AutoCAD Inventor :: How To Constrain A Face To A Cylinder
Feb 28, 2013
I am trying to CAD a model rocket I just made so I can test the aerodynamics of it. I have all of the individual parts made in inventor, but I am having trouble getting the fins on the rocket.
How can I constrain the fins (which have a flat face) to the outside of the cylindrical rocket tube? The photo shows the fin and the face (the narrow and long face) that I am trying to constrain to the tube.
In inventor 2013 I want to extrude a horizontal circle on surface of a bigger vertical hollow cylinder. but what i did it enters into cylinder, and i only want to extrude it on external surface.
I have a high res model and Im building a low res one on top of it. I'm trying to constrain the movement of a vertex of the low res model to the surface of the high res model. How can I do that in Max 2012?
All I need to do is merge a circular face to a flat face, so both faces become one continuous face. Is this possible at all?
I have a attached a screenshot to show what I mean. Face 1 needs to be merged with face 2. This is so if I constrain anything to that face it will constrain to the entire face and not either the circular face OR the flat face.
I'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.

I've made 2 parts and I'm attempting to constrain them but I can't seem to get it to fit properly.The transition should fit at the opposite end of the 2 square cutouts with the square end of the transition inside the cylinder.
SO 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?

I am trying to determine how to properley constrain the assembly below, so that the compression of the rubber gasket will be properly indicated.
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...
I 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'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.
How 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).
Is 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.
I 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 have an assembly with a curved line made in a sketch, and a part with a point in the bottom.
I want to constrain the point to the curved line, but the regular Constrain options wont let me do so.
I am making an animation with Inventor Studio, so I need this constrain, so I later on in studio can manipulate it and insert the first part into the other.
How you constrain a section view so that is perpendicular to an axis. See "SECTION B" on the attached drawing for an example of what I am attempting. I have created the view but cannot make (constrain) the view perpendicular to the slot that is orientated at 30 degrees from the vertical centre line. I have lined up the view by eye so it looks close but it's obviously it's not accurate.

After installing the cloud-optimization-upgrade for subscription customers I cant export video from "drive constraint".I click the "record" button, I choose the name and quality of the video and when i then return to the "drive constraint dialog box" I get an error message "The file constraint.wmv could not be opened".
I have tried different names, storage locations and different video-quality but nothing changes.I successfully performed the same video creation just before the upgrade with the same assembly file so I know that its not the file.
Lets say we have a plate with 100 randomly placed holes on it and 100 parts to attach to those holes. The parts aren't content center parts so they can't inserted in an easy fashion and the random hole spacing makes component pattern useless. The parts would normally be constrained using the insert command and you'd have to do all 100 separately. Would it be possible to make a script that would let you select the 100 parts then choose the selected geometry on one part and then a hole on the plate. It would apply that insert constraint and automatically select the same geometry on another part so you could simply select another hole. Then rinse and repeat until all the parts have been constrained to holes on the plate.
If something like that is possible it'd cut down the number of clicks greatly and also panning/rotating to select the different parts and holes on the plate. This isn't a daily thing we'd be doing, but it comes up enough in large assemblies it could be very useful. I haven't done any scripting for things inside parts/assemblies so I don't know what's possible while scripting.
I want to transfer the rotation motion of part 'C' at a pivot point 'D' , to part 'E' which is pivoted at 'F', while the flat surface of the part 'c' is inserted in to hole 'B' of part E. How to give an assembly constrain to hole 'B' with flat surface 'A'
For some reason it will not let me constrain a part to the center of gravity plains. I would like to constrain lifting lugs to the center of gravity so the model will automatically update itself. Is there anyway to make this work (using ilogic or anything)?
Why would Inventor tease me with showing me the center of gravity plains in an assembly but making them completely useless?
I just set up an angle constrain with min and max values (explicit vector) and when I grab and move the part inv will crash, it happened 2 times after restart too...

I need to emboss ( cut in ) some grooves into a cylinder, but in such a way, so that they won't get narrower. What do you think would be the best way to do that?
I have made a sheet metal cylinder with a rip. I am trying to create a seam on this rip as is done in [URL] ....... about half way through.
I have tried to go through the same steps, but I can not select the inside of the rip to built hems and flanges on. I also tried to make the cylinder by sketching 350 degrees of the cylinder instead of creating a rip, This had the same problem.
Why I can't select these edges or how I can work around it?
How can I create a rib that touches a plane and the end of a cylinder? Inventor will not do it since the thickness of the rib does not touch the cylinder (see attachment).
