View 1 RepliesI am creating some simple grading objects from feature lines. I am targeting my existing ground surface with a 2:1 fill slope. My resulting surface shows me 5' contours, which I think should all be spaced out at constant 10' offsets, but they are not. When I measure the offsets I get different values ranging on 10.2' to 9.7' (depending on the section of the feature line I am looking at). How to make the slope build properly with a true 2:1 offset between contours? What good does this grading tool do if you can't get a properly constructed slope?

Why i am not able to select the area?
I have a compost pad and retention pond to design, I set my back Pad line to surface and then graded to elevation so the slope to the pond will have no cuts
I created a pond and left out the grading to surface on the up hill side towards the pad which will be paved one day. I now created two side feature lines to enclose the whole pad and graded by distance and slope.
My problem now is the two side and back seem to blend together as I attached the feature lines together but I can not figure out how to blend into the pond create as it has side slopes to EG and the front which must join to the side slope crest to enclose the pad to drain into the pond.
It has been too long since I created Grading Objects and Proposed Surfaces. I am working in a file with my existing surface DATA Linked. I am creating a grading plan. I have created three separate grading objects in the Site named Proposed. One in the building, One is a new ditch, one is a graded existing ditch. I need to make these three with the unaffected areas of the existing surface into a new surface. How do I accomplish that . All my grading objects appear to be individually accurate and are created with a Feature Line and Grade to Surface Styles.
View 1 Replies View RelatedUsing 2010 with update 1 or whatever it's called these days, I'll just call it the first fix.
I've made three grading objects using "Grade to Relative Elevation" along a feature line. Then I've added a grading transition between them. This seems really unstable now, like making the wrong move makes the whole thing disappear...but what is strange is the feature line that is attached to the grading object that I have added into my surface remains, but there are only a few lines where the grading objects used to be, basically the line that seperates the different sections of grading.
There's no way to edit the grading again either, it has to be remade, because there is nothing to select.

I have been creating grading objects from my curb lines, assigning grades using the editor, then offsetting that line for the BACK of curb, and using the raise-lower command to raise the curb line height. If I edit the original face of curb line (gutter grade) then I go back and redo the process. Is there any way to intelligently link these two lines so that if one gets edited C3D knows the other is 0.5 feet higher (or lower) than its neighbor?

View 3 Replies View RelatedI have a Proposed Building Pad. Grading is 3:1 on 3 sides. Grading is 5:1 in the front of the building. How do I get Grading to fill in the area at the building corner between the 3:1 and the 5:1 grading? I thought infill would accomplish this but it seems to have no effect when I select the objects. I included a screen shot and the area at the left corner of the building.

I understand I could possible to a create grading feature line for a stoop, but what happens if the stoop would be irregular shapped and not a rectangle?
View 5 Replies View RelatedWhen creating Feature Lines, I wanted them to be e.g. Step Line 1, Step Line 2, Step Line 3 etc so I amended the name template to suit. I created multiple from objects and the naming convention worked. If I did features individually (as I wanted certain ones in certain sites) it worked for the first feature but reverted back to the default Feature line name on subsequent entry to the dialog i.e. it had "forgotten" the template name just set.
Am I missing something to get this to work correctly or is this how it's supposed to work i.e. useless for individual feature line creation?? This also happens for gradings.

"An infill grading has no criteria applied to it. Any area bounded by feature lines or lot lines that is not already a grading can be converted to an infill grading."
So given an area enclosed by a feature line, an infill grading can be created. Using the same features line, an feature line grading can also be created. what is the difference between these two surfaces? They both have no criteria applied to them.
Some background: We have a composite surface of existing surveyed contours as a TIN pasted into existing aerial contours that we received from a client. We used polylines to generate our proposed contours, and then generated a proposed surface from that. We've made a blank surface, pasted in the existing surface, and are trying to paste in our proposed surface... only the existing contours outside of the proposed suface no longer line up correctly once we do.
We've tried applying the method laid out here: [URL] ........ (and the link referenced in the bottom) but are still having trouble getting the surface to work. We've tried offsetting as little as 0.25' and as much as 5' with the feature line draped over the existing surface, but it seemed that the greater the offset, the greater the discrepancy.
Just to make sure we even tried that correctly - should the breaklines that we add be standard or non-destructive? (I've tried it both ways with little success either way, so I don't know if it matters much in this instance, but perhaps for future reference it would work.)
I've attached a screen shot of our surfaces. The pink and green lines are the proposed contours, the white dashed are the existing. The outer red line is offset 0.25'. As I've mentioned, we've tried offsetting various amounts with decreasing success.
Recently I have download Corel X6. It is a beautiful software, but when I combined some objects the holes fill-up. I read about this in forum and found a hint that reverse node. It is a good solution but this solution works on when you are using a few objects. What if I have a full page of objects and want to combine them. It is very difficult to select each object's node and apply reverse node command.
In Corel 12 it was works fine i.e. combining objects. But in Corel X5 and X6 it is work like a ghost.
i'm exporting a surface from 2013 to be used in 2010 for presentation. works great but the contour interval is not the same as the surface i'm exporting. working in 5/25 contours...xml import comes in with 2/10 contours. looked for a setting but can't seem to find.
View 2 Replies View RelatedI'm drawing a topo and trying to figure out a way to manually smooth out my contours. I'm not talking about the little jagged edges that you can remove if you use the smooth surface option under surface properties but the big ugly looking jumps you see when contouring a relatively flat lot. In the ancient version of AutoCAD my company used the contours came in almost like splines and you could move the vertices around to make them look good. I know you can go in and delete some TIN lines and edit point elevations but that is very time consuming and I'm hoping there is a quicker way.
I know I can extract them into polylines but there are too many little segments to be useful. I've seen the SIMPLIFY SURFACE option and while that takes away some of the roughness it creates some as well. Is there some better option than extracting and then drawing a spline between the parts I want to smooth out? These contours don't need to be 100% accurate, I just need them to look simple, like if someone was drawing them by hand.
I have added contours to my surface (the blue lines). For some reason the surface generated contour (the orange line) is jumping across the contours I've added.
View 8 Replies View RelatedMy TIN surface either did not generate contours or did not display them on my drawing. I created and tried surface styles of many contour intervals(from 0.5' and 4' to 2' and 10') without success. I made sure my contour layers on both the Style Dialog box Display Tab and Layer Properties Manager were turned on, still no success.
View 6 Replies View RelatedI'm having problems contouring in C3D 2014.
I'm using the command PL - polyline to create my break lines (Centerlines, top and bottom of curb)?.
In this particular drawing the first point I click on is carrying the elevation throughout the entire length and yielding bad contours.
Essentially the bottom of curb on each side of the street should be the same elevation with a crown at the centerline.
Instead the elevations are about five feet different because the beginning point is around the corne at a point of tangency on a hill.
This has not happened in any other drawings and I've done them the same way.
I redid the breaklines with the 3DPOLY command and aside from a few minor edits the surface came out OK.
I've been reading about 3DPOLY command but have not found out too much about what the actual difference is between 3DPOLY and PL commands.
Seems like 3DPOLY is the way to go.
I do not have too much experience with C3D 2014 and am making a huge jump from 2004 LDD. How to build 3D surfaces/contouring.
When I generating contour(surface) using Civil 3D it gives very complicated contours.Some times those contours cuts each other and have very strange shape.
I used to use SURFER software to generate contours.It gives simple contours.But I like to use Civil 3D because.
I attached SURFER contours and Civil 3D contours. I also attached AutoCAD file those who using older versing of Civil 3D.
I know how to smooth contours in Civil 3D but it does not solve my problem. You may say "You should use commands like swap edge,delete line .
We have a total of three machine at our office that are running 64-bit Windows 7 with Civil 3D 2013. Two of the three machines have problems with drawings that include AECC_Contours. When you try and start a polyline or line the mouse will begin to jump and lag. As you move the cursor off of the AECC_Contours the mouse returns to normal operation. I have looked around throughout forms and have yet to find anything that relates to this. Also I have disable Aero within Windows, thinking that may have been the issue. All three machines are running the same version of Civil 3D with the latest service pack.
View 6 Replies View RelatedWhile working in a drawing with civil 3D points and a surface created from those points, once in a while the contours will disappear. The contours disappear during any number of different commands, so it doesn't seem to be linked to a specific set of commands. If we save the drawing, close it, and then open it back up the contours are there with no problems. Is there a fix for it beyond closing and reopening the drawing. We are using Civil 3D 2010 in our office, and all of the current updates.
View 5 Replies View RelatedIm working in Civil 09. I need to adjust the surface I created in order for the contours to be correct. Right now I'm interpolating point elevations to adjust the contours. I find myself adding lines and adding and deleting points. It's tedious. I tried changing the grid spacing to smaller one. It didn't seem to work.

I want to make layouts/viewports that are clipped to different elevations. For example I have a surface with 5' contours. I want to create multiple viewports on a sheet showing what each contour looks like at its elevation.

I encountered a problem while creating contours from the points. what actually is the problem with the points or tell the steps once again that would be great. I'm attaching the points file.
View 9 Replies View RelatedI'm running 2012. Is it still true that I need to label my contours in every drawing? I have a drawing that contains my existing surface (about 90 Acres). I have labeled the contours in that drawing. I then have a output drawing that the existing contours are a data shortcut. The contour labels do not show up.

View 9 Replies View RelatedWhenever I zoom out in a drawing in Civil 3D with surface contours, some of the contours disappear. I imagine this is a result from a system variable setting but could not find it.
View 2 Replies View RelatedThis is the first time I have imported a .dgn file into Civil. The drawing contains contours lines with Z elevation data. When I create a surface using this geometry (polylines + some lines) the surface seems to be scaled in the Z axis by 12.
For example pline (from dgn) is at elevation 46' but the Civil3D surface is 552'
I assume this is a setting in the Surfaces dialog box, but I cannot find it.
Also the elevation field in Properties from the dgn contours is weird. For example, in one area the (pline) contours display -28', 26', -24', -22', -20', -18' in Properties but Civil3D interprets this as a downward slope - which is the actual field conditions. I don't understand the conversion going on here.
The geometry of the pline and contours generated from the surface seem to line up in a side or isometric view (see attachment).
Often I've found myself dealing with some pretty complicated surfaces that have a lot of nooks and crannies, and many of the contour lines are only in a corner of the surface or are small and closed, and thus when I find myself wanting to have contour labels on all of the contours, there's not really one line I can draw using the "Create Multiple Labels at Interval" option to ensure that every contour is labeled. Thus I end up doing "Create Multiple At Interval" with a few different lines intersecting contours, but I often end up hitting some of the contours multiple times and I get a mess of labels.
I haven't been able to find a way to automatically just multiple labels on all of the contours at an interval in one fell swoop, so I started trying to program one...but then I got stuck with that, too.
Does any built-in method of doing what I want to do, or do I need to continue pursuing a programmatic solution?
trying to create a model from existing polylines (at elevation). I have created a surface, went to definiltion, drawing objects, but there is no "polyline" option there. I must be missing something. How can I create a c3d model from existing polylines?
