I want to draw a 3D-polyline and wrap it to a surface so that the elevations in the surface aplies to the polyline. With every elevation difference i want a vertrice to be added to the polyline so that it follows the surface perfectly along the polyline length.

View 3 Replies View RelatedI have started to use CIVIL3D 2007 instead of LAND-DESKTOP 3.
My question is: When I used LDD I created a surface, then drew a polyline and by right-clicking chose "Project object".
This option produced many new points along my polyline which I used for my design.
When I tried this with CIVIL 3D I couldn't find this option.
I can create a quick profile, however, this is not good for me because I need the data as a collection of points with coordinates & elevation, and not as an image.
Is there any way to produce a projection on a surface (from a polyline)?
Or getting some information from the quick profile in the way I need?
I have a proposed surface that has been made by selection polyline with a z elevation as contours. Is it possible to have civil 3d easily change the weeding and supplementing factors to a tighter value after it has already been made?

Is there any way / trick to wrap a 2D sketch to a non-flat/cylindrical/conical face? See attached part. I'd like wrap the lines in Sketch2 to the ring's outer face in order to get a proper path for "engraving". I see no other way to get a proper path for sweep, because project along vector won't work.

I have a picture of a coffee mug.
And I want to "wrap" a circular logo to the mug to make it look like the logo is imprinted on the mug. What's the best way of going about this so it doesn't look like it was a poor photoshop hack?
What I have figured so far is to use the Edit / Transform / Perspective to squish the bottom and widen the top to give the perspective. And then I go to Edit / Transform / Scale and squish it vertically.
Heres what I end up with:

I have created a series of splined lines into a polyline (pedit) which I want to extrude. When I extrude the polyline I only get an extruded polyline and not a surface. I need to create a mesh or make the surface a face to extrude to make a solid. I have not used AutoCad for some years and have forgotten how to do this. I know that I am making an incorrect procedure here somehow.
View 3 Replies View RelatedAny way I can align a new polyline to a reference polyline (orig polyline).
The 2 polys will be generally the same length, however, the number of vertices will differ.
Also I need to mantain the same distance between the vertices on the new poly and the new and reference poly won't follow the same direction.
I am wanting to digitize a geology map using AC Map 3d. When I draw 2d polylines of geology units, I would like to be able to drap these onto a DTM suface so I can have them in 3d. How do I do this?
View 3 Replies View RelatedHow do I go about extruding an open polyline to create a surface? I am able to extrude a solid 3d from a closed polyline ( by creating a region first) but I cant find a way to do the same for surfaces.The autodesk.autocad.databaseservices.Surface class does not have an extrude method unlike the its solid3d equivalent. I am using autocad 2012 .
View 1 Replies View RelatedI was wondering if you could generate a 3D poly line from a surface which I have sliced. I am trying to establish retaining wall heights in a cutting on an embankment. I have generated the slope using 2 3D polylines offset and edgesurfed between them. I then put my proposed footpath at the desired location. When I needed to slice the mesh I had to convert it to a surface. It worked but I now do not have any nodes that I can connect vertical lines to in order for me to design wall heights etc.
Is there a way to generate a 3D poly from the sliced edge of a surface.
I have been using AutoCAD to create product designs (baby bottles) for the last three years. I am normally drawing lines, arcs and splines to create the shape, then I use PEDIT to create a closed polyline and REVOLVE to create a SOLID 3D object from that shape.
Couple days ago, AutoCAD is not longer creating 3D solids when I use REVOLVE as usual (even using older files and/or the same shapes or polylines that I have used before to create 3D solids). The result of REVOLVE is "SURFACE (REVOLVE)" (I got that from properties). But, the most uncommon thing is that AutoCAD is revolving fine one or two times per day after many many tries. (normally I am closing and opening files and trying to revolve some stuff many times, using the same process and suddenly it revolves the sahpe as a 3D solid)
I attached a picture showing two objects created using the same group of lines, splines and acrs. One is a solid 3d object and the other one is a surface (revolve) as result of using REVOLVE command. WHY????
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!
My goal is coming up with the volume bounded by the design surface and the existing surface. I don't have the design surface modeled yet.
Do i need to create alignment offsets?. Alignment 1 profile view is also attached. Then Alignment2.
What about starting with alignment1 profile view? Since I have created a polyline as the design profile ?
how do I shrink labels? Where is it in the settings ; the Align folder had been check.
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.
Is there any way to change the referenced surface on a Surface Elevation Label. I can see the surface in the properties but cannot change it.

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?

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?
