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.
View 9 RepliesUnfortunately, 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.
I 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.
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.
I created a work point on a part. How do I delete it? Right clicking on the work point in the model browser doesn't give a Delete menu item.

I am trying to link component parameters to the assembly and leader text always picks up the particular part in the assembly rather that the assembly as a whole. I want to point to a door assy with leader text and say it is "DOOR A" using model parameters but leader text picks up the particular part I am pointing to with my leader text rather then the assembly.

We have a custom-made sheet metal punch consisting of a 5x5 matrix of 1/8" holes. We export flat patterns from Inventor as DXFs.
We normally make DXFs by creating a view of the flat pattern on a blank IDW template (no border, no title block, nothing) and export that view as a DXF. This lets us orient the view at will, unlike right-clicking on the flat pattern in the browser and selecting Save Copy As.
When the sheet metal guy assigns tooling in his software, he needs to get each punch to "lock onto" the corresponding feature in the DXF. Normally this isn't a problem, but it has been with this gang punch. The center hole of the punch needs to lock onto the correct hole in the DXF, and it can't always seem to do it. I've sat alongside the guy as he does this, and in his software the centers of the circles show up as dots/points. But on this punch, there isn't necessarily a dot in the center of every circle, and it's possible that the center hole, which really needs the dot, won't have one.
I've come up with a workaround for this: a work point in the IPT. In the attached part, it's feature Tooling1. The sheet metal guy confirms that if I include the work point in the DXF as a point (in the AutoCAD sense), he can lock onto it. However, I find that if I generate a DXF from the flat-pattern IDW, the point is lost. If I generate an ACAD DWG from the IDW and save the DWG as a DXF, the point comes through in the DXF. But that's an extra step.
Is there a way to export directly from IDW to DXF and not lose the work point? Or is this as good as it gets?
For the sake of simplicity, the attached part has no bends. I realize that if I did, I'd have to re-create the points in the flat pattern, but that's another discussion.

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 have a piece of steel that I need to flex. It is a piece of blue tempered spring steel pressed against the corner of a brass pressure transfer. 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.

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.

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 have "Shared" the sketch.

Why 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.

View 2 Replies View RelatedI 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.

I need to find a way how to insert a point or a * on the center point of a hole and put it on a different layer. The reason for this is - I am a CAD tech for a welding shop and we cut parts out of steel and we use the dxf file format for our plasma table to cut parts. For example : if i have a 1 inch thick plate and want to put a 3/4'' hole in the plate the hole will be distorted because the hole is smaller than the material thickness. For these situation we can use the plasma table to burn a point or a dot on the center point of the hole. But to do this the point or dot must be on a different layer in the dxf.

View 2 Replies View Related I set up our company log which gets embossed on most parts as a sketch block in an .ipt. The .ipt contains nothing but the sketch block. To use it, the designer only needs to derive the Logo.ipt file into their part and then use the scale setting to set the derived block to the desired size for that part. The result is a scalable set of line geometry that can easily be used for extrusion or emboss that is standard for all users. It works beautifully, that is until you try to use it in a sheet metal part in 2012.
For some reason, when this same part, which works perfectly in normal parts, is derived into a sheet metal part an error pops up stating that, "Selected part does not have any geometry that can be derived." Say what?
I was able to find a workaround by directly copying the block into the sheet metal part, but you no longer have the ability to go back and scale it if needed. Even more strange, when the block was copied over, it could not be deleted from the new part.
Is this just a bug with 2012? Why does it work in a normal part but not sheet metal?
