I've attached a screenshot of the issue I'm dealing with. I have a closed polyline and when I first hatch the area it appears to be correct, but then I'll go do another command and then the hatch seems to extend beyond the boundaries of the polyline.
View 3 RepliesI have survey data of the inside floor of a pond ( the pond has a flat floor ). The surface made from the survey data needs to extend to the outline of the pond instead of the outline of the survey points.
I tried the smooth surface method of kriging with a grid base and I sellected the outline of the pond for the output region and that worked somewhat but there are still gaps between the boarder and the surface.
I have a hatch (ANSI31) enclosed by a closed polyline. Whenever I change the hatch from ANSI31 to GRAVEL some of the hatch shows up outside the boundary. The Polyline consists of both arcs and line segments, and the hatching errors are occurring within the radius of the arc segments. Changing it from Associative to Non Associative makes no change.
I am using AutoCAD 2011.
i need to know if there is any way to control the points in the point cloud.
1. either only import the point cloud in a polyline area i specify
2. add all the points within a boundary not limited to the pointclouddensity = 100, freaking default is 15 almost cost my job today. extremely stressed out right now.
i am talking about extreme lidar surveys. 1km 1km LAS/0.5m contours/xyz files times 355 of them. covers a 2km wide corridor. but i only need 100m wide after i define the road alignment. no need to have all the extra points.
right now i densify the heck out of it and end up like 5-12m points. decent but not good enough because the geotech is bitching about that accuracy is not good for some feasibility study. or is there any software i can do this besides civil 3d.
what i want can also do is automate the 'add points to surface" under point cloud and have the software do multiple boundaries without having me baby it over the night. right now every click is 5 minutes and adds like 400k to 1 million points. Civil 3D 2012
why I get an error trying to hatch this. Its a closed Polyline.
Hatch issue.dwg
Edit: Or rather its 4 joined polylines.
I have a problem in that a customer drawing, actually several cutomer drawings are not closed polylines. tHEY ARE REASONABLY SIMPLE PROFILES THAT i NEED TO CUT OUT ON A CNC ROUTER. mY PROBLEM BEING THAT AS THEY ARE NOT CLOSED the router software will not recognise them properly. Is there anyway to find out where exactly on the profile the gap is with zooming right in and panning around?
View 7 Replies View Relatedevery time I try to hatch it come up with ‘Unable to hatch the boundary’ and it does this with all hatches except the SOLID hatch, why this is!
View 5 Replies View RelatedI wish to hide my associative hatch boundaries. Is this possible to do as a permanent rule?
I have seen that you can apparently put them on a different layer then turn them off.
I used the select similar command but it chose all polylines (which i guess is what a hatch boundary is?)
In 2010 I would select hatch, and then just drag grips around to where I needed them. Now in 2011, I select hatch and don't get the grips. How do I turn those grips back on?
View 7 Replies View RelatedHow to hatch the edge boundary of the texts ?
View 6 Replies View RelatedI am trying to find a command that will hatch the inner edge of a complex closed poly line, rather than hatch the entire area inside the poly line.
When I have simple shapes such as a rectangle I create a smaller rectangle inside the first that is 1' (or whatever I want my hatched area to be) smaller on all sides than the first rectangle. I hatch by selecting the two rectangles; I change the "Associative" hatch property to "No" and then delete the inner rectangle.
My problem now is that I have a complex closed poly line that I would like to hatch the inner perimeter with a set thickness, say 1 foot. Is there an easy way to hatch a inner boundary of a closed poly line or to recreate a scaled down copy of the poly line that is a set distance smaller all around. I hope I have conveyed the question clearly enough.
Annoying time spend waiting while acad automatically detects hatch boundary? - usually a boundary of some sort, thats completely useless anyway.
I'm seeking full control and want to select the boundaries myself and hope some of you can tell how to switch off or avoid this automatic process of boundary detection that usually follows "h" ↵ ( "hatch" ↵ or "bhatch" ↵ ).
i am trying to put a hatch down and am gettin this error 'Valid hatch boundary not found'. now am quite sure the area is enclosed so as far as i can see their should be an issue. the areas autocad is referring me to are are link together and have been replaced but i still get the same issue, when i max out the zoom their is only a tiny dot

Is there a way to Generate only the perimiter boundary, without the 'islands'?
I have a line drawing from a draftsman. It was imported from some other program, but I'm not sure which. However, this has cropped up many times over the years on my drawings as well as others. It just is typically quickly remedied with a workaround.
The hatch spacing too dense issue requiring me to break up the area: this problem will occur on equally sized areas at the same zoom factor at which I just hatched an adjacent area. I have changed the "MaxHatch" variable environment from stock at 10k, to 100k, then to 1,000k; yet the problem persists. I don't have a particularly fast machine so by that point I decided there was no need to max the variable at 10,000k. There are no z variables in the drawing though it appears, almost randomly, to have plines or lines along the same length of wall.
The second issue is the closed boundary. This occurs on lines that are connected at all corners, even when I stretch and reconnect a line, though that is a very time consuming method. When I increase the hgaptol variable it will hatch bizzarre areas that have no relation to what I am attempting to hatch. This is also occuring even inside a REC that I created just prior to hatching due to error on the original layout. I have to hatch an object rather than select an internal point. It has become so obnoxious in this drawing that I decided to post with these questions.
“More than 10000 hatch boundary objects are selected”,
In the attached screenshot, I wanted to make hatch for the indicated boundary but I got the message shown in the second screenshot (“More than 10000 hatch boundary objects are selected”)

I have several days of experience with Autocad 2010... The problem: I have many (a lot) polylines in my 2D drawing that are adjacent to each other, but not joined. What is a good way of joining them, so that those that "touch" each other become one? Maybe I can hatch the area, then delete polylines and then reconstruct the boundary?
View 9 Replies View RelatedI used a 2d polyline to create a surface boundary for a surface created. The polyline is a closed loop. For the boundary type it is outer, unchecked Non-destructive breakline, and mid-ordinate distance = 1.
My problem is that when I do this I only get a small portion of the surface to show up within my surface boundary. If I don't have a surface boundary the entire drawing surface shows up no problem.
The purple polyline is my boundary and the light blue is the surface created within the boundary.
I would like to extend a surface to a outer boundary. When I use kriging to do this my surface becomes too inaccurate, the attached picture shows what kriging does to the surface. In the picture notice the elevations of the surface, you can tell where the survey points are because they are lower than the surface around it. All I need to do is extend the outer points to a boundary and leave the rest of the surface alone.

2013 version. Long story short, I am having problems with pressure networks in my drawing so to simplify things I want to just show the top of the current watermain in my profiles because we are not doing anything with the water main, though it needs to be shown in the profile. To do this I created some points where the watermain is and made their elevation 1.8m lover than the existing surface at those points (due to the 1.8m of cover the watermain has).
I then created a surface using those points and an outer boundary surrounding the points. For some reason the surface stops at one point and doesn't continue to the rest (about 5 more points). So when I create my profile the surface stops short. The points are included in the point group the surface uses, and the outer boundary doesn't cut them out either. Not sure why the surface isn't referencing those points.
We've had a little nagging problem that we've just been living with, but getting a little tired of it: when building a pipe network the plotted line will stop plotting at the outter wall of the structure, thus leaviung a gap between the pipe and the structure. On a 48" manhole it's hardly noticable, but when the manhole gets larger, so does the problem. Check out the attached pdf and you'll see what I'm talking about.
I've been through all the style setting I can think of, but I thought there might be a variable to take care of it...like the FACETDEV variable for crossing pipe.
How to choose “no color” for the line extending between the contours labels?
I labeled the contour lines but sounds that it draws a line between them. Is there a way to hide this line to give it “no color” to have a better presentation for the entire map?

Is there a method to obtain the overall Site boundary? I have not found one, if there is, but it would sure come in handy when creating reports. We must always include the project Boundary as the first item in a report, so being able to add it to the existing reports would be a huge timesaver.
View 6 Replies View RelatedI have alignments that go in and out of a surface boundary (this is because I have a surface that represents the bottom of pavement.) I want to show the surface profile with the gaps in the profile view (where there is no surface. However in the profile view the gaps are sometimes connected with a straight line instead of being blank.
How can I have a surface profile represent the bottom of pavement properly? (An alignment that is not fully withing the surface boundary.) I know I could add the profile multiple time with different start/end stations But, I don't want that, I want it to be dynamic, as the alignment will change.
I would like to show the title boundary of our site on a profile in a way that is dynamic. Same idea than on cross sections, where you can create an alignment running along the title boundary and then show a block where the boundary lies on each cross section. I know I could project a cogo point where the alignment intersects the boundary.
This method is not perfect because, if the alignment changes and, therefore, the intersection point with the boundary changes too, the cogo point won't follow the alignment, staying at its original location. Hence, I'll have to update it manually. I tried using a feature line, but it seems I cannot show a marker only where it intersects the alignment.
The odd shapes are outside the daylight line. They follow a straight-line around the daylight limits (see third attached file), apparently triangulating unwanted areas. I've used a corridor shrink wrap for the surface boundary.
What is the best bet? I'd rather not draw a polygon along the daylight line and use it as a surface boundary, since it could change. Setting a max triangle length in the surface does not seem to provide a desired result.
I have problems applying an Outer boundary to eliminate a small area within a big surface (and a few Hide boundaries within that Outer boundary): Civil 3D somehow creates extra triangles within my surface (that don't really make sense to me). I am applying the boundaries as non-destructive boundaries as I need the surface to extend all the way to my applied boundaries. The surface needs to be untouched (except applying a few Outer and Hide boundaries) as it is design data.
View 4 Replies View RelatedWhen I create a corridor surface I usually create a suface boundary automatically by daylight.Half the time this works fine, half the time it doesn't work at all. If I view the corridor in 3d view it looks fine.
I tried to create a shrinkwrap polyline to use as a boundary but when I picked the corridor in the shrinkwrap command
it locked up my computer. These are just simple corridors with no intersections. Why the automatic boundary only works intermitently? Is there a better/easier way to create the surface boundary?
I need to adjust a surface boundary. I need to remove a corrupted area in my surface. I do not need it. Is there any way to drag a boundary so I can exclude some of my contour area? Is there a command under settings on tool space that I may have overlooked? This surface was furnished by a client so I do not want to rebuild or alter except to exclude some contours.
