  1. Dear Friends, I need your help with the following case. I have a XYZ table which is coordinates and elevation. When plotted in 3D in Matlab or Excel, it results in a 3D surface plot which shows the topography of an area. My end goal is this: (1) create a solid object with these coordinates, (2) overlay the object with an aerial photo and last (3) design some machinery/buildings on top of it. In short, I want to do the Autocad equivalent of the Geo-location operation in Sketchup (see attached image). If I understand correctly, I need to first create an STL file and import it in Au

  3. Here I have a flanged Alclad Plate I developed in AutoCAD2015 Trial, I since ran it through CorelCAD 2015 because I ran out of trial time. I have to sort it out to get more time. The problem is that I tried to put a third flange on the plate (a 90 deg one) after I had successfully extruded all the holes you can see. The 3rd flange was created by extruding concentric cylinders and subtracting a rectangular block from that. I found out I was having trouble when I tried to put a relief hole in the corner where the end of the 3rd flange meets the plate at a perpendicular in
  4. I am working off of this code cadpanacea.com/node/186, but when I try to run the following, the radius of the circular hatch varies based on the 'ctr' variable's distance from the origin. I would like it to depend solely on the 'ctr' and 'edge' points.

  6. Hello everyone! Here is my problem, i need to run a simulation model of a building in Fluent Ansys, the thing is i have a model in CAD of the building and i need it to be fully solid so i can convert it to .SAT and import it to the simulation program. I've browsed the forum and the web a bit and the solutions i found didn't work for me. I need a little help. Here's the link for downloading the file, hope it works with links from dropbox: https://www.dropbox.com/s/ncj6knkdslwagv8/Ptam.dxf?dl=0 I tried using the file manager but could only up the pic not the file, maybe is to big...
  7. Hi everyone, here's what I'm trying to do: I have a lot of curved bridge girders, and I am using MASSPROP to find the centroid location, and then manually typing in the centroid coordinates as the center point of a sphere. Awhile back, I found this code that is supposed to do precisely that, but these days it is adding a sphere at a corner point, not the centroid. Any help would be greatly appreciated!

  8. Evening All I work as a design assistant for a West End Set Designer who loves working in forced perspective & vanishing points. My question is how do I slice/trim a 3d polyline that runs through a solid. I basically want to cut the line once it touches the face of the solid. I would be also happy to add a node. Attached is a small example of the working file. Look forward to your responses Cheers James EXAMPLE.dwg
  9. Hello, I have a problem with artifacts in the 3D solid. AutoCAD didn't let me create perfect lofts because it has a restriction on every loft polyline having its vertices on the same plane. Thus I couldn't position them perfectly and they cut into the solid in places where I didn't want them to, creating extra edges and vertices. Since there was no way to fix that while lofting, I now have to try and fix it after the boolean operation. Here are the pics: Area to be welded: Overview. Above is close-up of one of the circled edges in screenshot below. So far I hear that I

    Mesh to solid

    (please bear with me, this is my first post and I am very new to Autodesk products) Hello I need help with a project I am attempting to do on Inventor. I used Google Sketchup to create a model and realized that it needed to be in inventor- I exported the sketchup as an .stl and imported it into inventor. However, it imported it as a mesh instead of solid. I can't figure out how to make it solid and I need it badly. (Yes, I know, I should have thought this through before using sketchup). Any help is appreciated, thank you I am using the student license for Inventor 2014
  11. Hi all, I am having urgent trouble with a project involving 3d modeling of terrain. This is a graduate-level project requiring ArcMap and Star-CCM+ software as well, which I am capable in, so I overlooked taking on the responsibility of modeling in Civil 3D (which I am a beginner at) and converting file formats. I was hoping one of you had some suggestions. I am attempting to turn an elevation model of the island of Jerba into a 3D CAD model for use in computational aeroacoustic modeling (any of the typical file formats - .igs, .stl, etc. work for importing the model). I brought the da
  12. Hey Community of AC, i've been working on my thesis, im creating pieces of 3d to hold a servomotor, and ill print it on a 3d printer, will be my first time and i dont want any mistakes since it cost some money, so while creating the piece i've been using a lot of Union-Extrude-Presspulls but using the P-P i've encountered with some lines that bothers me and makes no sense.. it seems like is 2 blocks united but it is not. ist just marks the line whenever i do the P-P, i have attach the picture so you can help me, what i want to know if i should ignore it, and it wont print 2 pieces instead of o
  13. Hello Lispers I do a lot of 3D modeling with AutoCAD and so far I been using solprof to convert my models from 3D to 2D drawings creating plans & elevations What solprof does is creating 2 separate layers and separates solid lines from the hidden lines (which is great) however, it loses the original layers that was used for each solid. My question; Is it possible to keep the original layers after a 3D is converted to a 2D drawin? We spend a lot of time assigning back the layers to the 2D shapes again. btw, we are using AutoCAD 2010 Any help is much appreciated

    solid walls

    hi all, my problem is that I ve a white line cross my building outside wall, which shouldt not exist. After Union it happened... How I can remove this line. I ve already tried to the command explode. It's not such a good solution. I want to keep my walls solid. cheers, jester
  15. hello everyone, i have a project that needs to get the volume of the certain of the hull of a boat. from 2D i use align command to get the 3D form of the hull. then i to get the shape/surface i use loft command. i am doing it right? but from the moment i tried to get the volume using massprop command it says, "no solid or region selected" see attached picture. and also as i tried to use the m2s.lsp it says "not a polygon mesh". I really do appreciate guys if you all can help me with this matter, i've been doing this for 1 days but still im going no were. also, the non-coplanar thing i always
  16. Al_H_C


    Hi All, Looking for some help with what is probably a fairly basic 3d Modelling operation. I have a series of planar surfaces arranged to create a relatively basic object. I am now trying to use the sculpt command to convert these into a 3d solid but keep getting the error message; "Modeling Operation Error: Operation did not add or remove material. Solid creation failed, no watertight volume detected." Is there any way of; A. forcing the sculpt command to work through altering some sort of fuzz distance option etc? or failing this B. identifying the non complian
  17. I have bee awat from AutoCad for a while. Using 2002. I inserted an an Angle block from PE Symbols into my Drawing, but it is only 2 dimensional. I have forgotten how to change the block to a solid, and then to extrude it to a given length. Any help would be appreciated. Tosagua
  18. Good Afternoon, I am currently working on a project that involves some basic collision simulation of an LNG ship in Solidworks. However, before I can do that I need to turn the ship (which at the moment exists as a series of curves, see attachment!) into a solid object, which I can then export as an IGES file. So far I have tried the PRESSPULL command on the advice of someone, and it hasnt worked at all, only produced a "not responding message". Can anyone help me apply a surface, or turn the curves into a solid object? Any help would be greatly appreciated by an extremely ine
  19. Gday All I have been taught a few years ago to draw in 3D, then solprof a copy of the file, cut and paste the hidden lines into the original files viewports. I find that this process can be problematic , in that when it comes to solprofing, many mistakes can be made. if there are any changes made to the 3d model, this isnt reflected /updated in the viewports as the solprof has already been done. my pc sometimes crashes at the solprof part of the process. Id like to know if there is a better way to get hidden lines on a 3d drawing. Have i been taught the wrong way to do things
  20. Like when I draw a cylinder, instead of a solid cylinder I get two circles joined by two lines. How do I change this so that I get the solid?
  21. Hello, I made an irregular solid object using the LOFT command and a few splines as sections. The object is approximately 200 units long and I need to get sections from it (polylines or regions) every unit. Is there any LISP that can do this? Thank you
  22. Hello there I am in need of help and some what of a beginner. I have drawn a large building model and exported a dxf. The dxf is a autocad_3dpolyline. I need this to be a solid object(s), I can use software AutoCAD 2009, 3ds max 2009 and FME. If there is anybody that could help, i would be very greatful. If there is any more infomation you need to know just let me know. Thanks in advance

    AREA Command

    I just got a quick question about the AREA command. So if I use the AREA command on a solid then the number it spits out is the surface area of this solid right? Let me know when you get the chance. Thanks
