AutoCAD Civil 3D :: Triangles Not Seeing Break Lines
Apr 17, 2012
Putting in a simple berm crest, and the triangles skip right over a certain section. Swap edge does nothing and adding points seems to make things worse. I have been able to fix this problem before, but only by deleting my surface and then putting all the pieces back in at once. Then it's perfect.
I think part of the problem may be that the "Contour help" I put in at the blue major contours is screwing things up.I have had the same issue when putting in down-slope channels as well.
I am running Autocad Civil 3D 2012. I created a figure prefix database that our surveyors were familiar when coding in the field. It is a numeric code list. I received a survey last week that had 6 break lines coded in the point file. Only one of the 6 acts as a break line.
All break lines start and stop with the right line work commands but they fail to break crossing triangle legs. I've checked everything I can think of and the setup looks correct . The only difference between the one break line that works and the others is that break line has sequential point numbers while the other break line codes are scattered throughout the point file.
When adding break lines to a surface, a dialog box like appears that asks for weeding factors and supplementing factors. What I would like to know is, how can I change the defaults to reflect the settings needed on my project.
I have created a drawing of a jug from a CAD learning manual, however when I enter HIDE mode the tessellation lines show as triangles, not rectangles as shown on the image in my book.
It appears fine before HIDE (horizontal and vertical lines only) -- I've tried FACETRES but that just creates a higher amount of triangles during hide.
Is there a way to adjust how it's shown in HIDE mode?
I have attached 2 images (or tried to!): 1 - Before HIDE. 2 - After HIDE.
Whenever I try to use the "DWG to PDF.pc3" driver, I'm getting TIN triangles in my PDF. They don't show up in the "Print Preview", just in the resulting PDF. They also don't show up if I print directly to a printer. Only in the PDF. Never saw this before installing SP2.1.
I am running 2011 c3d on windows 7 with 15 GB of ram.
An error message I get is "reading triangles from file" and the program locks up to where you need to do a reset on the computer. I have an existing ground surface that is data shortcut into the file I am opening when I get this error. The existing ground surface is about 5 mg in size. I'm not sure if this is causing the error.
i am trying to add as a breakline. i have not been able to get this particular line to work as a breakline and the surface keeps drawing triangles through the line like its not even there. The figure properties show that it is a breakline. The figure prefix database brings the line style in as a breakline from the start.
Who can tell me if Break lines in Inventor 2012 will be constrainable? I mean come on... All the new fancy stuff Inventor gets every year is great but when will the simple things get done?
Today I opened a file that has previously worked perfectly well, only to find that when I open my surface in Object Viewer and begin to rotate it manually, the triangles making up the surface do not appear. I have the contour lines and border (what is enabled in the Edit Surface Style/Display/Model tab) although the triangles (which should be displayed as well) do not appear. Other surfaces show like they should.
Is there another option other than the Edit Surface Style/Display/Model tab and the VISUALSTYLES command?
I have a part that when I adjust its length additional fabs are needed. Now in my idw for this part I want to secure the break lines on the part at a exact distance from the end / each other to display these fabs. Is there a way to parameterize or set the break lines so they adapt to the change in length and move accordingly?
I used the "break" command to split some lines into segments, but now I can not join them again using PEDIT. They are all on the same elevation. What is preventing me from joining them? I've attached the file in question, I'm trying to join the red (metal layer) lines.
does Inventor offers any option to break geometry lines in drawing behind the text (e.g. notes and dimensions)? I tried this in IV 2009 as well as in IV 2011, but the result is the same in both version, shown on first image. The text is sometimes difficult to read when it is crossed with geometry lines.
with the Genio Exporter. I need to export the surface triangles from my job, but the Genio export dialouge box only gives me the option to export suface boundaries.
I used the function paste to combine three surfaces in one. It could represent a highway. I noticed that when surfaces cross or pass close to each other some extra triangles show up trying to stitch together the surfaces. I can not find an option that can stop this, eg "not create extra triangles". Why these extra triangles occur? Can you limit it?
When cleaning up a surface, I've always created an Outer Boundary to define the surface limits so that the triangles wouldn't go where I didn't want them.
I'm trying prepping in hopes of sitting for my Autodesk Civil 3d Certification exam at AU. The chapter I'm currently reading through talks about deleting triangles from the surface.
So now I'm wondering about the pros and cons of both methods.
a routine that has the option to break vertical or break horizontal, depending on the option, the lines that cross either the horizontal or vertical (again, depending on the option) a specified distance (say .05) on either side of the line you wanted to keep. So if I choose BREAKH, the vertical lines that I choose would break any horizontal lines that cross them. Same applies to BREAKV. Hopefully I communicated clearly enough.
What I would like to achieve is a section band style for bulk earthworks and simple access roads that shows the design level at Grade Breaks only. The problem I am having is that Grade Breaks are being recognised as where the sample line crosses a triangle, not where the the grade actually changes/crosses a feature line.
A have a number of simple platforms, that I have created using an infill from feature lines, usually these platforms are surrounded entirely by feature lines of the same height. As to be expected, Civil 3d creates a few flat triangles, and as a consequence, all of the points where the sample line crosses these show up on my band style. Is there any way to achieve this band style?
I am using the default Revit break lines in a few of my plans, and they work great. But when I insert them into an RCP, the masking region does not mask anything. Tried send to front/back, copying, inserting new. My other masking regions will still work as they are supposed to, but this break line does not.
Has instances where you set your tolerance for the maximum triangle lenth to say 50m to reduce the amount of triangles along the edge that run at long distances. When I do this I end up with multiple surface holes and I'm not sure why as there are points in the area.
I thought well maybe it's because i should've reduced my max triangles first then added breaklines. Would this matter? I also thought I could add a line to the surface to fix the holes vs. deleting surface lines along the entire edge of a surface for many many miles.
I have made an exploded view and placed it an a drawing. I would like to view inside one of the bodies to show where the exploded internals sit, however when I do a break out of the body the trail lines from the exploded internals also get sectioned. Is there a way to control the sectional properties of a trail line?
I have a profile set up with a surface an alignment and a Water Main. I would like to place grade breaks (Using Profile labels) every 100' along the surface however the increment field isn't available for grade breaks. Weeding doesn't work because it needs to be exactly every 100' I was thinking of creating an expression for it however I still haven't reached that level of expertise.
I was laying out a vertical curve in the roadway profile. I have a vertical curve of 100' in length, however immediately after that it shows a grade break. I do not want this grade break in my profile, I simply want a vertical curve with two grades on the left and right sides. How can I get 2009 C3D to remove the grade breaks? It would be very uncomfortable for someone to have to drive over these in the real world.
