  1. I am looking to add clarity to my models for my clients and one thing I think would help that would be to add colour to the models I have. Mainly I wanted the design to have some kind of bright colour and the existing topo to be a darker colour. Any insights into this would be greatly appreciated. Thanks, J
  2. Hi! I am trying to display all the elements from my subassemblies on the plan view. Can't find option responsible for display a bench from the subassembly called daylightbasin. I have a linework in a corridor showing bottom of the ditch, external side of a bench and link to surface, but all the options responsible for the bench seems to not working. Ideally I would like to add a feature line in all the places where my corridor change the shape, according to the created assembly, but really I have tried everything what I do know and it's just not working. I know I could do it manually, but I think that's not the purpose of using software like Civil 3D. As you can see in the last image, corridor line (external edge of a bench) is going in a bit different direction than the countours from the surface generated based on the corridor. Please help! It

    U-Turn modelling

    Does anyone has any idea how to model this kind of U-turn which is basically end of the road in the same time and it's curved at the end?
  4. Hi! I have a drawing with mixed points and blocks. Area is huge and I really can't work. I have an idea to replace all the blocks with points, hope it will reduce a bit size of the drawing. Could you help me with that? Uncle Google couldn't help me with it unfortunately... Simply - have to replace large ammount of blocks (two lines crossed with level in the central point) with points. Many thanks!
  5. Hi I have used the Extract Intersections between two surfaces to get a complex line but I dont know how to give a thickness to it How can I give a thickness to make it a solid? Thank you
  6. Hi Everyone:) I am working with contour lines. I don't have any trouble creating a surface from the contour lines (Toolspace > GIS topo > Definition > Contours > Add (with swapping edges selected) >> surface generates). What I was wondering is : IS there any way to create different layers for different slope gradients (as defined in the slope properties)? Ultimately what I want to do is be able to isolate the regions that fall into different slope categories and create boundaries around them. Any and all help is greatly appreciated!

    LandXML properties

    Hi, I created and exported a surface (as TIN model) in Trimble Business Center. I need to import this file to AutoCAD Civil or Bentley Inroads with certain properties. Is it possible to join information about colour or shading properties in xml code? I prepared the surface model with classification (road, water etc.) that each has different color. But when I import this xml file to Civil I get only tin as a surface in the same colour. How to import LandXML to Civil 3D or Inroads with this informations? Thanks in advance, Jacob
  8. I am coming up to the 3 year mark of working with Solidworks (in education not professionally!). I have an imported surface that I have made some modifications to for a hinge mechanism. It has come to my attention that I have made the surface 'too curved', I have spent hours trying to adjust the curves on the two sides - I only need the two sides curved around 25% less (doesn't need to be dimensionally perfect at all! just look right! If anyone could shed some light on how I would go about this... hopefully without re-doing the whole part again as I have several other pieces I need to attempt the procedure on also! See sample. If you would like to see the part, I can provide you with the upload link as it is too large to upload unfortunately

    Help with surface

    I need some assistance here... I have a surface that was created in Acad 09, Land Desktop (attached file) but there are no .xml files and the original drawing can't be located. The person who did the original drawing, no longer works here (of course). Anyway, long story longer, I would like to create a surface from the linework provided, in Civil 2015 format, but I've tried all I know and I'm coming up empty handed. Any help would be greatly appreciated! Thanks in advance. T BLOCK-Surface07.dwg
  10. i'm watching a video on youtube of a how to draw a helicopter blade, i understand what is going on in the video, but there is one point i can't follow. right when . I did exactly everything he did until that point, where i can't target the open loop(the line), instead it targets the sketch(3 lines connected to each other). I attached my last progress file blade5.SLDPRT .. i'm using solidworks 2015 sp2.1

    going nuts trying to find default

    Hello, I cannot find the default settings that control the point label style for a surface. I start a new drawing with no template, import an xml surface, turn on some contours and the points. I cannot find where that sneaky elevation style is hidden in order to change it. All help is greatly appreciated. Regards, phil
  12. I am working on a project that has dirtwork everyday that i need to run cut and fill quantities from daily asbuilts. Currently we are using Topcon Magnet Office DTM model (triangles), I am wondering if it will be more practical or accurate to use a Civil 3d surface to run these daily updates.
  13. I have two surfaces. An EG Surf and a Surveyed Surf. I need to splice the surveyed surf into the EG. The EG is much bigger than the Survey and etirely covers the survey surf. I want the two surfaces to tie in/splice together smoothly. So I thought I would add a 20' or 50' buffer around the survey surf between it and the EG where the two surfaces could gradually tie together instead of sharp changes to connect them. To do this I offset the survey surf border by 50' as a polyline and use that as a hide boundary for the EG surf. Then pasted both into a new blank surface. But instead of tying together in the new surface there is just a 50' gap/hole in between them. Any thoughts?
  14. Hello, I am using Matlab to create a surface I import into Autocad Mechanical 2015. Matlab uses a library to convert a matrix into a .dxf 3D surface. Depending on the option, the surface is either a cloud of points, or made of triangles or square patches (linking the points). (files attached) I can open these files with AutoCAD Mechanical and even export them in other formats (ie. stp), but I would like to convert the cloud of points or the triangles mesh into a surface (mostly to reduce the size of the file). For now I have 4 millions points (which gives me a 19MB .stp file when I export the triangle mesh .dxf file into .stp). I am planning to increase the resolution... So it is not possible to keep all the points and triangle meshs and I hope that there is a way to replace the meshs and points into a surface in order to make it easier to handle by AutoCAD, and lighter to export. (I need to export it in .stp (or similar format) so it can be used by an electromagnetic simulation software (HFSS, CST...)). How can I do with Autodesk product design suite ultimate 2015? (AutoCAD Mechanical, Inventor pro...) Best regards, Fabien triangles_and_points.zip

    surface labels

    Hello, I am hopeful that someone has found a way to utilize or extract the data in the surface properties --> statistics --> volume list for use in an expression for a volume label. I want to be able to create labels that let me dynamically show volume comparisons. Any and all help is appreciated. Thanks, Phil

    gettint the slopes of the streets

    Hello, I need to specify the slope of the streets of a city. I have the elevation points of streets. But, how can I get slopes in Civil 3D? I am working with Civil 3D, but I do not know the procedure for this work. I should create a surface from these points? The surface's triangles must be inside streets (the line of streets should be as breaklines)? Thank you in advance, Mohsen

    Creating Surface Profile

    Hey everyone. I am new to AutoCad due to the fact that I am helping out my father-in-law with his Civil Engineering business. I need help with surface profile view. I have created the alignment and created the profile (in model view) but when it generated the numbers were all on top of each other and its a giant mess. How do I fix this with out trying to individually move each number and try and find a spot for it.
  20. I have been searching for a very long time and i hope you can help me this way cause i found nothing. The thing is, i have a polyline and set its thickness but i need something like 3DFACE which can cover those open areas on the bottom and top. Nothing ever worked, except for dividing it into million pieces and applying 3dface/loft for each, lol
  21. Hi, I have a problem I can't seem to solve I have two pipes, installed eccentrically. The pipes will be perforated (made holes in) perpendicularly to the inner pipe axis. The perforations have a known phasing and density that will be true for the inner pipe. But due to the eccentricity of the pipes, the holes in the outer pipe will be random. What I want do do is to use Inventor to "unfold" the outer/larger pipe surface OD, to trace the holes down to a flat plane or surface. Then the plan is to print out this flat surface on a paper, wrap it aroud the pipe and drill the holes manually. Please find attached pdf that will help you understand my frustration. Can you help me with this? Please ask if you have any questions. casings.pdf
  22. So I have two 3D scans of a retaining wall (one from 2013 and another from 2014) and I need to compare the two and see if it has moved. I am wondering if anyone in the world knows how to do so. Since the surfaces are vertical, and not horizontal, this has become a real 'head-scratcher' for me. I've tried to use the 'X' values as elevations, but since the retaining wall is not due east-west in the 'real-world' it isn't along the 'X' and 'Y' in AutoCAD, therefore when I tried to compare the surfaces, I get a gradual increased elevation difference from South-North due to the rotation from North (in the real-world) and the coordinates produced... SOMEONE PLEASE HELP, I CAN PAY!
  23. Hello, If you are looking at plan view, I have a bunch of points surveyed for blastholes: x x x x x x x x x x x x x x x x These points all vary in height. I have a surface created under hole collars representing the chemical contact between two different rock units. I'm trying to project a line from the collar of the blast hole, vertically down, to intersect with the surface and determine that length so I can inform the drillers what depth the holes need to be drilled to. Currently, here's my workflow to get the required depths: Survey the blast hole locations prior to drilling. Come back to the office, import my points from the survey to CAD. Determine the extents of the blast. Extend the existing geologic model to determine the hypothetical depths. The drillers then drill sample holes to determine the depth of the surface and the surface is updated within two days. I then need to go back out to the blast holes and use my survey equipment to stakeout the DTM. I then go back around to the holes and record on scratch paper the depths to the DTM. I then come back to the office and annotate the drawing with the required depths. I then finally plot the drill instructions for the blasthole drills. I appreciate any and all help!!
  24. 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 data into Civil 3D 2014 as TIN Triangles, used convtosurface, and attempted to export as an igs. The export functioned but the file won't import into the other program because it requires a watertight solid geometry. I have tried surfsculpt and convtosolid as well as to create a mesh but I am sure I am giving it invalid commands because it keeps crashing the system. Please help! This project needs to be done asap and I am utterly lost. Also not working for me is the manage attachments section on this forum so I have uploaded the files to an open google drive folder: https://drive.google.com/folderview?id=0B6zt3I2EQtAVRHJ4QmVJVW1NUUE&usp=sharing I have attached the .dwg file I have been working in (FromIGS_WithSource.dwg) as well as the original exported TIN triangle file (ZJKCAD4_4_2.dwg), the non-functioning igs model (ZJKCAD4_4_2.igs) and the raster grid file of elevation (whole elevgrid folder) in case any file is more helpful. I have access to Civil 3D 2014 and AutoCAD 2014. Please don't hesitate to let me know if there's any additional information I can give you. Thanks in advance! Zach
  25. Hi Guys, wondering if you've ever had this issue and have figured out what/why my CAD keeps crashing, and if there are any work arounds/fixes for it.. I have a few different surfaces I've created from lidar and survey data, and they keep crashing my AutoCAD especially when I'm switching between layout tabs, but really doing just about any command haphazardly... I know it's the surface because I can set it to no-display or just turn off the layers and i'm smooth sailing, but with it on i usually crash within 10 minutes. I have a pretty killer computer and it's not that incredibly large a surface, so I'm wondering if it couldn't be something else that's bogging it down...I've tried a few different things but nothing seems to help. getting a littttttttle annoyed, and I've done everything else on the drawing but can't seem to finish because this guy keeps crashing. Any help would be greatly appreciated! Running: Civil 3D 2012
