Haven't used AC in a while and hoping this is a simple question, trying to take a polyline (in this case a coil shape) and add a diameter to the line. This 3D object will then be imported to COMSOL for some thermal expansion modeling.
I am trying to loft a triangle around the path of a helix. I want the top point of the triangle to be facing in such that the ouside surface is flat (in the veritcal direction) for the entire helix and I have the two triangle cross sections oriented to do as much. Whenever I try loft it, autocad associates sides of the triangle that aren't supposed to connect causing the triangle to twist along the path. Is there a way that I can easily tell autocad which sides I want to connect?
I have a helix I've made, and I want to turn it into a thread in a hole I've already made.
I'd also like to make a matching bolt to fit the said thread. Keep in mind my thread speficics are not importan this is all merely for a proof of concept.
I do know know if auto cad offer a say to make a bolt and so on w/o too much work -but I've attached the said file and the helix I'm concerned with is in the "threads" layer.
Trick to keeping objects aligned with a helix when using an associative path array? The animation below demonstrates the problem where I can't seem to keep the "treads" on a spiral stairs aligned with the center of the helix. (fewer objects accentuate the problem)
Everything draws correctly in shaded mode but it you are in wireframe mode with the object selected at the object level the grid and the selected object no longer draw.
I am working on a project that involves a screw conveyer(auger) with a 3" od, 1.5"/flight and a 0.800" ctr shaft. I modeled it without any difficulty using the "helix" function in a 3-d sketch & then swept a rectal around that path. The problem is, I need paper templates to layout the pattern on the steel. In the past I have made use of the "flat pattern" feature to print paper templates for tube notching and such, but that function prompts me with an error message "no surface to flatten" Attached is the full screw(augShaft9in.ipt), a single flight and 2/3 of a flight(i dont think a full flight will flatten & not overlap). Need to getting these patterns printed.
what ive been trying to do is make a helix that sweeps around a rectangular prism i was able to make it in solid works but i cant find a way to do it in inventor.
When you sweep a profile along a helical path, use the plane normal sweep (instead of perpendicular sweep) to orient profiles suitable for coil or spring. In the example below, the sweep path is a constant radius, variable pitch helix.
I am working on Sweeping three helix profiles around a cylinder to create a screw thread. When I sweep the profile, Inventor gives me the error messages:
"The attempted operation would create a self-intersecting surfaces. Try with different inputs".
or
"The attempted operation did not produce meaningful intersection edges from the face-face intersection. Try with different inputs".
However, this is exactly what I need to create the helix profile I require and eventually increase the size of the Extrusion Sweep profile to 80mm. When I increase the sweep profile to 80mm I get the same error message about the self intersecting surfaces.
I am working with Autodesk Inventor Professional 2011, 64bit, 8gb RAM, Windows 7, Intel Core i7-2860QM.
I have generated a gear set using inventor. Now I would like to 3d print the gears. I have uesd the export tooth shape to get the true tooth profile. now I am attempting to use the coil feature to generate the helical tooth. The problem im running into is in the coil tool I can only give it a Revolution and height dimension. The hight is the width of the gear, but I am having a problem converting the helix angle to the "Revolution" perameter. I have read other posts and they say that it is Helix angle / 360. I have tried that and then compared it to the original gear generated by inventor and it is not even close. I need to do this on in internal gear and match it to an external gear.
Is there a way to draw a helix in X3? It is not evident to me and a search does not turn it up. Alternatively, I could draw a helix in MatLab (or such) and import it, but what file format would make it manipulable in X3?
I have a helix spline that is pretty large. The larger I make it the more evident it is that it is made of segments. I can't find any place to adjust the interpolation. Is there any way to add more segments to smooth it out a bit?
I've got a Mesh which consists of several Helixes with regular Tubes in between. They are all welded together, so it is one long Mix of Helix and tubes. In Animation, the amount of Turns in each Helix needs to be changed (from 0 Turns, up to 50 e.g.).
First I attached bones to each helix, but strechting the bones only leads to stretch the Helix - not reducing the Turns. In another attempt, I took a regular Tube with a Path-Deform-Modifier and a helix-spline, so I had good control of the Mesh, by changing the splines-parameters. But since my Mesh consists of several individual helixes, I cant use it cuz i can only select 1 spline in the deformation-modifier.
I use Cad for Mac 2011. I made this "3d"-wire drawing to find out the angles of an object. Now when I make an angular inquiry the value given is right. When I try to put in an angular dimension it does not work. I put in a screenshot here to be more clear. This is the situation viewed from southeast:
Agular dimension.jpg
So, the angle I want to put the dimension to is the one between the red lines. When I choose "Angular Dimension" and then pick the two lines the dimension is automatically put on the two white lines next to the red lines. While the verteces of the dimension lay on the picked red lines the arrows point to the white lines and the value given also refers to them.
is it possible to define a 'natural direction' at a pin, in which a wire should start when connected to that pin? This would seem to be natural for me.
As the attached picture shows, my wire is connected at this pin in a weird direction (because I need to route it through the indicated segment).
What is the best strategy to do it correctly?
Another question: I increased the diameter of the segment, hoping that it means that the wires are constrained within the segment, but are free to move withini this. But they all seem to be constrained to the centerline. What I want is that all my wires pass within this 'tube' of 30mm diameter.
I work for a company that does custom electrical enclosures and we use a 2010 version of inventor professional. What would be required to run wire in assemblies easily and also output wiring diagrams?
I would like to automatically wire up the event handlers for my .net assembly when it is loaded. For instance, does AutoCAD look for and call a "Loaded" or "Initialized" event when it loads my DLL?
I am having trouble constraining the wire track in the attached picture. I want the track to move naturally when the sliding piece moves, however it folds over on itself and doesn't stay in line. I can't figure out anyway to make it look uniform and move they way it should, is it possible in inventor?
How best to go about creating a "wire mesh". What i have tried is to create a solid flat (2mm thick) piece of material. I then draw a diamond shape on the surface & extrude it so as to give me a void.
Then i use the rectangular pattern option. The problem is that when i try putting in the amounts of the "holes" i need to brings up message to use optimized compute. I do that and then when i click to crate all the "holes" it comes up with a pattern failure error.
I made the parts but cannot make the wire fit in the assembly.Is it best yo make the wire in an assembly mode then as a individual part to fix in the assembly.How would you make the wire and also so it connects correctly in assembly
