I have created a building pad on my site and need to extract fill quantity. I set the elevations on my building and created a 5:1 grading object. to the existing ground.Autodesk Instructions are, for the actual building footprint, that I need to create a grading object at 1:1. for the area covered by the actual concrete pad. Would someone who has this grading criteria please send me a screen shot of the style settings. because the area is flat it is impossible to determine if the floor area has been built. When I run sections and create volume reports the only fill quantity is from the grading objects that slope out from the pad. I must be overlooking a setting in the style for 1:1. Thanks
Solved! Go to Solution.
Are you sure about the directions from Autodesk? Typically you would use a Grading Infill object to create a design surface within the closed area of a grading pad.
My building pad is 30x200. we are building a pad for the foundation with 5:1 slopes to natural ground. When I create the 5:1 slideslopes and create sections, so that I can extract quantities, the volume report just has the sideslope quantity not the proposed fill directly under the actual concrete. In researching Autodesk instructions you are to create a grading criteria that is 1:1 and apply it to this area so that it will be included in calculations. Autodesk is not clear as to how to handle the criteria. When you create 5:1 you instruct the criteria to extend to the existing ground.Tis is not applicable to the 1:1 since yu are looking for a quantity under the entire footprint of the building I do not think I have settings properly created in my 1:1 criteria and would love a screen shot of the grading criteria definition for 1:1
Can you post a link to these instructions? It sounds dubious.
A 1:1 slope is not horizontal, it is a steep slope! That's 45 degrees!
Why don't you just use your feature line to build a TIN surface that you can then use for volume calculations?
Credit where credit is due! Give kudos or accept as solution whenever you can.
LOL. Brain dead yesterday. I have to compute quantities about once a year. You are absolutely correct on the one to one. I came in this morning and used the tutorials to figure out in-fill. I obviously misunderstood the directions. When all else fails read the directions. Thanks for your help. We have quantities!!! Next time we are slow I am going to redo the tutorials and see if I cant retain the info for next year.
1. Are you using the "Create Infill" command in the Grading Object? This would account for no earthwork beneath your pad.
2. It appears that I agree with the others here, the the 5:1 slopes is all you need (no 1:1).
