On starting a new job the default text size was being picked up from old CDS2 installation. Now fixed.
Saving and loading of default screen/plotting parameters was going back to CDS2 directory.
New job was setting the display point range values incorrectly. Now defaults to not setting any range so whole job is shown.

Monday, September 28, 2020

Ezigrade 4.1.33

A few minor fixes and improvements
  • when importing a landxml; Ezigrade was not automatically creating surfaces and contours
  • if fields were too close together we could be losing section nodes - hence sections not correct
  • deleting a section could leave extra points that were added along that section
  • when clicking on reset for grid - the grid was not automatically getting displayed. You needed to redraw the screen

Ezigrade 4.1.31

Some triangle based grading sections would not finish. There was a numerical issue in the linear programming.

Fixed a bug when importing LandXML. 

Friday, July 24, 2020

Ezigrade 4.1.30

Bug fix in linear programming. Under certain circumstances  the variable grading could lead to "infeasible solution" even though a solution is possible. Variable grading with constraints on one axis only has been speeded up.

Ezicad 4.1.29

When using the triangle based grading we have improved the smoothing option. It now knows how to fix up the smoothed surface around section links. When running the grading we have the following dialog presented.
Tick on the "smoothing between sections" option and add in a value distance to use. Make it big enough to include any imperfections around the link.

Ezigrade 4.1.28

Possible error when creating a TMX specific Trimble .gps file; when we have design heights only. The file does appear to work on the TMX display but leads to complications when we are displaying file in our on-line viewer.

Web Site Issues

We are presently rebuilding our web site after changing our hosting provider. For some reason thinks it is acceptable to simply delete all our files without any warning or explanation. After innumerable phone queue's we find that our last couple of payments were not processed. Rather than ask us for payment they simply delete your site. Why don't they hijack the site and put up a payment page. Is this the way to treat a 20 year client!

Ezigrade 4.1.27

Have changed the waterflow display. Changed name to Tributary and now display the water-flow streams. You have option of entering number of grid edges and a display threshold. If you enter 200 for grid you have 40000 grids and the threshold is how many cells flow into this cell. We also display some black cells that are grid cells where water doesn't flow from. ie a pond. Here is an example display:

Ezigrade 4.1.26

Under Contour -> Surface Parameters ; the remove skinny triangles along edge of job could remove interior triangles. This has been fixed.

Import Trimble FieldLevel now supports section lines.

Monday, April 6, 2020

Ezigrade 4.1.24

Have improved the File -> Print Preview and the File -> Print options.
To print out what you see on the screen:
  1. Under the File menu display the "params" dialog and fill in scale, margins etc
  2. Bring up File -> Plot Window and move the window around the screen to cover the portion to print
  3. File -> preview displays a preview
  4. Do File -> Print
Remember however that there is still the option under Export to export a bmp or jpeg etc if you prefer.

Ezigrade 4.1.23

Have added in a new import option. This is for importing from FL2 box which now seems to support an xml format.
Look under Imports -> Trimble XML
This is a different format XML from LandXML

Ezigrade 4.1.22

If you type in a grade constraint /smoothing value etc then that constraint is automatically enabled. ie the button is changed from red to green for you. New users were getting lost as they would change the value but not realize they also needed to enable the constraint.

If you now click into a constraint item the existing text is now highlighted. Typing in a new value automatically deletes the existing value. This makes it easier for tablet users.

Ezigrade 4.1.21

We now have 9 color ranges when drawing surface colors. For cut and fill colors this gives us a band in the middle and an equal number of bands for both cut and fill.

We have also added in a "from" column. The dialog always synchronizes the from column with the previous to column.


We now have 9 different colors when doing surface colors. This allows us when viewing cut/fill to have a middle range and 4 ranges above and below this range.

Ezigrade 4.1.20

The report option wasn't working if there were any drains not merged. This has now been fixed. Large jobs were failing when exporting to Topcon Civil. This has been improved and a further update will come out later.
