Thank you to everyone that joined my Visualization in Civil 3D webcast on April 1, 2016. For those of you that were not able to join the webcast, here is a link to the recording so that you can watch it.
As I mentioned, this material was all taught from the content that is available in Chapter 8 of the Civil 3D 2016 Grading training guide. I thought I would use this blog to reiterate answers to questions that came into the Q&A and Chat panels.
Q1: Is there a way to import/export material libraries? Or download more styles or templates from online?
A1: Yes. To open a custom library, expand (Manage Libraries) at the bottom of the Materials Browser and select Open Existing Library. Library files are saved with an .ADSKLIB file extension. To import a new material into the drawing, just drag and drop the material into the drawing as I showed in the webcast.
Q2: Is there a section in the study guides that will walk us thru how to use the mapping.
A2: I assume this question has to do with the AutoCAD Map 3D commands. If so, no,the Grading book does not cover any AutoCAD Map 3D commands. However we do have a Map 3D training guide that takes you through many of the commands found in AutoCAD Civil 3D’s Planning and Analysis workspace plus a lot more productivity commands that originate in AutoCAD Map 3D but are available in AutoCAD Civil 3D.
Q3: How could you add materials if your parking lot is created using feature lines?
A3: Create a separate surface for each type of material. Then apply the material to the surface. This means I will create a surface using the Edge of Asphalt feature lines along with any drainage points. Once done, assign it the render material Asphalt. Then I would create a surface using just curb feature lines and assign it a render material of concrete. To ensure you have an overall finished ground surface, create a new surface, then paste into it all the other surfaces starting with the existing ground, then curbs, then asphalt, etc. Keep in mind that if two surfaces share the same location horizontally, the triangles used to set the elevation for the surface are defined by the last paste.
Q4: Why not just use ncopy to import the polyline then assign a finished floor elevation before extruding instead of feature?
A4: Tom Richardson, thank you for pointing this out. I was not aware of the ncopy command until this webcast. That is why I used the featureline command. Now that I know it exists, I will definitely recommend it to people.
Q5: Could you paste those together? The surface that is?
A5: Yes, you can paste the various surfaces together. However, as soon as you do, the entire surface becomes one material. That is I why I suggest using the overall finished ground surface for staking purposes and not visualization purposes.
Q6: I missed that part where you exploded the feature line from the building. After you exploded it, it became a polyline and then you extruded it a certain height right?
A6: Correct, once I had a polyline in my drawing, I used the 3D molding command Extrude to create a solid to represent my building. If you would like to learn more on how to work with solids, check out our AutoCAD 2016 3D Drawing and Modeling training guide.
Q7: Would it help with processing in you turned off the display of the surface triangles?
A7: Are you are asking if it will help the render processing by turning off the surface triangles or the regen process? If so, I don’t think it would hurt especially if your surface is very large. Another option to speed things up is to turn off isolines.
Q8: What specs would your computer need to do the rendering you did today? Like ram and memory?
A8: My computer is running Windows 8, has an Intel® Core™ i7-3720QM CPU @2.6 GHz processor, and 16 GB of RAM. As I said, if you are doing a full render, I highly recommend rendering to the cloud to save your computer from being overloaded. Besides, rendering in the cloud allows you to keep working while the model renders which definitely raises your value to your employer.
Q9: Would you use a mask instead of creating different surfaces to represent different materials?
A9: I found that rather than using the mask tool, I like to create hide boundaries in my overall surface to show other surfaces in its place. Definitely watch the video because I walked through how to do this during the webcast. If you did not catch all of it, buying the book is definitely worth it to see each step broken out.
Again, thank you for attending and for all your positive feedback on this training guide. I love hearing from you on how things are working and how we can make enhancements to the training guides we provide. Feel free to email me at feedback@ASCENTed.com with your comments.
