Grading Updating Automatically

When I move a vertex on my feature line the corresponding grading updates automatically. I would like to pause the rebuilding of my grading until I have made all my edits to the feature line. It becomes very time consuming to wait for the grading to update every time I move one vertex.

There must be a setting similar to the rebuild of surfaces where I can specify an automatic rebuild or rebuilt on command. This might be buried in the multitude of setting windows but I cannot find it anywhere. Thanks, any help is appreciated.

Thanks but I actually want my grading not to update automatically; essentially have that rebuild option but for my grading group.

Here's a little more background, I have two feature lines and created a grading group based on them. Now I want to edit several vertices along the feature line to adjust the grading. However, each time I move one vertex my grading updates and that takes a minute. I have over a hundred vertices on each feature line which I will be moving around (so now that minute in between vertex edits really adds up). I anticipate several rounds of edits to my feature lines so I'm looking for a way to cut down the time it takes.

Hopefully that makes sense...I work at an engineering firm and every person who has done similar work has run into the same problem. The only work around seems to be deleting the grading group, make my edits, then recreate. But with such an iterative project, this doesn’t save to much time. Thanks.

The grading will still rebuild in this case. The surface usually takes very
little time to rebuild. The OP I'm sure is wanting to halt the grading
object rebuild and not the surface. I don't think this can be done however.

Yup thats what I want. It seems that option should exist but maybe not...

It seems to me you would not want to have grading updates disabled. Think of
what would happen if you started moving vertices on a baseline around while
the associated gradings stayed in place. Aside from being disorienting, it
could also be distastrous when you finally tell C3D to update everything.
There would be crossing breaklines and gradings everywhere which would
likely cause a crash. If you wanted to save your work up to the point of
updating, you would probably not be able to recover your drawing as it would
try to process the grading and crash every time you open it.

It seems to me that for the forseeable future we are going to have to live
with things as they are.

I agree with Neilw.... but shouldn't there be a way to change the style of a feature line (say from no display to some standard style) without completely rebuilding the grading? I'm not making any changes to the feature line itself.... I just want to turn it off and on without re-grading the entire site... (This wouldn't be an issue, except it takes quite a bit to update...)

Nail on the head (hit the).

Delete the group then rebuild is the preferred method (currently). Don't forget you can use a corridor for working instead where you anticipate lots of iterations.

I agree the ability to Turn off automatic updates would be very beneficial especially when making minor edits although Neil has a good point. Perhaps we need an update Y/N dialogue option.

It is 2021 and this is still not available. I am inserting vertices to a feature line that is the base for a grading an I have to wait minutes between each point. Have been doing this for half an hour and managed to insert 2 points because you have to wait for the rebuild...

We need the gradings to update when we make changes. The problem is the performance of the software is making it take too long. Here it is 11 years later and we are still struggling with this horrible performance while we instead get new ways to make pretty presentations with Infraworks.

@Neilw_05 My suspicion is that the grading objects are built on ancient code and it wouldn’t look good to the shareholders if resources were diverted to fixing this. I am led to believe that performance issues are the current hot topic and they are looking at certain things in a bid to improve things. 

 

@peterfarkas What are the specs of the machine you are using?

I absolutely believe the technology is fundamentally deficient and thus these issues cannot be fixed. That is why there have been no significant improvements in the grading tool issues since the beginning. The only solution is a new product.

I have a good machine. But I work a lot with earthworks that require complex grading objects that sometimes build on feature lines derived from each other. Also working with point clouds is becoming more of a standard so even when I simplify the surface especially for grading purposes has a huge amount of triangles still, so a lot of computation.

 

Otherwise I work on a good machine. But still things sometimes painfully slow.

Unless something has changed recently, having a Xeon with all those processors yields very little benefit.  Basically Civil 3D only uses one.

Hello,

 

I have found a workaround:

 

1. create a simplified surface from a square with the average elevation of the target surface, this will be our auxiliar surface: "AUX-AVRG ELEV".

2. replace this auxiliar surface as the new target in the grading (right click, grading editor).

3. move the feature line as you please, it should be a lot faster now.

4. change the target back to regenerate the actual grading (right click, grading editor).

 

I hope this was helpful

Hi

 

That is not a bad idea. Might try it next.

 

However since then I stopped using pointcloud surfaces. Too slow and result in crazy grading outlines (too much detail). When I need to create gradings, I decide on some precision based on what sort of area and/or project we are talking about and extract contour lines from the point cloud to create a grading target surface from those extracted contours. (Most areas I use 10cm contours which is well enough precision in most cases.) This way the gradings go real quick and the precision also doesnt suffer.

I use point cloud surfaces BUT I use Surface Simplication > Edge Contraction > 70-80% reduction and this grossly reduces the surface size while keeping the required DTM accuracy and all remains dynamic.
