Civil 3D bug : Modifying sections views offset sampling & minimum elevation

Say i have some cross section views.
There are some cases that i must do the following actions for the Civil 3D section views to match section views made by another design package.
First change the minimum section view elevation.
Next change the section view offsets.
I watch that surface maximum offset values are updated as reported at the section properties.
But graph is not informed and offsets remain !

Sample line group properties, Sections, Sample more sources, Remove, OK and then Add again does not work.
Also closing and reopening the drawing does not work.

Workaround is to swap the actions order. First fix the offsets and next fix the minimum elevation.

For any already existing wrong graphs the only way to show all is to manual or by custom software set for each one cross section view the SectionViewProperties, Elevations, User specified, Maximum value to the value of the Automatic one.

Adding keyword handling to AutoCAD .NET’s GetSelection()

Autocad NET programming : ObjectBrowser documentation error : Selection filters

All the selection methods are documented at the object browser with FilterType as Object. It does not work. FilterType must be declared as Short().
eg SelectionSet.SelectOnScreen(New Short(){0},New Object(){"AECC_PARCEL"})

Civil 3D : Survey : Mass move SurveyPoints

I had a case of a survey that had some points at wrong elevation. The GPS pole height was forgotten to zero elevation.
So i had to change the SurveyPoints elevation. Minus 2m to the elevation of some points.

I unlocked all the SurveyPoints.
Then i selected the desired ones through a SurveyQuery.
Finally i moved them using native autoCAD command Move.
Points were moved. And changed their properties to CoGoPoints! SurveyPoints maintained their original coordinates!

If doing this one by one using either the SurveyPoint editor or by simply dragging, Survey property is kept and coordinates change. Mass move through native autoCAD commands has no effect.

So i had to make the mass changes, export all the points, delete previous import event, CoGoPoints, Survey Points&Figures and finally reimport.

Yet another Civil 3D issue. It is obvious that there might have been lots of manual corrections to the SurveyFigures due to mistakes when surveying. All of them should be done again.

Why such a dummy way of thinking autoDESK ?

Same day found a workaround.
Make a dummy SurveyNetwork
Right click on it, select SurveyCommandWindow
Type MOD ELS BY PtStart PtEnd deltaElev
eg mod els by 35 142 -2
Modifies elevations of point 35 to 142 by -2
At ToolSpace Survey right click SurveyPoints and select Update.
AutomaticUpdate SurveyPoints does not work!!! Has to be manual after this modification.
Next to this a ProcessLinework has to be done also for the figures to update.

AutoCAD/DWG TrueView export DWG, experience, tips, tricks and workarounds

In case of mass export a set of files there are many ways to do it.

1.File/Export
2.File/e-transmit
3.SheetSet manager/e-transmit/archive
4.DWG TrueView

Mass export : 2,3,4
Start on view that DWG was saved last : 1,2,4 (3 always fails. Always starts at Model Space)
Keep XRef insertion point at correct position when insertion is at PaperSpace : 1,4 (2,3 may fail!!!)
Auto find and export all non XRef files DWG is depended from (eg ctb,shx etc) : 1,2,3
Quaranteed export to selected version : NONE
Quaranteed export with AEC objects exploded : NONE

Tip : Before exporting through case 1 to 3 preview Export Report. If it is to fail exporting to selected version it will be mentioned.

Unfortunately, i found no workaround to always create safely an export to the selected version/AEC exploded. I can not understand why autodesk does not fix this problem. It exists through all previous releases.

AutoCAD & Civil 3D : My custom tips, tricks, workarounds and knowledge

Problem : Civil 3D alignment labels do not change next to scale change
Workaround : Select the non responding objects. Set them in another layer. They will adapt scale at once. Set them back to the previous layer.

Problem : autoCAD LT 2011, where is the SheetSet manager
Answer : Sheet set manager was included in the next version. No SSM for this version.

Problem : Plotting to DWF does not use the selected ctb file.
Cases :
1.Works fine when publish through SheetSetManager for Single Sheet printing but fails when trying Multiple Sheet.
2.Does not work at all when in autoCAD LT 2011
Solution for all cases :
Copy the desired ctb file to the default Plot styles folder.
Tools->Options->Plot and Publish->Plot Style Table Settings->Add or Edit Plot Style Tables...
Opens the default Plot Styles folder
