AutoCAD Civil 3D :: Can Hand Draft Small Complex Areas That A Corridor Cannot Handle Easily
Jan 15, 2013
I've read that it is possible to "hand draft" small complex areas that a corridor cannot handle easily.
I have an intersection in an old neighborhood that is constrained by retaining walls, buildings, and so on. In this I have to fit in current ADA ramps. Due to constrained space I will have to get creative in my elevations and layouts.I'd like to somehow integrate it with the corridor.

I am using corridors to model a driving course. I have attached two images that show 2 scenarios. One is where an alignment loops back onto itself. The other is similar to a merging lane.
What are the best ways to handle these? I am having a hard time with the surfaces overlapping. I have tried using targets, but they don't work well.

I have a complex intersection of three corridors with:
- oblique angles
- different sections assemblies (one way and two ways - full section)
How should be the best approach to solve it?

I've been trying to hatch a complex image with a single pattern, but with different stroke weights.
Here I added an image of a simple greyscale image with below the hatching that I'm trying to make. In short: I want to use only 45 deg. hatches in this direction. However, based on the grey value, I'd like the hatches to have different weights.
However, since this image is quite simple, only four different weights were needed. However, I'd like to know if there is an easy way to do this for complex images. For this image I just used pattern fills with different stroke weights, but I'd like a smoother and easier solution, preferably one where it would be possible to have many different weights without having to split up the image in thirty different parts and making thirty different pattern fills.
I'm not sure if this is possible, but I might be overlooking something. If it would be possible with a plugin, I'd like to know too. Even if there might be a workaround via Photoshop, and the end-result would not be a perfect vector, It'd be fine.

I was sent a complex illustrator file recently that contained a lot of distress patterns and points that is basically impossible to work with. It takes 10-15 seconds just to select or deselect any of the objects. I'll I need to do is move the art around a little and resize stuff, but it's taking ages with the lag. I'm using CC on Windows 7 64bit. What options are there to work around this? Is there a way to tell Illustartor to stop rendering, so I can just move stuff around without it lagging so bad? I thought the new engine was supposed to be faster and better at rendering.

I have created a surface from a corridor. I set the boundary of the surface to the daylight of the corridor. In some areas of the corridor the surface does not triangulate see attached.

Copy a corridor successfully? I'd like to try this just a little worried about the explosion of evil this may cause to my Civil 3D session.
Even all the properties of the corridor setup from one to another would be useful. I'm building one corridor and an 2nd one that matches everything except I need to replace my Assembly with one meant for stripping.

My corridor surface is not matching my corridor top links. see attachments. this is affecting my volumes!
The section-plan(surface red).png is showing the section editor and the plan view. the red highlighted line in section is the corridor surface and as you can see in plan view the surface is incorrect and wiggly.
The pdf is all my sections with the red linework being the corridor surface.

When creating multiple sections using the draft option what settings control how the sections are placed? For example, 5 across, 4 down.
edit - I have several alignments. One that has 8 section views is created with 4 across and 3 down, another with 18 sections is created with 5 across and 4 down and a third with 34 is created with 6 across and down. I'd like to be able to control this if possible.

I am tring to grade a complex object. Please see the attached document. The two grading objects are not interfacing correctly when graded although i can get the surface almost correct i beleive. Is there a way to remove this issue or the grading will not create a lot of difference when computing the volume clacs ( we are talking volum computation roughly about a million cubic metres cutting).

Sometimes when I select a polyline with many vertices (extracted contour line) Civil 3D 2011 almost stops working. I have tried locking the layer, but this still slow to a crawl.

I used to be able to hatch most anything without problem. Now with Civil 3d 2011 anything more complex that a box or a circle AutoCAD will not find the boundary even when the quick preview seems to find a boundary.
I've tried overlapping the lines and then trimming. I've tried extending to the other lines. I've tried setting the tolerance to 1/2". I've checked that the lines are snapped to endpoints and meet cleanly.
In testing I've found that sometimes it will find the boundary, and other times it will not even when nothing has changed? Noticing that they have to try multiple times and methods to get C3D 2011 to hatch correctly?
The attached file shows the different results (boundaries extracted from successful hatches) that I'm seeing, and sometimes can't find a boundary at all, sometimes it does. Seems to get different results when I regent and at different zooms (not sure if that's the correct terminology?).

I have a modeled right hand part and a detail drawing of that right hand part with a pin that defines r.h from l.h. and I would like to save them as a left hand part then change the model by reversing the pin. How would I proceed with this task?

Trying to calculate a catchment area to allow me to size some culverts using Civil 3D 2012 Sp#1.
" The specified location results in a Catchment with no area."
After sitting for 15 miutes I keep getting the above message. The surface is huge and there is an obvious catchment area (or I think it is obvious). The surface was generated from contours and cover an area of approx. 8Km x6.5Km but the catchment ares should be around 15-20% of that area.
I tried another one upstream about a Km and it worked fine. So the one I am doing now should encompass the upstream area as well as from that point downstream to the Discharge Point.

I'm working on a windfarm access road (5m wide with widening at bends to 8m) and I need to identify the areas of widening.
I've got the centreline alignment and created the 2.5m offsets to each side. I have also created widening on the insides of the bends using the widening tools and used a linear taper at entry and exit. I now need to hatch up the portions where the road has been widened to demonstrate compliance with the specification and the only easy way I can see is to export to autocad and use the hatch tools (not tried to hatch between alignments).
Whilst this works it isn't dynamic so if the alignment is adjusted the widening alignments are also moved but the hatching remains.

I have a bunch of polylines I want to display the areas for. I am using mtext and fields. However the fields format part always defaults to a less than desirable format. Is there a way to set the formatting how I want it for the entire file? Or is there a better way of labeling than fields?

see attached graphic
simple road widening section
subassembly from centerline is LINKOFFSETONSURFACE out to a target alignment
next sub is good old LANEINSIDESUPER, using depths for PAVE1DEPTH and SUB-BASEDEPTH
the corridor definition under SURFACES specifies top links for both PAVE1 and SUB-BASE surfaces, but they appear to ignore that and cut across the road (see graphic) making a mess of it
do I need to add a link code to LINKOFFSETONSURFACE subassembly? other work-around?

I have a 100 acre park that I am doing earthworks. I have 1 proposed and 1 existing surface. The park is now broke into 5 different areas and I need to get cut and fill for each area. Is there a way to do a volume report for a particular area? I could define the area with a polyline. Or do I need to copy the proposed surface and start chopping up into 5 areas?

when I created a Top surface, C3D showed me otherwise. I need a gap at an intersection. In the attached DWG the intersection corridor has been removed from view by isolate.
I used 2 seperate baselines to force the road corridor to have a gap at the intersection.
Looked OK .. except ..later .. when I created a Top surface, only the first baseline is used to create the surface, the second baseline is skipped : (
I obviously did not make a gap correctly. What is the correct way? Or.. is there no way .. must the designer create multiple seperate corridors when the road has gaps?

I am trying to get the cut volumes for areas that are greater than 15ft of cut for my project. We know that we will be able to get the top 15 feet with heavy equipment but will be drilling and blasting anything greater than 15 feet of cut. This is a different pay item, with greater cost so we need to quantify it.
I've got a composite surface that graphically shows me the elevation bands so I can see the areas that are greater than 15 feet but I'm not sure how to quantify the volumes.
Currently using C3D 2012 with the volume dashboard extension. Have 2013 installed just haven't jumped over yet.

I have a very basic question about creating corridors. As you can see on the attachment, i created an assembly consisting of ditch and my own polyline subassembly and turned it into a corridor. The ditch part is drawn out correctly, but the other part (supposed to be a gravel road) has only sections in certain points.

I started playing around with 3d dwf's. I'd like to share my corridors in a 3d dwf viewer or something similar but when it opens in design review, everything is skewed/ jagged/garbled. The other problem is that it exports everything (assemblies, alignments, sections etc.) so it make viewing navigation difficult in the viewer for people that aren't CAD savvy to begin with. It would be ideal if you could select what you want to export similar to exporting a wmf file.
How do others share 3d models with non-cad people?

We are trying to edit a small portion of an existing corridor by adding a generic daylighting subassembly. The add subassembly tool in the Corridor Section editor works, but we get an error because the new sub doesn't have a target surface specified. how to add a target for a sub that is added after the corridor was created?

When creating an alignment from corridor feature (ditch invert level), the created alignment is not following the selected line (see image bellow). The alignment seams to be created from the first point of the feature line to the last point and ignores all the other points. The vertical alignment created at the same time seams to be correct.
