'developing' or 'unrolling' or 'finding the true shape' of a 3D surface? Something similar to Robert McNeel's Rhino3D's UnrollSrf command to flatten a surface. (Is a mesh better?)
I am drawing the frames for a wooden surfboard which has curved spars (the surface in question) which need rolling out flat to make a template. The surface is curved in the XY axis only, so in theory it should be developable.
I've got a fairly complicated polygon mesh that I turned into a mesh. No problem. Then I try to convert to a surface and while the geometry is accurate the isolines change dramatically. I'm trying to bring the item into Inventor so that I can have a clean surface to work from. Unfortunately I get what you see in the picture. The top left is before converting to a surface. Bottom right is after.

View 3 Replies View RelatedBelow is my test procedure for "Create Curve Mesh Element" by Inventor simulation 2012.
1. I made a box 100(W)X100(D)X20(H) with 2xR20 (mm) fillets at the opposite edges.
2. I copied a box I made for making 2 type mesh.
3. I made mesh on the box without "Create Curved Mesh Elements" option.
Node number: 2374
Element number: 1365
4. I made mesh another model with "Create Curved Mesh Elements" option.
Node number: 2374 (same number, not increase)
Element number: 1365
Mesh shape is different(please refere attachiment jpeg file).
I think that "Create Curved Mesh Element option" is not for making second tetrahedron elements.But I cnanot the true porpose of "Create Curved Mesh Elements" option.For only P method, not H method?

I have received some sedimentary data of a seabed. I also have other geological layers the sit beneath (all in XYZ format). I have created point clouds using this data and would like to create a surface in order to use the elevational banding to represent thickness. Here lies the problem.
When creating a surface from the point cloud (whole extent), C3D seems to fill in gaps in the data. Is there a way that C3D can create a true representation without all the lines joining parts up? I know that I can edit the surface by deleting lines but this is very time consuming and I'm wondering if there is an easier way to do this. This problem isn't exclusive to point clouds either, as it does the same when adding points to a new surface.
I have attached a couple of screenshots. The first shows a Point Cloud with colours showing the desired effect. Unfortunately C3D doesn't allow me to print this. The second image shows how the surface looks when created.
In most cases threaded parts are designed without true surface (just cylinder with texture) thus part surface area is calculated wrong (less than it is i real world)).
any automatic way to get true value of threaded surface which is modeled in traditional (simplified) way?

View 3 Replies View RelatedHow can I print in black and white while using true colors? I've tried the monochrome ctb, monochrome stb, looking for solutions in these forums, etc. The std 255 colors are not a problem. It is only when I use a true color. When I tried the monochrome stb setting, the fill color on my multileaders did not change.
Also, in paperspace, with viewports that had solid objects in them, I used to be able to print and have hidden lines removed without them showing up that way in the viewport. (used 2008 at the time and have jumped from that to 2012)
I seem to remember that the was a variable command that controlled this but I can't remember it.
How to drape OS Mastermap/DWG over Profile DTM Surface Mesh? I've been trying for hours and can't get it to work. I've looked at articles online and they are hardly any use as they show you how to do it properly.
View 1 Replies View RelatedI'd like to be able to create a surface or mesh from contour lines to give a better 3D representation of terrain than just contour lines. "Drape" seems to be the tool ACA, but I'm wondering if AutoCAD can do something similar. LOFT sorta works, but even then, I have to do it in sections, and I'm not really looking for a solid.
View 7 Replies View RelatedWhen I plot to paper from TV2012, I'm good with monochrome - black lines, white background - awesome.
I would *like*, however, to plot a few things to PDF, but retain the view I have on my display - I.E., lines/labels of various colors and a BLACK background. I've been poking around for a bit, and if there's a way to make that setting, I'm no finding it. Everything I try has gotten me colored lines/labels on a white background.
I have created a TIN (triangulated irregular network) of an existing survey in my terrain modelling software (12d Model). I am able to export (save-as) the TIN as 3D Face Triangles for opening in AutoCAD (2012) or similar.
My ultimate goal is to create a solid surface in Inventor. The surface has to be seemless (stitched) in order for me to create a new sketch and extrude to this surface. Finally giving me a part in Inventor that represents my ground. I would then want to use the same process to bring into Inventor all other Civil Design works created in 12d Model such as roads, earthworks platforms (including dams) etc.
I've tried stitching (Inventor and Microstation) without success. Inventor keeps crashing and Microstation looses data. AutoCAD (2012) won't let me create a polyface mesh from 3D Faces. I tried doing a mesh, surface union without success. Programs either crash or data is lost.
I have an autocad drawing that has a building floor plan.
I need to "rotate the building 90 degrees" or "rotate the USC 90 degrees" in order to line the building up to TRUE project north (architect has a Revit model oriented to true north that I need to match when we combine our files in Navisworks)
I have tried DVIEW > Twist.. which I thought was it, it rotated my drawing, but the USC rotated with it. I tried the USCFOLLOW with no luck.
Also tried going into UNITS > DIRECTION and tried VP with no luck.
I understand that I can just select the entire floor plan and manually rotate it BUT, the building is not easy "shape" to work with, so it is next to impossible finding the "center" of my drawing to rotate it (I need this to be brough into Navisworks WITHOUT rotating the file again)
You would think this would be very simple to do and take 30 seconds. I have googled everything with no luck. I just need to change my True north
- doing this in modelspace
- needs to be align with a Revit model already oreinted to true north
- just need to rotate the drawing OR UCS 90 degrees, but can't find the "center" of the drawing
Ok received parts from a customer. It was ALL mesh features.I converted some of them(the mesh features) to Solids. Some would not convert to solids (converted to surfaces).
I need to have the COG show up correctly. Yes, I have a physical COG. I know where it is supposed to be.
I am trying to use this and several other parts (with mixed, Solids, Surfaces, Mesh features), in an assembly AND balance it all thru a common lift point.
How can I correct the COG of the individual parts, so that the assembly is correct.
I have work planes for the corrected COGs, but I am afraid that I will need to calculate the new COG for the assebmly.
I have a dwg file of a section of a tunnel that has been exported from Microstation as a polyface mesh surface. What I am trying to achieve is cutting a hole into the surface. I am assuming that I cannot cut a surface directly, but need to convert it to a solid first.
I've searched this site and I have tried everything I can think of to no avail. Inventor does not seem to be able to convert the surface to a solid. Also, when I import the surface to Inventor, some of the triangular meshes are not there, and there are too many "holes" to patch them manually. I've also tried using lisps in AutoCAD, but on the surface and 3D faces after exploding it, but for example m2s.lsp or f2s.lsp do not seem to work.
I have also had the same file exported from Microstation as ACIS .sat, but version 18.0 is not readable by Inventor. Is there a way to convert the ASCII file to an older version?

View 3 Replies View RelatedI am stumbling through the lessons and am stuck on Lesson #1.For those who do not know, it is to model a helmet similar to a dirt bike helmet. I have created a smoothed poly, removed much of it to create the top portion of the helmet (or cap).
I have created a poly shape using the Mesh >> Create Poly command. I have extruded said poly 3 times to shape the front facial guard.
The next step tells me to use the bridge border edges command. My problem is only my "cap" is showing a border edge. The facial shield poly has no border and I cant figure out why?
I have tried Display >> Polygons >> Border Edges and it doesn't make a difference on the facial shield.how do i view the border edges on said poly?
I'm physiotherapist and researcher interested in human body posture analysis. Goal of my researches are to make 3d digital model of human posture. Right now I'm using Microsoft kinect to build a human body model, but it's difficult to do automatic analysis on that mesh. In our team we create an algorithm which analysis posture, right now we base on points located on the body, for that is necessary to manually locate that point's which is inaccurate and time consuming. Our idea is to use divide human body into segments and then fit in those segments some geometry figures ( cylinders , bal, ), next step is to calculate center of masses of those figures, so we simplify the posture to 20-40 points , and calculation of those points can be made automatic.

I created a 3D math surface using 3DPLOT. However my outcome is a polyface mesh and I need to convert it to a solid. I have already tried the "Convert to Solid" & "Convert to Surface" options in the Mesh tab but I get "Mesh not converted because it is not closed or it self-intersects." I also tried the f2s.lsp but I am unsure on how to select my object.
