My goal is to let some wheels roll in a path which exist from 2 straight paths and a corner. I can constrain them to 1 path at a time but not to all of them so my wheel makes a corner. I
You can find the guide rail as attachment. There is a path in the sketch from which i sweeped my form but he divides it in the 3 parts so i can't constrain the center point of my wheel to this path.
I am trying to simulate the path of ropes through pulleys/sheaves etc. It's a bit of a chicken-and-egg set up.
My workflow is the following:
Assemble and constrain geometry
Create plane in assembly than rope will run on.
Create in-place part (rope) with box ticked for "constrain to sketch plane" or the like, referencing above geometry.
Question 1: I see my in-place component is not constrained to referenced geometry, I can drag it around?
I then ground it or constrain to workpoints used as part of the original "project geometry".
I then alter the original geometry and...nothing!
Question 2: How do I get my rope to adapt?
Attached is a mock up - original contains assemblies within assemblies etc. The base has been altered after creating the in-place parts, and the rope has not followed suite.

View 9 Replies View RelatedI'm doing an offset path command on a random shape and I need to repeat that in 4mm increments. I noticed that this command is far from accurate. To be as precise as possible I copy the base shape, paste it in front, apply the offset path command +4mm, +8mm etc (since the shape has round edges I chose round and a miter of 5000), and expand appearance. However, at 8mm expansion the round curves become pointy curves and therefore not mimicking the original shape.

When I rotate the drive shaft gear very slowly, the assembly follows the the correct motion path, (figure 1), however, when I rotate it quickly, the assembly snaps the linkages to an orientation that is not physically possible, but satisfies the geometrical constraints (figure 2). I can't use contact solver because I am using the adaptive function for my sub-assembly to avoid having to re-constrain many parts.

View 9 Replies View RelatedI'm just getting started using the Tube and Pipe environment for some of my work, and I've got what I'm hoping is a simple question with a simple answer. In the picture attached I've got a 1" pipe dropping down into a 8" pipe which I've disabled because it's a standard part right now and I want to replace it with a tube & pipe run. The thing I seem to have the hardest time doing when routing my pipes is aligning/offsetting my nodes with existing geometry in the assembly. In this case I want the end of the 8" pipe to be 12" offset from the centerline of the 1" pipe, and for the 8" pipe's centerline to be 12" below the bottom of the mezzanine's I-beam (as the standard part it is now). What's the best way to do this in the Tube and Pipe environment?
I tried "Include Geometry" from the "Create" panel but that only lets me create planes, which won't work with offsetting from the 1" centerline. However, SOMETIMES (it's a big sometimes) ALL of the options in the "3D Sketch" tab are available. When that's the case, I can go to the "3D Model" tab and create workpoints, axes, and planes. Sometimes, though, they're not all available, and I'm not able to place anything but planes. How I can change it so I can always use all the geometry of my assembly?
Also I'd like to know if constraing fittings and point-snapping routes to my assembly geometry in this way is the best way to do Tube and Pipe routes. Will doing this allow my routes to update if the assembly changes?
I am assembling a weldment and need to place a looped bar onto a tubular stanchion 50mm below the top of the stanchion. I have made axis at each point on the stanchion and the bar, but i cant figure out how to constrain the loop to the point I require. All I can get it to do it to constrain to the centre of the stanchion only.

The opposite end of the transfer is tangentlly constrained to a latching mechanism. When the latching mechanism is lifted, the transfer rotates slightly around a screw (made invisible) and the spring is flexed. When the latch is released, the spring returns the latch to the closed position. I have several other assemblies that use the same principal, but some with just a piece of mild steel used as a cover as well as a spring.

View 2 Replies View RelatedI am trying to make a 3D sketch that is constrained to two different parts in an assembly. I want the sketch to be constrained to each of these parts so that if you move the parts relative to each other the sketch will adapt.
I have tried using work planes and project geometry but when I go to move the part the geometry won't always follow the part. I am using a spline for the 3D sketch so it should be able to adapt when the parts are moved but the problem is constraining it to something that follows the part.

View 9 Replies View RelatedI am trying to make a robot chassis in inventor using vex parts. I have a full library of vex parts. I have my basic chassis constrained but for some reason when i use the move command the parts still move, but then snap back into place.
Also, after giving up on the moving chassis i tried to move onto bearing flats. Bearing flats consist of 3 holes in a line that match up with the holes in the chassis rails. I constrain the face of the bearing flat to the face of the chassis rail. This constraint works and removes a degree of freedom. However, when i try to remove the other 2 degrees of freedom they dont seem to go away. I use the tangent constraint, constraining the hole of the bearing flat to the hole of the chassis rail(which is square) using an offset to make the hole centered. I constrain in both of my remaining degrees of freedom, but they bearing flat still moves.
I have a vector drawing of a logo, currently in adobe illustrator format. I'd like to create a 2D sketch in Autodesk Inventor and then insert this drawing into the sketch as a shape that can only be placed and scaled.
The way I'd expect this to work is essentially that I'd get a rectangle X enclosing vector object Y, and that I'd then be able to create a fully constrained Inventor sketch by simply constraining the corners of this rectangle X. Is it possible to do something along those lines, and if so what is the best practice for it?
What I tried, which failed, was this:
1. Converted the AI file to a .DWG file
2. Used the "Insert ACAD" command to place the file in Inventor with the Constrain End Points and Apply geometric constraints boxes checked (other boxes were unchecked)
3. Waited for a surprisingly long time for this operation to complete, maybe 30s on a 16GB 2.6GHz quad machine
The result of this operation is that I now see my imported geometry, BUT all vectors are treated as individual shapes and I have 2637 dimensions needed.

View 5 Replies View RelatedI have an oddly shaped flat plate extruded from a sketch, the sketch of which has lots on constructions lines, none of which actually represent solid edges of the plate. However, I want to locate the plate to other components via the geometry defined in the sketch.
I find that when I am trying to constrain the plate to other parts none of the sketch geometry is available to me. Points, lines, construction lines, circles; I can select none of it when constraining. I am confused. How can I constrain such a part?
Just to clarify - the flat plate is the base of a structure. Its profile is decoratively shaped, so nothing about the cut edge of the plate is suitable for constraining to. I need to constrain off geometry defined in the sketch.

I'd like to create custom effects using paths. Is it possible to distort a (rectangle) area along a given path? Let's suppose for instance I have a gradient in a rectangle area and I drew an open path manually with a few nodes forming waves, loops; I'd like to have the rectangle area "follow" the path and be distorted accordingly. Mathematically that would suppose:the rectangle area would be stretched to fit the path length andthe rectangle area could be "bent" using its gravity centre as a reference point. That'd be useful for creating smoke effects for instance. Can Gimp 2.6 do this or is there a plugin?

View 10 Replies View RelatedWhy is it that when you create the first constraint between any two components, the secondary component moves not only to satisfy the constraint, but also in ways that have nothing to do with the constraint. This is not occasional behavior, it happens every time.
I always have to stop and move the secondary component back out of the way to get to the other features I need to reference to continue.
How do you fully ground & constrain Tube & Pipe Routes?
The problem I have is after I complete My runs & routes & I have to make a dimension change in my Route, my route does not stay vertical & horizontal, then I have to start all over, which is very time consuming
I'm sure there is a way to do this , just like in a regular sketch, you want all of your lines to turn purple so it is fully constrained , well with the routes they are not, only the very first line then the rest of the lines in the route are blue. I have tried to use regular constraints but I get the error message saying constraint already applied.
I have also tried to ground a work point from where the route starts from, & that didn't work.
I'm really struggling with constraining a weldment assembly. I've attached a JPG of the Assembly but I cant get the constrains to go where I want them.
Basically this assembly is a wheel with three equally spaced stays welded to a large nut hub. I have constrained the center axis of the wheel to the center axis of the Nut so the wheel and nut will remain aligned.
What I'm struggling with is constraining the three stays to the wheel and to the nut equally spaced around the nut.
Unfortunately, it's chock full of proprietary customer data, so I can't share the parts or the assembly. But I can pretty well explain what needs to happen, and I've attached a JPG that shows a bit of what I'm doing.
I need to design a bracket to hold an RPM sensor at a certain gap to a spiral bevel gear. I've got a huge assembly model (non-Inventor) from the customer, as well as the model for the sensor. My plan is to start a master IAM, insert the customer assembly, insert the sensor and constrain him, and draw the various hardware I need around the sensor.
So I start by making a work plane that matches the bevel angle and is in a location so the end of my sensor will be flush to that plane. Create a sketch on that plane, then project 2 relevant axes to create the appropriate "origin" from which my location will be based. Place a point on one line, at a certain radial distance and constrain my point.
So now I've got a point and a plane that are where I want my sensing face and my centerline axis to be. What now? I was thinking that I'd create a work axis "normal to plane through a point", but this workflow isn't available in the assembly environment. I can't constrain a solid to a sketch point, so I really don't know what to do at this point in order to put the part where I need it.
Actually, I have more than 6 years experience on Catia V5 customization and vb and vb.net catia API's. What I am trying to do know is converting some applications or programs running on catia to the inventor.
The first program deal with the inventor API relating to the SweepFeatures class. So my first problem is about to find the right way to use the sketch3D for the creation of the path which is the input of the sweep method.
(oInvPartFeats.SweepFeatures.AddUsingPath(oInvProfile, oInvProfPath3D, kNewBodyOperation).
I know That is possible to create a path by using the CreatePath method when the input is SketchLines or any guide curve in the 2D Plan. Also, I tried to generate path by using the ProfilePath3D method of the sketch3D class but No way, the AddUsingPath method of the SweepFeatures Class doesn't accept it as path Input.
So I cannot imagine that is limitation of inventor because it was possible to do it by using the seep function of the model tab in the ipart document. How to create the path object as an input of the AddUsingPath method of the SweepFeatures class.
One of the computers at my office keeps randomly freezing, i.e. Windows freezes, not just Inventor, when working on a simple frame generator assembly. The freezing seems to be completely random, it can happen 2 minutes after opening the assembly or it can happen after 2 hours.
This only happens on this one computer with this one assembly.
The computer in question is a new Dell Precision M4600 (like a week old) running Autodesk Factory Design Suite Premium 64 bit (including Autodesk Inventor standard edition). Installing Service Pack 1 had no effect on the problem.
I'm having trouble with constaints, I'd like to constrain my sketch to a point in another sketch on a different plane. Is this posible in Inventor? If so how? If Inventor works differently how would you get a points in one sketch to be linked to points another?

View 2 Replies View RelatedFor our office I'm trying to figure out (so far without success) how it might be possible to constrain movement of a block's geometry to a single plane?
I can use a stretch grip but that will mean you can go in one direction only (positive) not negative, I want the freedom to be able to move backwards and forwards in the X-Plane.
Block I'm working on (progress so far) attached. It is designed to display height relative to a datum point in the block, and for use in drawings so you can place it all over and pick up levels to top of things like steels.
The block allows the use to pick the stretch grip to go up, so the objects moved will be to a point which will be relative to the base point of the block, which will be set at a datum level for the drawing. Relative to the base point a field will extract the y-coordinate of an object in the block, add a suffix of mm, that will then be the level relative to the base point.
I want the move command constrained to move the block geometry in the drawing but only in the x-plane; if the entire block moves accidentally in the y-plane it will also move the base point also, which destroys the idea of measuring against a fixed datum.
I want to sample part of an image and clone it at the same point on the horizontal axis but further along. Holding down shift doesn't seem to work for constraining any of the brushes along an axis. Is there a way to do this?
