Need Help for Parking Lot

[Anonymous]

Hello everyone . 

i should creat a parking lots like picture . any suggestion or toturial for that ?? and  i have 3-4 elev levels on my lots and i really dont know how to handle that !

You can create surfaces from the main elevation areas (as you have done), then further define them to accommodate drainage flow as desired (crowns, gutters, etc.,), then create featurelines for your curbs from polylines & project them to your simple surfaces for gutters, top of curb, etc., and go from there.

Here are a pair of Bartels videos discussing using relative featurelines to create a parking lot:

Hope that give you a start! Good luck!

Hello And tnx for answer .

i saw those videos before . actually am using Civil2016 right now . isnt there any simple way to fix my problem ? 

im not a pro civil3d user.

When you say fix your problem I sense your anxiety. Approaching the  task with civil3d early on is rife with how do I do that and you get stuck. The reality is you have to ask yourself how would I do this on paper. once that is clear in your  mind you can do the same on the computer.

As a beginner you probably should get you feet wet with feature lines and those editing tools.  Make the parking lot one continuous FL.

Based on your existing conditions you probably have an idea which direction you want the pads to grade - draw in the direction arrows on your sketch.  you may need to add more FL to make crowns or Valley gutters down the middle of your interlocks. Now use the editing tools to make that happen.

You Got this

I agree with Joe - best to just dive in to featurelines & get familiar with creating/editing them. If that still seems too daunting because you just need to knock this out, you can use always use 2Dpolylines with elevation & 3DPolys if you're more comfortable with them.

A lot of us here have been right where you are, so don't hesitate to reach out for help!

Good luck!

Nice touch 👍

Hi @Anonymous ,

Thanks for posting and welcome to the forum. 

I echo @Joe-Bouza 's sentiment. 

Thanks @JRitner for sharing the 2 videos from Jeff Bartels, these are great resources to help you understand and get started with. 

Here's another resource with dataset to help you get started, but you will need to have version 2018 and newer...

Be More Efficient When Grading Parking Lots in Civil 3D course

[Neilw_05]

An approach I use is to create featurelines for the edge of pavement for the parking lot an then drape the vertices on the existing ground. This gives you a starting point for the grading. Add the featurelines to a surface as breaklines and add slope labels to give you a feel for what needs to be done to make the parking lot slopes acceptable. You will then need to consider proposed building elevations, connections to existing roads etc. as constraints for your grading and work your way out from those.

Grading is an art that you learn from experience. There are many techniques and tools at your disposal but you need to know how they work and their limitations. There is a steep learning curve if you have to figure it out on your own. Unfortunately the user group is not able to provide adequate help for this. You really need someone who can walk you through your project step by step. There are lots of videos on YouTube and Autodesk University that cover these topics, but again it takes a lot of time to find them and view them.

There really are no shortcuts to getting your finished model unless you have someone to teach you step by step. Otherwise you will have to work your way through the process and learn as you go.

My approach has been to take my office projects home and work out the techniques by trial and error and doing research on my own time. Then when you go back to the office you are better equiped to move forward and be able to bill your time.

Probably somewhat similar to what Neil is doing, I like to run alignments around the back of curb in a parking lot.  Have the assembly just be a curb on one side and a shoulder, etc plus daylight on the other side.  If the project wants catch basins in the driving lanes, draw feature lines along the "swales" in the pavement.  For quick contours, let these edges connect with your triangles and you have a surface. (edge of curb to feature lines.)
