AutoCad 3D :: 3D Simulation On Deformation Of Plastic / Elastic Materials
Jun 6, 2012
I am looking forward to a CAD application that can simulate or show the end result of applying pressure to a plastic material. I have CAD drawings of EPDM Joints, Aluminum Sections and I want to simulate the action of glazing over the EPDM Joints, how the joints form is going to be transformed when the glazing is inserted in-between them i.e. a Window Sash.
I have an assembly with a FEA simulation result. I can run a report and get the reaction forces and moments at each constraint. I would like to run a new simulation with different constraints and use the reaction results from the first simulation as loads in the second one.
Currently I do this by running a report on the 1st simulation to get a table of the reaction results. I then manually add those forces to the 2nd simulation. This takes time to type and the forces must be edited each time I re-run the 1st simulation.
Is there a way to use parameters to automate this?
I have a 2D pipeline layout. Nodes on the pipe are known by their X and Z coordinates. A FORTRAN written code calculated the nodes displacement in 2 direction of x and z.
I have to draw the nodes, connect them to each other to obtain pipeline layout and then draw the x and z deformations separately to show the deformed shape.
Input format is like PN x y z 1 0 0 0 2 0 0 10 10 0 0 100 20 10 0 100 40 40 0 100
I though ACAD might be an easy tool to do this. I am trying to use MacLee's or Geobuilder's LISP routine to import the x and z coordinates into CAD.
MAcLee's routine doesn't recognize node numbers at the beginning. So I shifted into Geobuilder's rotine. Still I am trying to use but with no lock till now.
Any easier method for drawing these simple stuff, coordinates and deformation? Is it possible easily in ACAD? My other limitation is that ACAD is the only software I have in my hands.
Deformation occurring when printing with different scales,
It is gorgeous that one can preserve the text size, hatch size, dimension size, etc. regardless the scale the drawing is going to be printed with.
For example, if the text size, hatch size, dimension size, etc. are proper as the drawing is printed with a scale of 1:100 then how about printing this drawing with a scale of 1/50 and 1/200?
A scale of 1:50 looks fine (attached) A scale of 1:200 has some overlaps! (attached)
Then how to get a nice drawing (dimension size, text size, hatch size) when printing the drawing with a scale of 1/200? In other words, how the annotation objects can be adjusted proportionally such that no overlaps and distortion is occurred?
Basically I'm trying to fake text in a book. I've attached a few images which basically outline my problem. At the moment I'm using a text path to deform my text, but it doesn't do the perspectival deformation on the text that I need. The "text deform" tool is too simplistic, it won't match up with the contour of the page properly. Something which sits mid-way between the two would be ideal, but failing that,
I was wondering whether in PS exists the following functionality:
you apply a 2d cage to your selection and then move the cage's control points to deform your selection. much like a FFD modifier in 3ds max, the only difference being that it is applied to a 2d image instead of a 3d mesh.
I'm trying to simulate metal deformation. To achieve a realistic metal denting I'm trying to use Cloth. The problem is though, whatever settings I try, my cloth-box collapses from itself. My question is; how can I set cloth up so that it can be as strong as metal, and only deform when I drop an object on it (that's where the denting comes in)?
How do I create this plastic molded part? I need to create a rectangular frame with L shape cross section and then add center round hub and then add ribs.
What I want to start doing is small plastic or acrylic tools and I wanted to know what is the best solution for this purpose and were I can get some pdf or video training for it.
I am trying to model a plastic part which is attached to each other on one side of the edge and it snaps into each other on the other side. I was able to manage the hald section of this part but not sure how to do other half.
Suppose we have a plastic part modeled as bent around a cylinder with an x-axis. Because the material is plastic and the manufacturing method is injection molding, part stretch is not a concern.
Suppose further that the part is a solid part that will be converted to a straight spring. The part needs to be flattened to obtain the correct spring dimensions--the part may have variable width in the x direction.
I am building a consumer electronics prototype that has mechanical and electronic components. I have built the assembly I need at the dimensions and measurements required. I am having trouble finding tutorials or instructions on how to derive a shell or frame from the complex inner components of an assembly. What is the general approach I should take, I'll get to the details. So far I've tried a loft that goes through the areas that have very specific measurements.
I found a pretty nice modification of font but I simply can't make it. There is a guide how to do it but it is not written very good, it looks some small steps are missinga and a greeny like me just can't make it.
Was wondering how to create this effect. I was also trying to think of an example of an item that was popular that uses Black Plastic Glass, so you could have an idea of what it looks like.
I have a few question about the autodesk material library. i'm using a plastic material and i'd like to add a transparency map. The problem is, the transparency option doesn't showup. And if i set the material to plastic (transparent) it doesn't showup too. what do i need to do?
Another question is, where can i find the arch&design library?
I need to remove the background from this image while keeping the straw and plastic wrap. Have looked all over for a tutorial, but no luck. how to do this
I need to cut out letters from plastic on a laser cutter. I use "no fill" and a hairline outline and it works fine. But occasionally I want to change a font to be "thicker" or have a thicker line but still maintain the hairline outline for cutting. I can get thicker lines on screen by using the contour tool but how to remove the fill and keep the hairline outline. To complicate matters, I need these letters to be joined together, so I also need to use the weld tool.
I've been shooting a lot of "alternative" stuff, much of which has included PVC and latex. Lighting it is tricky enough, but much of the items are wrinkled, and aren't amenable to being ironed--something about melting and causing a mess...
getting the smooth highlights back instead of the textures and wrinkles? I've used the smudge tool, which works OK---if the image is websized, but falls apart at print sizes. Cloning is always an option, but it's going to be a long and painful process.
I've seen this type of effect used on photos, mostly for fashion ads, and how its done. Possibly, it has to do with lighting during the photo shoot itself. But it seems to me that there is also a significant deal of processing in Photoshop.
Mostly what interests me is that quality that retains a photographic look, while at the same time gives the image a somewhat plastic and unrealistic feel to it.
I tried to attach a sample image which shows exactly what I'm talking about... but it seems that since I'm new here I can't include links until I have at least 5 posts under my belt. You can see the image if you look here: [URL] ....
I am using CorelDRAW 12. I . would like to print the image on a transparent plastic with 2 colors separations. I scanned the image with black and white color. I would like to print 2 colors on the Transparent Plastic: (1) Black and (2) White
so that I can see White color on the Transparent Plastic under Black Color and then I can't see s.th through the Plastic Bag because the Transparent Plastic is printed with White color and Black color and if I print the image on Red Plastic, I will see White color and Black color on Red Plastic, but I don't know how to solve it in the fast and right way.
I've created a successful FEA simulation in Inventor 2014 and obtained results. But I want to see the highest stress in a defined area that is smaller than the entire part (I have some stress concentrations that are throwing off my 'max'). Is there a way to probe an area instead of just a point? I'm tired of creating a dozen probes to find the 'local max'.
I'm developing a program which runs several simulations and obtains the results automatically.
I'm using the dynamic simulation API created in Inventor 2013. For that I use the GetResultValues(ByRef values() as Double) method of the class DSResult.
I used the method inside the VBA of inventor and worked well. But when I wrote the program in Visual Basic Express 2010, the method doesn't return anything.
I share an excerpt of the
Dim odoc As AssemblyDocument odoc=invApp.Documents.Open(testPath, True) Dim dsman As Inventor.SimulationManager = odoc.ComponentDefinition.SimulationManager Dim dssim As Inventor.DynamicSimulation = dsman.DynamicSimulations.Item(1) Dim oJoints As Inventor.DSJoints = dssim.DSJoints oJoint = oJoints.Item(1)
[code]....
The method GetResultValues(values) should modify 'values' to a time,value vector.
It works well inside Inventor, but doesn't in the program in VB, although it runs the simulations and does everything else right.
