AutoCAD Inventor :: Tangent Constrain On Multiple Curves
Aug 4, 2013
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.
Is there a way to use the curve driven (rectangular) pattern referencing two tangent curves (an arc and a tangent line). I'd like to be able to create this pattern of slots in one pattern, otherwise I'll have to make two cut features at each end and use one pattern for the straight and another for the curve.
I have created a bin/vat/tub using sheet metal. I started with a contour flange. I then copied the sketch and pasted into a new sketch off the flange for a contour roll feature. Then a flange, roll, flange, roll, flange and roll. My trouble starts at the last flange. I'm trying to construct the flange exactly as I have created the features before. I set the distance, select the profile (it shows the flange on the screen), hit apply and that's when my message shows up. "Non-tangent curves found in path: flat pattern cannot be correctly created. Edit sketch and add constraints to the curves. The sketch is fully constrained according to the lower right hand corner and the auto constrain button.
I am used to drafting surveys using Eagle Point Coordinate Geometry & Boundary Survey & I am now moving over to C3D, & I am trying to reproduce a boundary survey in C3D 2010, when it comes to Tangent & Non Tangent curves there does not appear to be any routine that allows you to create them in logical sequence or otherwise from the geometrical info provided on paper maps i.e. Radius, Delta Angle & Length, are there any survey techs on here that have been able to resolve this issue?
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 created a horizontal alignment from objects and upon importing it c3d seems to have taken liberty to arrange the lines in order it sees fit. Is there a way to rearrange the alignment tangent and curves and change their direction?

How to curve a piece of sheet metal over the outside curved edge of the attached part. I can do it the old fashioned way but was wondering if it could be done in sheet metal which would give me the flat pack automatically (that way there is less chance for errors). There are several of these baffles joined together by a spine and the sheetmetal will eventually go over all of these, and have a few modifications to shape the end profile.
The outer curve is a spline which has changing radius and hence to use a contoured roll would be rather difficult and time consuming (there are also some flat sections at each end of the curves as well).
Autodesk Inventor Professional Student 2013 is the version I'm using.
This is probably a simple one, but when I dimension from an edge to the tangent of a radius or circle. It always snaps to the center. How do I get the dimension to snap to the tangent point?
I am still making some adjustments to our standard drawing template and I ran into another issue..
I want the tangent edges to be displayed automatically when I insert a drawing view rather than clicking the Display Options tab and checking the Tangent Edges box every time I make a new drawing. Is this possible? If so, how?
I tried inserting a view, checking the Tangent Edges box, then deleting my view and re-saving the template but it still went back to the default.
I have a roller pin which follows a certain path using transitional constrain in an assembly. A box is attached to the roller pin which move along with it. My problem is that I want one face of the box to be tangent to the path which the roller pin is following so that the box moves according when it is on the curve. I have attached the file with the message.
I am trying to place a tubes cylindrical surface to another tubes cylindrical surface using add constraint. How do I specify which side of the target surface to apply the constraint ?
Since switching over to Inventor 2012 I have been having trouble snapping to tangent points on a curve or circle to pull dimensions. I would do it manually but if the dimension is not referencing a specific point in the model it turns pink to identify an error.
Is there a setting that may be not allowing me to snap to tangent points?
I am having trouble with a part that I am working on. Trying to trim to the tangent edge. I cant post the part that I am actually using, but here is an example of a similar problem. In the attached file, open the "Negative Part.ipt". The sketch 2 contains a line (unconstrained). I need this line to be tangent with the curve below it.
I can project the edge of the curve to my sketch plane, but not the tangent of the radius.
Looking at a side profile of a channel in a drawing, you will usually see a top and bottom edge, as well as some nominal flange thickness.
In Inventor, all you see is the top and bottom edge...because the channel's shape is really radiused on the flange.
So I turn on "Tangent Edges" in the Display Options of my view...now I see three lines representing the flange. I can manually hide the other lines, but this option creates a TON of lines in my views that I would have to manually hide.
What is the quickest and cleanest way to represent a channel without seeing a ton of extra tangent lines?
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.
How can I create a workplane with the API that is tangent to a surface and passes thru a workpoint. It is easy to create a work plane of type kPointAndTangentWorkPlaneDefObject by point and click in Inventor 11, but I can't figure out how to do it in the API.
I'm designing a part, and am having trouble creating a plane tangent to a curved surface. One option for creating a plane says "Tangent to Surface through Point", which in theory I should be able to use, but I can't figure out how to actually place a point there before in order to create a surface at the point.
Basically I am trying to cut a circle into the curved right side of the part
Is there any way to have Tangent Edges to show within all view's created on my idw automatically within the my template file or do I have to remember to double click on each of my created views per page, select display options and make sure Tangent Edges are checked on.

I used Solid Edge for my entire professional career. One thing that is driving me batty is how, when necessary in a view for clarity, tangent lines are displayed and how to change them, or at the very least, come up with a work around to display them how is needed. In general, tangent lines are first, supposed to be of thinner lineweight, but also, are not supposed to extend all the way across the surface of a part, they are to leave a small gap.
I have found and tried the option of displaying tangent lines, and also have checked the for shorten option. The issue is, in many of the parts the gap produced in HUGE. So I've spent a few hours tinkering, and I finally decided to try and define a new linetype using autocad express tools. So I tried this, but to my dismay I haven't been able to set up a linetype that only has a gap at the end. See attached jpeg for illustration.
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.
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).
