  1. I have two polygons. One is my corridor (see white), and my other are disturbances (see red). I'm looking for a lisp that creates polygons everywhere where there is an overlap between the two (see green hatch). I currently have a lisp that gives me the area of the intersecting hatch but it is only a single use. I want to be able to click the white boundary layer and then the red intersecting layer and have it make intersecting polygons between those two.
  2. I have a line that crosses through multiple polygons. Is there a LISP to give me a count of how many polygons this line goes through?
  3. I have recently been asked to learn the Pressure Network part of Civil3D for an upcoming project but there are a couple of things I'm having trouble with. I will need to create approx 25km of water main supply pipe. I have worked out how to create pipes manually and assign the entire line to a pre-designed profile instead of offsetting from surface model with no real problems. But for the length and complexity of pipe involved the "Create pressure network from object" tool would probably speed things up enormously. My problem is that although this tool adds bends etc with ease, it does not seem to allow for pipe deflections at joints. ie. if the bend is actually 46 degrees it does not simply allow for a 0.5 degree deflection at the joints at each end. It instead realigns the downstream pipe and introduces 11.25 bends here and there to fix it's mistake. Also the same with straight pipes that might have a 1 degree deflection somewhere to follow road alignment. Instead of simply allowing the deflection between straight pipes, it introduces an 11.25 bend with deflection at it's joints over and above that allowed in the parts catalogue. Is there a setting or a box to be ticked that I am missing? Or am I destined to do all of the design manually? Any help will be greatly appreciated.......
  4. I'm Labeling flow information of a pipe (RCB to be specific, but I'll use pipe), and almost at random parts of the expression disappear leaving me with an error for the labels and having to go through the tedious process of fixing the expressions. This happens with several expressions but the same information is missing. So for example: HYDRAULIC RADIUS RCB: (AREA_OF_PIPE_RCB)/(2*{Inner Pipe Height}+2*{Inner Pipe Width}) Becomes (AREA_OF_PIPE_RCB)/(2*+2*) It always seems to be losing the information related with the pipe's property. While it does it this when I restart AutoCad it doesn't do it everytime, I cant find to seem to find any pattern to when it does it. I'm new here, I did a quick search and didn't find anything, I asked a few of the veterans in my office and they haven't seen anything like this, so hence I'm posting here. I appreciate everyone's time.
  5. Recently upgraded to Civil 3D 2015 from 2013 but am having trouble using one of my most used AutoLISP commands to connect a string of points (connectpts) When I load the command I get the following error message; "; error: Automation Error. Problem in loading application" Any ideas out there?

  6. I need to turn off the line weights in layout. Civil 2014 had an icon at the bottom just like all the rest of ones I have worked with. I do not see anywhere to toggle line weight on 2015. Please help!

    Google Earth Image question

    In Civil 3D, under the Insert tab, there is a menu selection that allows you to insert a Google Earth image directly from Google Earth. This image is inserted to match the coordinates of your ACAD drawing. However, it does not always match the known correct line work, depending on the drawing settings. For example, if one was working on a project in California in Cal. Coordinate System, zone 2, the available coordinate systems (under the Units and Zone tab) could be HARN, NAD27 or NAD83. Then there is the transformation settings (under the Transformation tab) like: Sea Level Scale Factor and Grid Scale Factor. My question is: What are the best drawing settings to use for the best fit between the Google image and the drawing so that the image matches linework that you know is correct (based on certified surveys)? Thanks.
  8. Hello all, How can I create a smooth transition between subassemblies with different daylight slopes? I have a corridor with 2 subassemblies used. I set the regions up so type 1 is from Sta. 0+0 to 0+100, type 2 from 0+100 to 0+125, and then from 0+125 to end is type 1 again. The daylight slope for type 1 is 1.5:1 and it is 100:1 for type 2. Thanks in advance, Kyle
  9. I'm wondering how to generate curves for alignments based on monuments. Say I have two monuments tha represent the start and end of a curve. The old method is to draw two perpendicular lines from the monuments and draw a circle with a radius where those lines connect. What is the new way using Civil 3d? Thanks.
  10. I've got an assembly of a crown road and daylight sloping running along a corridor. At one point there is a retaining wall along the shoulder which I want to daylight to (the rest of the road daylights to the original ground). I've inserted a "LinkOffsetandSlope" subassembly that will do what I want in the area of the wall (represented by a feature line). But for areas of the road where there is no wall, it still shows a link running to the default offset. Is there any way I can make this work without making another assembly and separate region? Thanks...
  11. I am using ACAD Civil 3D 2011 and when you stop the cursor in a surface area, a pop up info window shows data such as surface elevation, station offset etc... The problem I am having is the font is light grey over a cream colored background which I find hard to read. Is there anyway to change the font and background color for this information pop up window? I have tried the accessability options under Windows (using windows 7) with no help. Our computer administrator in our office has blocked some of these accessability options so if it works for you, let me know anyway and I can request our administrator to help me. Thanks in advance for your help.

    Point Label Style in Civil3D

    I have successfully created a whole range of particular settings for labeling my points (which are topos points with the headers of N,E,el) in the Label Style Composer and created a new style particularly for these kinds of points. Actually, i created 3 different Label Styles based on the description of the topo point) My predicament, is that clients will send me their .dwg files, and i have to import the points i collect onto there drawing which obviously don't have all the label styles I just learned to create so the points don't label correctly and i have to re-create all the styles each time?! question: How can I apply my Point Label Styles onto another .dwg? TIA!!
  13. I have finished all my subdiviions designs in Civil3D CAD ( roads, profiles, etc...) and am getting ready to "cut" all my sheets (25 sheets) to be able to issue the construction documents. I have experimented with the Plan Production Tool (Viewframes,Sheets,etc...) I like the fact that it can actually get the profiles legible at the right scale,etc... I like the automated features: Matchline Text,etc... QUESTION: Does any consulting company REALLY use this "wizard" or is there a ? QUESTION: How can I "edit" the SHEET TEMPLATE that Plan Production Tools is using (I have my own customization I would like to do)...How do I access ALL the Settings for the Plan Production Wizard ? **NOTE: I feel that the rest of the Civil Engr Indutry is NOT switching to Civil3D but sticking to the LandDesktop Transition..... After several months, I am finally convinced that Civil3D is more flexible....I am all alone in trying to create Construction Documents with Civil3D ?***
  14. I am getting ready to perform a CLEAN install of Windows 7 (to replace VISTA) Are all the Civil3D 2011 "Database" (Surfaces, Alignments, Style Settings,etc...) sotred within each .dwg file, or is there a master database faile ? I am NOT using AutoCAD Vault Any tips on the reinstall to be able to get all my settings, plot style EVERYTHING, back to where they were ?
