eliminate the construction "Circles" and "Lines" from the following code, only allowing sketch entites that are directly associated to an extruded feature to be accepted?

AutoCAD Inventor :: Shared Sketch Generates Sketch Doctor Error - Feature Suppressed
Sep 21, 2011I'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 RelatedAutoCAD Inventor :: Copy Part Sketch Into Drawing Sketch
Sep 20, 2012How 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.

AutoCAD Inventor :: Speeding Up Constrain Execution
Oct 19, 2012SO what is everyone say, trick about speeding up constrain execution. I have started working on this new project with 2013. And i'm finding myself losing alot of time. Basicly what i do is insert part from our database or content center and assemble them. So 80% of my activities on inventor are constraints. Right now i have this assemblies 175 / 156(small to me). And executing a constraint is minimum 4 seconds each time. If you consider that about 3 contraint is needed for each piece and final total part will probably be around 1000. i'm losing alot of time here
Yeah, i am not using preview. Why is inventor recalculating that much each time? Is it doing a rebuilt after each constraint?
What have you done that really increase the excution time of constraints?

Currently I am seeing the deflection of the shelf in the downward direction, but I do not see any indication of stress in the gasket behind.Currently the gasket is "bonded" to the steel tube the screws are bonded to the shelf bracket and the steel tube.
I put in "work axis" at the center line of the shelf bracket and the CL of the gasket, but I can't find a way to constrain to a work axis.The file is too large to upload here...
AutoCAD Inventor :: How To Constrain Movement In Slot
Jan 9, 2013I have one problem and I would like to get your opinion how I could solve this.
I can't share models I have problem with, but I made another with the same problem.
I have two parts - one with slot, another with "pin". How to constrain the "pin" to always move in slot?
I had some ideas but non of them worked for me:
1. Use the Transitional constrain came first in mind, but it gives unsuspected results in this situation. Pin part is jumping around and ends up contrained in another place ir should be.
2. Contact solver kind of do the job, but it works quite bad. I gives no control or accuracy (i can not control how much pin is moved out)
3. I even thought of point on 3d sketch constrain, but it can not be done
How you would suggest to constrain the movement? I hope I stated problem clear enough.
I attached model files. I use Inventor 2013
AutoCAD Inventor :: Constrain Component In A Track
Nov 25, 2012I'm trying to make a constraint allowing the dark smaller cylinder (1) to run in the copper track (2). I want the larger cylinder (3) to be able to rotate around its own axis, while everything is rotating around the Z axis. I've successfully constrained the parts so that all the parts can rotate around the Z-axis but when I constrain the smaller cylinder (1) with the tangent constraint with the track (2) the smaller cylinder is not able to move around on the face, it's just glued to the face.
I want the smaller cylinder (1) to recognize the copper faces as solids (so that it can't intersect the surfaces), this would allow the proper movement. I've attached an image of the parts.

AutoCAD Inventor :: Tangent Constrain On Multiple Curves
Aug 4, 2013Is it possible to have a tangent constrain on multiple curves?
see enclosed rough sketch, i would like the curved free end or the arm to be in constant contaced with the wavey top line on the other part, the wavey line is constructed as 3 curves but i can only get the tangent constrain to apply to one of the curves.
i would like the tangent constraignt to move between the curves so the part stays in constant contact with the wavey line. this is just a mess about sketch i suppose a real world instance will be a wheel following a shaped cam plate.
