I was teaching a standard Civil 3D class this past week when one of the students wanted to know how to create a slope map with hatches rather than just colors. Their client requests slope maps with different hatch patterns representing different slopes. Apparently there are many users who need this same concept because the client in question happens to be a major city here in Texas and they require this from all their engineers.
The wheels began to turn and I came up with this method.
Beginning with the surface you are need of the slope analysis:
Select the surface, right-click and assign it a surface style that uses slope banding. Here I’m using the standard “out-of-the-box” Slope Banding (2D) style:
The problem is that this style generates AutoCAD solids to perform the slope analysis. We need hatches. So we need to modify the style:
In the surface style dialog box, navigate to the analysis tab Navigate to the Analysis tab, and change the display type from 2D solid to hatch solid:
Back in the surface properties dialog box > Analysis tab. . .change your analysis type to Slopes, edit the number of ranges you need, and push the down arrow to run the analysis. You will then see your slope ranges. You can double click in the minimum and maximum slope ranges to adjust your slope values:
You will see a surface which looks like a standard slope map:
The issue now is that you have your slope map but you don’t have any control over the hatches or hatch patterns. To rectify this we must now extract the hatch data so that we can modify it. FYI – this hatch data will no longer be attached dynamically to your surface. So if you need to update the slope map you will have to go through this process all over again.
To extract the hatch data, select your surface and in the contextual ribbon you’ll see the option to extract objects:
In the “Extract Object from Surface” dialog box verify that slopes is checked on and click ok:
Do not click anything else. You’re surface is still selected. So now right-click > surface properties > information tab and set your surface to a “No Display” style:
You will be left with a bunch of solid hatches on your screen. Select one and view it’s properties. In this example I have a bunch of solid hatch patterns that are color 60:
Now I will select all the hatches in my drawing that are color 60 to modify them all at once. Use the QSELECT command and set it to look at the entire drawing and find any hatch that has a color equal to 60:
You will see that all the hatches in your drawing that are color 60 are now selected. Your contextual ribbon should now display the hatch editor. Change the hatch style to your desired style, hatch scale, and, if need be, another color. Here I’ve changed the pattern from solid to ANSI37, adjusted the scale to 100 and left the color as 60:
You should then see your hatches appear with the settings you selected:
Repeat the QSELECT command for your the other colors.
Most, if not all of the Autodesk 2015 products are now shipping and are available for download, with the Suites soon to follow.
As always, we strongly recommend that you, your CAD Manager, BIM Manager, or whoever handles this sort of thing download and install the new software on a non-production machine first to explore the new features, before rolling it out to your entire office. Don’t forget to disable your anti-virus software before installing, and when you download, do not use the “Install Now” option. Use the “Download Now” (Download Manager) option ideally, or failing that, use the “Browser Download” option.
I’ve had many people in the past ask about how to turn off those pesky corridor frequency lines. Most people just want to know what layer they’re on so they can turn it off:
Recently I received a call from a client who generates alignments in Civil 3D and had a desire to hide the alignment through the geometry points as so:
I get a lot of phone calls from people who are interested in drawing objects in 3D so that they can use them in their Civil 3D models. I ask what kind of objects that they in need of. The answers are usually of signs, trees, and other items of the sort.
We’ve had a few calls from users who are having issues with their Civil 3D 2012 licesnses once they’ve installed their Infrastructure Design Suite (Standard, Premium, or Ultimate).
If you have installed any of the latest Infrastructure Design Suites (2013 or 2014) and you’d still like to have Civil 3D 2012 running alongside you will need to install the Autodesk Infrastructure Design Suite Network License Hotfix on each user’s computer.
The reason for this is because you are now running a design suite license and the design suites did not exist in 2012.
We’ve finally made it available on YouTube. . .the infamous video that explains one procedure on how to import GIS data into Civil 3D. Yes, you read that correctly. . .”one procedure.” There are a few others. This is a method that I’ve been using for years simply because it’s simple. The other methods aren’t hard, but you need to understand a little bit about Map 3D before you can use them.
Remember, I’m not a GIS guru nor do I know where all the GIS websites reside.
The data that I’m using here is data that I’m familiar with and was found freely over the web, but most GIS data could be imported and act in a similar manner. I hope you find it informative.
Apparently service pack 1.0 for Civil 3D 2014 fixes most issues but it creates one more. At this time there is an open discussion of this on the Autodesk Discussion Forum. If you use corridor sections to calculate material volumes then this is important to you:
Civil 3D 2014 SP 1.0 Bug
Many of you who read my previous blog, The Dirt Modelers, have been asking if those infamous corridor videos will be making their way to this blog. Not wanting to disappoint, they’ve been converted to YouTube format. I hope you enjoy them. Continue reading
If your Civil 3D software crashes randomly during some of the most basic functions such as drawing a line or copying and pasting then Autodesk has provided a checklist of possibilities and their potential solutions in this Program Crashes Using Random Commands technical document.
PS – I know this document was written for Civil 3D, but it very well could be solutions for other AutoCAD-based software.
