AutoCAD Civil 3D :: Converting Surface To 2D Hatch
Mar 4, 2013
Is there any way converting surface to 2d hatch ? I am making plan view to show materials used to make my road , to do that i need to hatch all the plan in different hatches ( for example sidewalks - green, paves -yellow, shoulders - brown... ) .
I could try hatching closed polylines made from corridor feature lines , but i get often an error that my boundaries aint closed . SO i started to think , maybe there is a way to do something from surfaces.
I installed a brand new install of 2013 Product Design Suite Premium on a new machine. When I go to run Inventor everything seems to work fine. I make a drawing of a part and export to DWG. That's a requirement here. When I go to open the file in AutoCAD, the hatch pattern doesn't show and it looks like the boundaries for the hatch move to 0,0,0. Very stange and I haven't been able to figure this out. I installed Premium on another machine and performed the same export. Works fine on the other machine. The other machine however, has 2012 installed as well. Could this simply be a bad install?
I'm looking for a lisp routine which will 'convert' number of 2dsolid into hatch. Drawing contains dozens of 2dsolids (solids are on one layer, there are also other entities on this layer) which have different colors, have common verticies and edges. i.e. I want to kind of 'join' solids of the same color and convert them into one hatch colored as original solids and placed on existing layer (let it be layer '0' zero for now). Same color solids can exist in few locations - there is a case to make few separate hatches of the same color (all joined solids should be represented as 1 hatch, should not separate after separate hatch command). There is max of 20 different colors (all of them from ACI index). Solids are not crossing themself or other solids (just joining with 1 or 2 verticies).
There are also 2dsolids with 'zero-area' - represented as a line - those should be erased at the beginning (not to have a line-like hatch).
I have several IGES files that I need to make into solid models. I have been searching for days on how to do it in Inventor 2012 and everyone says how easy it is, but yet I have no luck. This file was created from a scanned mold and then made using a point cloud.
I am trying to convert this composite surface into a single solid body, however when I try to stich the surfaces in the construction environment it always crashes. I have also tried edditing the STEP file import options but it still always opens as a composite surface.
I am having a problem in an elevation view where the surface hatch covers the windows after I apply a Modify Roofline command in the construct.
When I look at the elevation in an isometric view you can see the surface hatch go through the windows. When I refresh the elevations after the construct xref is reloaded after Modify Roofline command the windows are no longer visible.
If I reset the modify roofline command in the construct, reload the xref in the elevation the elevation returns to normal.
I'd like to figure out why after the modify roofline command the windows are covered in the elevation but not in the construct view.
ACA 2011. I would like to copy the "standard" wall style add a surface hatch and display that in an elevation (exterior) view. I have played around with this and due to many different places to edit the materials.
I have the elevations created. When I go back into the construct and edit the wall style do I have to re-create the elevations to see the hatch? Or I think I just have something set incorrectly in the style.
I have created a TIN (triangulated irregular network) of an existing survey in my terrain modelling software (12d Model). I am able to export (save-as) the TIN as 3D Face Triangles for opening in AutoCAD (2012) or similar.
My ultimate goal is to create a solid surface in Inventor. The surface has to be seemless (stitched) in order for me to create a new sketch and extrude to this surface. Finally giving me a part in Inventor that represents my ground. I would then want to use the same process to bring into Inventor all other Civil Design works created in 12d Model such as roads, earthworks platforms (including dams) etc.
I've tried stitching (Inventor and Microstation) without success. Inventor keeps crashing and Microstation looses data. AutoCAD (2012) won't let me create a polyface mesh from 3D Faces. I tried doing a mesh, surface union without success. Programs either crash or data is lost.
I often have to do storm pond surfaces that (for the purposes of planning) are flat on the bottom. These surfaces are created from a combination of survey data and grading groups and the tin of these surfaces is perfectably acceptable. However, when contours are shown, the flat bottom is shown with contours jig-jagging all over the place.
The attached image shows a comparison of the same pond. The top was created with survey data and grading groups; the bottom was created using contour data only. The generated surface on the top shows the bottom contour going in different directions and has parts where the an expected contour is missing.
How to correct/manipulate the surface to show a proper flat surface?
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 am trying to add points into a surface. I have done this before without any problems, but now I am having issues.
When I ID points which makes up the surface it gives me the correct Z level e.g. 24.5m, however when I hover over the surface it shows me the surface name and a different z level e.g. 0.65m. What is the reason for this difference in z levels? I think this may be causing the issue I am having when I add new points.
I select the surface and use the 'edit surface command' in the ribbon, choosing add point.
When I add a point at the level I require(23.89m), it puts it in a lot higher than the surrounding area, so I tried to put the point in to the lower z levels (0.4m) it puts it in a lot lower!
I am issues with DEM files that I am downloading from the USGS website.I download 24k, elevation for the area I need. I then choose staged 1 second, add a surface to a blank drawing, then upload the DEM files to the surface.
The surface imports correcty, but when I try to import points taken by a surveyor on the same drawing, they plot incorrectly.The DEM surface and the points from the surveyor do not correspond. Also, the DEM surface is in meters, not feet. I have tried changing drawing settings, datum types, coordinate types, etc.
I have a project involving 3 programs. I am creating a planned development in 3d to be 3d printed when finished. The project is a 5 acre tract containing 8 buildings. I have built the surface in C3D and each building in Revit. The buildings are not in the same Revit file. For my solid work, I will bring the files over into 3ds Max Design to section into smaller quadrants to build in the 3d printer.
The questions:
Would it be better to import the surface into Revit to merge surface and buildings together?
Would it be better to import the buildings into C3D to merge entities?
Would it be better to bring those entities into 3ds Max and then merge them into one? Will 3ds Max Design allow me to insert entities accurately in the environment?
I need to create a sub-set surface from my main surface. not sure what the vernacular is for a "subset surface" in c3d but i do have a feature line that bouinds the desired area, but that is as far as i can solve.
i did try creating a new surface - pasted the main surface in the edit definition, then deleted triangles until the boundary alighned wiht my featureline. This seemed to work, but when i view the properties of the smaller subset suface, it shows a mimum and maximum elevation that is incorrect.
Im currently using an addon for Civil 3D called Novapoint. It allows me to create 3D models of surfaces made out of 3d faces and easily models cut and fill 3d-models for me.
The only thing i need to create a cut and fill model is one or several ground surfaces (existing ground, earth layers, rock etc. whatever i need) and a closed polyline/3Dpolyline that represents the level I want my cut and/or fill model.
I enter the spcifications I want such as; earth cut angle, rock cut angle, fill angle, select which surfaces i want to include in the model calculation and select the polyline.Novapoint then calculates the cut/fill model from the surfaces to the polyline and models the different cut/fill angles and gives me the results in a 3d-face model and a specification of the volyme of rock cut, earth cut an fill.
1. Novapoint is quite unstable and crashes alot
2. You cant create profiles out of 3d faces
3. Novapoint does not automaticly combine the start surfaces with the modeled cut/fill surface
4. A large surface made out of 3d-faces demands alot of computer power
So I want to how I do the same that Novapoint does for me in Civil 3D? (I have access to Civil 3D 2007-2013 depending on which one you're using)I know I can take the 3Dfaces i created in Novapoint and make a surface in Civil 3D with them but I want to exclude Novapoint completely.
all of a sudden whenever I run audit on my corridor file the surface definition becomes a snapshot. To add to the drama, the corridor surface will not paste into an empty surface. Why?
My problem added with pic ... I want to make volume calculate for sample road project. When I try to compute materials I cant use Corridor surface for DATUM... There is only target surface on option..
I am trying to visualize a road project. The problems is, whenever the corridor surface goes below the EG surface (when the road is in cut) the EG surface is the only visible surface.
I sort of need to subtract the corridor surface from the EG surface, or merge the both surfaces into one.
I was wondering if there is an easy way to trim one surface to another. Right now, I have two slopes (3:1) that are perpendicular to each other. They meet at a corner and I have extended them past each other so that I could see the intersecting edge. Now I would like to trim them to each other like you would a polyline etc... but I am not sure how to do this.
If I select surf trim, it tells me they are the wrong object type, but they are tin surfaces?
I have finally created the shell of the complex surface that you see. This is only a section of the part because I cannot show the whole thing for proprietary reasons. I formed solid surfaces using the network command. The propblem is that it will not convert to a solid because the surface seams are not "water tight." When the network command created the solid surfaces, the surface seams do not exactly match the lines so there are gaps in all the seams. I have tried blending, patching, etc. and nothing works. how to convert this to a solid without losing the outlines and the shape?
I 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.
Is it possible to export created surface from civil to revit architecture? If yes , How? And if its not possible - maybe i can somehow import cogo points to revit?
I have a hatched region that clearly has an area, however the geometry properties indicate that there is no area associated. This a a complex region with many PI's. I really don't want to recreate this area.
Is there any way I can create a boundary around the hatch lines?
This might be simple, but what is the best way to hatch a part of a surface at say RL4.00 only so that any part of the surface below RL4.00 is hatched and the rest of the surface is not.
