AutoCAD Civil 3D :: Can't Get Perpendicular 3D OSnap To Grab The Solid
Mar 18, 2013
I have a drawing (c3d 2013) provided by a subcontractor that contains high density laser scan data in the form of Acad solids. I have a bunch of conventional QC shots on the same objects, that I would like to compare to the scan data.
I can bring the QC shots into the scan drawing as cogo points, but when I try to measure the distance to the face of the solid, I can't get the perpendicular 3d osnap to grab the solid.

How to turn on the perpendicular osnap. Whenever i open the draft settings window and get close to the perpendicular name it changes to midpoint. I can not seem to select the perpendicular name.

Just found the issue with my AC2013.
A bit of difference is that the polylines do not have to be even closed. Any polyline gives me exactly the described behaviour, which is definitely not intended. Appears still not resolved.

Is there a setting that I am missing where if your osnap is set to node, it will snap to the node if you hover over the point text? I seem to remember this working in versions before 2012.

1. We all understand that designing highways is not simple and I don't know in your country but in my area almost all the bridges come at an angle from the alignment/corridor. Now, how can you do that in Civil 3D ?
2. Can you insert an entire shape, let's say a culvert into the design / corridor and be able to show it in the 3d view preciselly like it will be in real ? what about showing it in profiles or sections ?

I have an alignment going up the center of a draw. I'd like to extract cross sections of this alignment and existing ground. What is a good way to do this?
I don't do cross sections very often, so when I need one, I draw a second alignment perpendicular to the first and profile that alignment to give me a bare bones cross section. I'd like to do these cross sections on a given interval, and at every change in direction. How should I go about it?

When trying to draw or stretch a line or grip along an object in 2013 it does not follow the osnap like it does in 2012. For instance if I draw a line and then want to draw another line from the beginning of that line along that line using the nearest osnap and inputting a distance, the line follows the cursor rather than the snap.

All of my OSNAP settings are reverting back to some default every time I open AutoCAD. This includes the snaps that are auto (I set endpoint, intersection and perpendicular. When I reopen, I get a random medly of snaps like tanget, parallell, insertion ect.) Object Snap tracking also truns off.
The settings in my profile also turn off (eg. marker). I have tried saving the settings to my profile with no luck. All of my other profile setting remain untouched.

I have a pipe network and a profile for it. Some of the structures have 2 inlet pipes. The pipe system more of less goes down a road, so every now and then there is a cross pipe into a structure. I have masking turned on under the structure style->profile setting. I want to see the cross pipe, so I found on here that all I need to do is under structure style->view direction (profile)->make Structure Pipe Outlines visible. I did that and still no cross pipe shows up. If I turn the masking off it is there.

Any way to raise/lower a surface, but is there a way to offset a surface basically 1m (to make it easy) perpendicular to all grades? Because when you raise/lower a surface, if you have a 3:1 slope, it will raise/lower it vertical 1m or so, but then the perpendicular distance between the 2 surfaces is less then 1m.

I am working on drawings where we create dtm's from surfaces, use the dtm for layout, shoot the asbuilt of the final surface, and then compare hundreds of shots to the surface to develop an as-build report.
I want to be able to select a mass of points, compare the perpindicular difference in elevation to the surface, and have an excel spread sheet generated from the results.
My coworkers are able to do this in Terramodel but I am on a mission to eliminate Terramodel from my day to day work.

I have my alignment running up the page, it is the red line. I can show the profile of the pipes and structures that run with the alignment but I want to she the elevations of the crossing pipes, not just the circle in the structures where they cross but the elevation of the crossing structures and pipes, (str 102-103 and 104-105). Almost like a profile that is cut and looks north (up) instead of the cut looking east west.Can I turn my profile view or take a view at a certain station or do I need to make alignments that run east west to do this? I have included a pedicure for reference.

Back in LDT you used to be able to mouse over point descriptions of dragged state points to get Osnap to select the node. Civil 3D has apparently done away with this, why who knows but its very very hard to know what point your selecting if say you have a bunch of points on top of eachother. Can this be enabled anywhere?
The very mundain work around is to use 'PO to select the point entity, but it does not show the little osnap indicator on the point marker when you use 'PO.
How can I get my old Osnap node selection back?

I've been trying to use the automated plan & profile production tools with 2010, but haven't quite gotten the final product I wanted so I've resorted to manually setting up my own "viewframes" to align my viewports with. However, when I snap to either the top right of my profile view or the bottom right of my profile view, Civil 3d automatically crashes. This makes creating closed rectangular polylines to act as "viewframes" around my profile view very frustrating since at some point or another I'll forget to turn osnap off and blam!, civil3d is gone. It only happens with split profile views and it only seems to happen at the right side of the profile. It doesn't seem to happen at splits. It has happened in 2 different drawings. It has happened with different profile view styles.
Update: It only happens when Node is enabled in OSNAP so I can Node and be fine, at least until the next day I forget to disable Node while doing something near a profile.

I'm trying to model a tunnel network and I have come across a problem . The problem is best described with an example:
A sort of tunnel - or shaft - has to be blasted in order to make an access between the ground surface and a certain parking cavern. This access will be an escalator and the tunnel will be blasted in a 30 degree angle to the horizontal level. Normally when I design tunnel cross sections (CS) the contractor will blast the designed CS perpendicular to the designed profile.
I drew the tunnel CS with sub assembly composer and created an assembly in civil. I then made an alignment and a profile according to our design. And here is the actual dilemma: Civil draws the assemblies so that the assemblies are vertical and what I need is them to be drawn / modeled perpendicular to the designed profile. Is there a way to do this?
I will attach a .pdf and a .dwg of a surface profile along the alignment created (and tidied up) with civil 3d, in which I have tried to illustrate the problem in case my description isn't clear enough!

when creating a pipe network, and the slope of the pipe end is say at a 35% from start to end, the crown of the pipe is at a 90 degree angle from the invert elevation (straight up). So if I have an invert elevation of 288.3' the pipe crown elevation is at 292.5'. I need to show the end of the pipe crown perpendicular to the invert elevation so that it reads 292.0'!

I need to place points automatically and in order sequentially along an alignment and I need to generate data from the points relative to an adjacent alignment. SO, two alignments, adjacent but not parrallel to each other. The data would then be point #, sta and offset from the adjacent alignment with the points placed in order and by window or crossing. I have a few thousand to place so one at a time would be an undesireable solution of course.

why a line drawn perpendicular to a spiral curve in C3D is not radial? If so, what is it perpendicular to? It can result in several feet of difference.
Also, labeling an alignment along a spiral using the automatic routines appears to run perpendicular (whatever that is - not radial).
Perhaps I'm not looking at the math right (its been awhile since spiral curves in college) but it seems to me that a curve of diminishing radius should be labeled radially. Is that not how C3D sees it?
The only other thing I can think is that C3D is running perpendicular to the small tangents or arcs that it puts in to approximate a spiral curve.

Is there a reason why the "node" osnap won't recognoze certain point markers? I have recently begun using named plot styles and I have been revising some of our markers to reflect this. I have noticed that some of the point markers (it seems like markers that use a circle as part of the marker) won't show the node marker no matter how I hover around it. Others seem to be normal.

I have a.3ds file imported into Civil 3d. The object imported as a polymesh in Civil 3d. I need the solid 3d object to do some edit like slice or union and subtract.
The question is "How can I import .3ds into Civil 3d as a solid objects or hoe can i convert polymesh to solid?"

I have a line or a pline segment and i want to start a line from a point laying there and go perpendicular outwards. Is there a way to do it with tracking?
Yes, i saw the command draw line at an angle but i find it a little bit complicated for a simple task like that. I am sure autodesk have a simplest solution about that.
If i am already at the draw line mode and i can easy catch the tracking perpendicular to previous segment but if i want to start from another line and go perpendicular i cannot make the tracking work.

If it would be possible to round the edges of the solid i attached as a .dwg file. I thought it would make sense to use the FILLET command but it didn't seem to work.

I am unable to adjust my Viewport sizes in anyway, (wont allow me to grab handles to adjust size & or move entire view port) after they are changed to the defposits layer, I cant change them back to any other layer because when I try to highlight them, it says "0 objects found". Wont even let me delete them, I don't think they are locked, as I am the creator of this drawing and have done no such thing.

I recently obtained a new laptop with a Solid State Drive and, holy smokes, it's seems at least twice as fast as another laptop with comparable specs like RAM and processor. I used a stopwatch. It was incredible.
Things like opening the program, opening drawings and re-loading Xref's are all way way way faster than without the SSD.
To those of you who have added SSD, are you seeing the same boost? This appears to be an easy way for Civil 3D users to increase speed tremendously, without purchasing a whole new system.

I have created a surface in Civil 3D by adding contours....... Now that I have created the surface I need to Exoprt it to .sat / .stl files. But in order to do this I need a 3D Solid.
How do I convert this service to a 3D solid in order to the the export?
I have tried the thickening option in the 3D Modeling workspace but it doesn't want to accept my surface.

It goes f.e. like this:
I draw a line (no constrains) and I can move it by grabing an end or whole line by click&hold mouse button, great.
But after couple minutes of work with part and sketches I can't grab anything. Even on new created sketches and new lines. Click and drag just open rectangle selection. Oh, between these phases there is a phase when 2nd click&hold works...
When I open/create another part it is normall, but this one I must close and open again.

I am working on some car parks and am using corridors. There are some area's that consist of seperate regions to tie up corner areas and junctions etc.
I am using link codes to create hatch and would like to use non-solid hatch. But the hatch does not appear to line up properly between regions, as shown on the attached image.
