Our digital code signing certificate has expired. Until we get a new one you will have a screen as follows if you try to install CDS or Ezigrade.

Simply click on "More Info" and you will see the option to "Run Anyway".

If someone wants to ask Microsoft why it is impossible to install an application with an expired certicate, you get large red screen. I would love to know the answer. Rebuild it without any certificate at all then you get screen above, which most people are used to anyway! 

Ezigrade 4.16

Bug in Esri Shape file import. Problem was when data was a polygonZ and didn't include optional M measures. Now works in this case.

Ezigrade 4.15

There were problems getting a valid solution for constrained grade and plane solutions joined together with hinge/hinge's.

Ezigrade 4.14

Introduced a problem with "File" -> "Save As". Field sections where being doubled up.

Ezigrade 4.13

Have added in and improved functions to create contour banks. Contour banks are added in for erosion control. It creates smaller runs for the water; thus reducing velocity.

We can now specify an alignment and hang contour banks left and right at appropriate distances or heights. These contour banks are created as drains/banks so existing drain functions can be used to edit and tweak the final design.

Access for the new banks menu item.

CDS 2.8.0.67

Natural volumes were not working if the road numbers were not in order. For example road 1 and 2 would give volumes but roads 1 and 14 failed. Now fixed.

Ezigrade4.12

Added in some point viewing and manipulation functions to Ezigrade.

Find them under Contour -> Edit Model and you will see the point table and points by polygon. Picture below shows point table docked to the left. You can highlight a line and delete a point. You can manually change height, design height or code and it is updated within the Ezigrade model.

You can now draw a polygon around a series of points and then delete them from the model.
