i drew a cylindrical cam using the inventor tool then i also drew the actuator ( a simply plate rounded on top) but when i add the contact tangency link between the two surfaces and i move the cam , the two objects interpenetrate!
i'm using inventor professional 2012
modeling the actuator on a switch so when the cam rotates it moves the lever on the micro switch.

Is it possible to create a transition when the backplate shown in the picture is a cylinder?
I have tried several options, with 3Dpaths both nothing worked so far.

I need to model up a length of rod with a cylindrical end with a hole in it. The cylindrical end needs to be flattened slightly where the rod meets it. How to do this ? See attached picture.

I need to drawing something similar to the attached image on either side of a "U" shaped rod.
The "U" shape is drawn using a sweep of a circle (the hatched section on the atatched image illustrates).
I just can't fathom how to draw the solid at the top oneiter side.
I've been trying to add a plane at an angle, then draw a circle & try to sweep that for each half of the "u", but after a few hours, total fail
How can i get the length or diameter of a cylindrical face by selecting the face as shown in the attached picture.
View 4 Replies View RelatedIs it possible to show the deformed nature of a shaft after loading along its axis and simulation of the part. If you take as an example a rod of Plasticine and stretch it you will see the center section thinning,the same laws apply to a rod of steel during stretching,why is it that this is not shown during the
simulation of the part,is it mesh settings or something that is not built into the analysis. When one applies loadings to sheet metal the deformation is clearly shown.
I need to draw a cylindrical cam in Inventor Professional 2013. I tried using the cam module but it is not what I need. My cam can be generated by a third-degree polynomial. You could use the new "curve from equation"?
View 1 Replies View RelatedI'm trying to constrain the green cylinder to move between the red frame. The red cylinder is constrained on the surface of the larger gray cylinder, which moves around the grounded red frame. When the green cylinder goes up hill/down hill the larger gray cylinder is supposed to rotate around its own axis.
When I choose transitional constraint I'm only able to pick one face on the red frame, and not the whole face. I think it's because the face is not planar, but varies in z-led.
Neither am I able to use the Contact Solver, it seems like the friction is too high. The green cylinder doesn't slide that well when using Contact Solver.
I am really struggling in trying to revolve around cylindrical body on a specified angle. I understand the degrees of rotation angle, but i am looking to revolve or extrude a certain shape for the length of the shaft. Like trying to make a coil or a set of threads.
I have tried to use sweep but sweep doesn't work with two sweep lines.
Is there any way / trick to wrap a 2D sketch to a non-flat/cylindrical/conical face? See attached part. I'd like wrap the lines in Sketch2 to the ring's outer face in order to get a proper path for "engraving". I see no other way to get a proper path for sweep, because project along vector won't work.
View 2 Replies View RelatedI have just created a cylindrical object with an extrusion length of 300 mm and then created an assy(.iam). On to this cylinder i have placed a plate at right angles to the axis of the cylinder
What i wish to do now is mirror this plate.
It would appear the best way would be to create a work plane(mirror plane) thro the centre
Of the cylinder,however, how can this be done if when requested to create the plane 3 points are required,am i missing something here.
I'm currently detailing a part that's about one-third of a cylindrical piece (the part is lathed as a whole and cut into thirds). I'm trying to project the centerline onto the section view so I can ordinate dimension to it.
View 3 Replies View RelatedI want to find the intersection point between a cylindrical curve and faces in a body. I have the start point an start vector and a rotational velocity. With this values it should be possible to create this cylindrical curve.
Is there a function in inventor which I can use?
Currently I am using the function "FindUsingRay". But I thing that there is only the possibility to fire a linear function through the body.
Today I found the command "FindUsingVector":
Sub FindUsingVector(OriginPoint As Point, Direction As UnitVector, ObjectTypes As SelectionFilterEnum(), ByRef UseCylinder As [defaultvalue(-1)] Boolean, ByRef ProximityTolerance As [optional] VARIANT, ByRef VisibleObjectsOnly As [defaultvalue(-1)] Boolean, ByRef LocationPoints As [optional] VARIANT,
I did not find any information in the "Autodesk Programming help". what is the difference between this both functions?
Is the argument "UseCylinder" for a switch into cylindrical coordinate system?
In Solidworks I can emboss a sketch into a 'wavy' surface without difficulty.
If I try to do the same thing with Inventors 'Emboss' command It fails with "Only planar, cylindrical or conical faces are supported."
Surely there must be a way to achieve the same effect as in the first illustration, in Inventor ? Am I missing something obvious?
I'm trying to build an assembly with conical rollers rolling on a cylindrical support. Refer to the attached sketch. I'd like to be able to constrain the conical faces of the roller to the cylindrical surface of the support. It doesn't seem to be possible to do that in Inventor; or, more accurately, it's not possible to put a tangential constraint on both conical faces at the same time. The first tangential constraint causes the part to place a generatrix line parallel to the axis of the cylinder. (I had to look up what generatrix means, too.) So it's not possible to make the second tangential constraint.
How I can do this? Just in case that's not difficult enough, the reason I'm doing this is because, ultimately, the support will not be a plain cylinder but actually a tube that also curves. It's the behaviour of the roller through various curves on the support tube that I ultimately want to model, but I have no hope of doing that if I can't even get the roller constrained onto a plain cylinder.
Look at the attached snips. The assembly icon is strange to me. and I can not
set it as a contact set because it is greyed out. Is there any way to set this as a contact set?
Inventor 2012
Why is a part in an assembly not enabled for contact set? on right click the Contact Set option is grayed out, but that part was in contact set for another part already. i made some changes in the part, maybe that's the reason, is it?
View 3 Replies View RelatedAttached is a screen snipe of design that has a hydraulic cylinder in it. I've created contact sets for the rod and the cylinder however they keep breaking appart especially when I insert them into an assembly and drive to drive the constraints in a positional representation.
View 9 Replies View RelatedI'm working on a FEA of a climbing carabiner (oval-shaped; one side of the oval is a gate which opens and closes allowing a rope into the carabiner).
The gate of the 'biner has a hook which attaches to the "nose" of mainbody/biner. However, this hook does not engage until the biner slightly deforms.
I've attempted to use the separation/no sliding contact option, but the solver behaves as if there is no contact occuring. The nose simply passes right through the gate hook.
The initial gap of the system is about 0.040". That means the nose must deflect 0.040" before the contact surface comes into play.
I am using Invertor Dynamic Simulation and I need to know the 2D contact position data to be displayed in the output grapher (i.e. the x,y,z coordinates). Only the forces are computed in the output grapher. I’ve tried using the “trace” feature but this will not allow me trace the 2D contact point. It would even benefit me to know the angle of the normal force relative to the absolute frame.
View 2 Replies View RelatedI am trying to constrain motion for the following design:
-Object constrained to vertical motion (a counterweight).
-Object constrained to horizontal motion along a track (a slider).
A cable runs from the counterweight upward, makes a 180-degree turn around a pulley, runs back down, makes a 90-degree turn around another pulley, and connects to the slider.
When the weight moves down 10 cm, the slider needs to move laterally 10 cm.I don't care about modelling the cable, but I do need to have the slider move as the weight moves.
I will also need to model a case with a more complicated pulley, where when the weight moves down 10cm the slider moves laterally 5cm (again I don't care about the cable, just the relative motion).
Is there a way I can do this without creating a series of planes and cylinders and using rotation - translation constraints to link the motion of the weight to the slider?
I set the two v blocks were fixed and bonded contact type among three of them. The program said it was divided to three separated parts but i wouldn't expected that.
View 1 Replies View RelatedI'm trying to set up a sliding/no separation contact within and assembly for FEA purposes. I want to eliminate all moments (torque) between two pieces while still allowing one to impart force on another. When evaluating constraints, I'm seeing moments are infect being passed through. The guide mentions this contact for planer and cylindrical objects but makes no reference to spherical surfaces.
Is it possible to accomplish this type of a contact on spherical surfaces?
Can an adaptive part (non involved in the drive constraint animation) bother the contact solver?
I have an assembly, with only one adaptive part, i have activate contact set for other 3 parts (not the adaptive part), activated contact solver and drive the constraints, but in the animation contact solver doesn't work at all.
So, i have tried to move manually the assembly (suppressing angular drive constraint) and the contact solver works fine.If i suppress the adaptive part the driving constraint and contact solver work perfect.
So i wonder... adaptive part can annoying the contact solver functionality?
I would like to find a function that returns the two objects colliding using contact sets. I'm not sure this functionality is available in the API.

I had trouble uploading a screenshot of the part, awful drawing. Essentially the hole through the side of this crudely drawn cylinder is what I need to add. I am using AutoCad 2000.
I often use gradient cylindrical fill to paint pipes, however if gradient has to fill wide boundry it gets distorted, i found the way of making a short block and scaling it, gradient fill is consistent. It's ok but i want to make a dynamic block out of it and i cant, also if i explode this block gradient fill problem reappears (see pic)
Basicly i want similar looking hatch but without problem.
I have created a Hollow Cylinder using Polysoild (Object Option). I want to drill holes(array) on the cylinder.
