I'm currently working on a model where I'm subjecting a vertical wire (5 micron radius, 20 micron height) to a transverse load. I made an assembly of a 18 micron length section and a 2 micron length section, so that I can apply my force to the 2 micron tip, while leaving the bottom face of the wire fixed. I am trying to find the minimal force needed to fracture the wire (i.e., altering the force until the max stress hits the material's ultimate tensile strength). However, I've realized that decreasing the mesh size drastically changes my results, Obviously, decreasing mesh size should increase the accuracy of the results. Instead, by decreasing the mesh size, I actually am diverging from my results.
i've managed to layer a scanned drawing (and edit it and all) over the given template... but when i drag it over, it's HUGE. so of course, i haev to decrease the size so it fits on the t shirt template... and when i decrease the size, it gets grainy and pixilated... and i can't have that happen! especially on a t shirt design... it's supposed to be a a solid, single line...
I made a huge mistake when I began my latest design project. I made it too large. Now, I need some help to decrease the size. Even if the quality of the image will get alot worse. The file is huge so I can't use the "Save for web.." option. So, pleae help me. How do I decrease the the image quality and thus the file size?
the shortcut in the mac version (CS6) for in-/decreasing the font size is apparently "Cmd + Shift + >".shortcut for windows versions? I can't find anything in the shortcut overview.
I find myself in the unfortunate position of having to resize a lot of text by one point size. So I wanted to find the key command for decreasing the text size by 1 point. I found several things online that worked... except they decrease it by TWO points. Not one. They are:
Command Shift <
and
Command Shift .
Both work... except they decrease the font by 2 point sizes. How can I make it go down only ONE point size?
PS I'm using CS4. And I can't select all the text because I need some of it to stay as is... while reducing the size of other text. Oh, and I'm on an iMac.
Where do I set the keyboard shortcut for increasing/decreasing text size in Photoshop CS5? I know it is supposed to be Keyboard shortcuts, but I don't find it in there.
I have an assembly that has somewhere a hole with a round bar that exactly fits in this hole. But when meshing the assembly, the mesh of the hole and the mesh of the bar are different.
The result is that the different parts do only seem to touch each other at the edges of the mesh, resulting in high stresses.
See picture.
I tried to made a derived part from the assembly, but that one does not finish meshing. After 48 hours, the progress bar is still half way. While the one above did finish in about 15 minutes. What can I do to make the meshes match?
First off, my experience level is basically an advanced beginner, so speak to me as if I am a 10 year old.
Now, the attached link to a Word document illustrates my issue: [URL]....
I am getting horrendous colour shifts when saving to a jpg in photoshop. It looks OK in photoshop when I open it, but when viewed anywhere else it is brutal. I included screenshots of my colour settings and I am working to sRGB and embedding that profile when I save, so I am at a loss as to why it shifted so much.
I'm having a bit of trouble re-sizing a mesh in 'sub-object' mode, so I must be completely off base and not understand what 'sub-object mode' is at all.
My steps below re-size it, but ... also splits the Body object into (Body, arms, legs) and spread them apart.I was hoping to be able to re-size my Head and Body meshes, and have them smaller, but still together? To re-size, I
1. clicked on the 'edititable poly' modifier for my skinned Body mesh (after unchecking 'always deform' in skin)
2. clicked on the icon for poly selection.
3. ctrl-a to select all
4. right click and choose 'scale'.
5. in global put scaling of 50%
and the result was my broken apart mesh in the graphic.What's the correct way to re-scale a mesh in 'sub-object mode'?
We are trying to use 3d scanned data in Inventor to facilitate our design process. We don't need perfect and good looking 3d scanned models ready to produce, but we need some accurate measurements from holes and faces that we can use to design our own products.
So mine problem is: How I can get those scanned meshes to Inventor that I can get some dimensions from it, project some geometry to my sketches, add some constraints between scanned surface and mine designs, etc...?
I have tried some Add-Ins like Sycode's STLImport and Sycode's software called Mesh To Solid to get those mesh files open and I can open those "converted" files in Inventor, but those are only some kind of surfaces called Composite or Surface which consist of tiny triangles.
I am using Inventor 2013, with the stl importer plugin also installed. I have had a objected scanned and the scan is been given to me in STL file.
As you may know that once something is scanned, it becomes a mesh object with many triangle faces. This is more evident on curved parts of the object.
Is there any way to smooth the surface so the curves do no look like very small step trying to form a curve? If the surface does not become smoothed out so its seen as one surface then I will have to adjust every small face at a time?
I am trying to make a shell of a mesh feature after I have upscaled it.
I do not think the regular shell technique will work as my mesh feature has hundreds of surfaces. So, I decided to open the file with my part in it and then derive the same part but a little bigger using the derive button. I would then subtract out the smaller, original, one to make a shell of the bigger, derived one.
Unfortunately, when I use this method to upscale, the 2 objects are not concentric so I cannot make the uniform shell that I want to.
I have attached the file of my mesh feature in case you want to see it. not that you will have to convert the object you see on my file into a base feature before doing anything with it. I did not because it would have made the file to big to attach.
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 am working with 2 mesh's they are the same shape but different sizes. I want to subtract one out of the other but only after they are both "concentric". The objects are not symmetric so I cannot officially use the term concentric but I do not know any other term.
My problem is that I cannot get them concentric.
Things I tried:
They will definitely both have the same center of mass so I tried doing things with that but to no avail.
I also tried to set 3 constraints (distance between identical surfaces on each mesh) equal to some value x but it did not let me. If it did, I believe the smaller object would have no place to go but right in the center of the bigger one.
I have attached an assembly with both of the objects.
But during the first analysis, it stopped and gave me a message saying: Improper constraints, material or mesh..Then I went on the internet for finding a solution, I came up with 1 solution - to set Average Element Size to 0.040 instead of 0.100.
After I tried this it came up with yet another "error": Mesh failed: Very large number of elements generated, mesher cannot proceed further!
As my journey through Inventor 2012 continues, I have the task of creating Expanded Metal Mesh.I have the basic sketch of the shape and all is well. My question is how to pattern the sketch of the shape so that I dont have to copy or mirror over 100 of these sketches/outlines to form the pattern? Essentially I want my mesh to fill in a 30' x 30' square.
Working on a simple cylinder with a coil runing around the outside of it. For some reason the mesh does not handel the geometry correctlly - can figure our why - any thoguths ? Attaced are pics from the meshing and the model.
WHAT I A TRYING TO DO: is bend a grid/mesh pattern of material to a certain radii and distance. In the attached DWG I have used either Extruded or Sweep to create the existing (latitudal?) grid but am not doing well creating the perpindicular grid at the arc drawn below the existing (lat.) grid.
I believe the dwg is a good representation of what I am attempting to do, and I am trying getting to my end result, whether it means using what i've begun or starting over, and using the "Best Practices" to achieve such.
I've modelled part of a ship's deck, it consists of rather simple geometrich shapes(Plates, knee brackets and profiles).
However, when i model the assembly and do some negative extrusions in order to get the model how i want it, it leads to a face failure during mesh generation.
I have some DWG files which contain walls of old castle some of the vertex are missing so I have to join them manually or found software to generate them automatically Does solid works have this functionality ?
After joining vertex how can I convert walls to meshes?
I downloaded the .stl file from here, which is a very detailed model of 20mb size:
[URL].....
it can be opened in inventor and is shown as a mesh object. Then I tried the plugin "Autodesk Mesh Enabler" to turn it into a solid. After almost an hour it produced something of 350mb, but it cannot be opened anymore, it crashes inventor immediately. Are there any settings to that plugin to reduce the number of elements that it creates?
I heard Mesh4CAD is a similar tool for autocad. I am installing autocad now, hoping that it is more powerful for these kind of things...
I just need to take measurements and attach new objects to the model, or can this somehow be enabled for mesh objects as well, without converting?
I often use the FEA tool of Inventor, I already had some "known issues" like degenerated element.
I have to test if a tank (full of oil) can resist at a 10G shock in every axes (six simulations separated). For simulated the oil, I created a part from the tank assembly using boolean tools (combine, and so on...). Then I applied the stresses on the oil part, in the interaction surfaces between oil and the tank.
When I mesh, there is no problem, I can save, quit and load the assembly, the mesh is OK. Once I have set all the parameters, whatever the simulation settings, I can see the message: "Adaptative refinement" then it stops after the first iteration, and the mesh disappears.When I repeat it, sometimes the simulation is blocked at the "adaptative refinement" step. I cancel it and a "mesh error" appear...
is there any way to make gradyally decreasing in size circles in photoshop. like on car windshields in edges if you noticed, starts from black and then it sort of fades away with pattern.
Falftone effect creates crappy jagged circles. I am attaching approximately what Im talking about, manually made every layer for it...
I'm trying to emulate this cool sort-of-film-like look that's been so popular lately on various places around the web, namely with decreased dynamical range. In Photoshop you can do it just by adjusting the output levels. How to do the same in Lightroom? The only thing I could think of was pushing the Fill Light slider to extremes, but it doesn't o the job. I'm on Lr3.
