  Importing CAD Data
Posted by: KevinD - 08-13-2019, 07:27 PM - Replies (1)

I understand how to import CAD data. The problem I have, however, is that I'm trying to import CAD data into an existing project that was already established using points from a pdf.

What has happened is the overall site has been surveyed in 2 phases. The information for Phase 1 was issued as a PDF and I've manually inserted all of the elevation points and boundaries. It's important to note that these features have 'default x and y co-ordinates because the 'actual' x and y co-ordinates are not available from the pdf.

I now want to import the Phase 2 points and boundaries, but as these features come from a dwf file they are imported with 'actual' x and y co-ordinates as part of their geometry that do not match the 'default' co-ordinates from the PDF.

I've watched the video and read the help files but I cannot find any help that will allow me to adjust a base x and y co-ordinate of the features I'm trying to import from the dwf drawings to match the points established from the pdf.

Can this be done and if so how?

Most forums I meander have a "say hello" section for new members.

I signed up for a Kubla license a week or so ago and since I am now 'the new guy', thought it best to say hello.

Perhaps also find people in my area who use Kubla.....

I am from South Africa and now live in Perth, Australia.
Use to draw pretty houses for a living, then moved countries and did earthwork estimation for a couple of years. Now have a small metal fabrication business and again do earthwork estimation on the side after hours.

G'day mates

  Road Box Out - How to?
Posted by: Bushman - 08-05-2019, 09:20 AM - Replies (1)

Good afternoon.

Would anyone be able to assist with how to box out the proposed road pavements please?

I was given a natural & design TIN file and a PDF showing the face of kerbs of the roads.

I can trace the face of kerbs using the 'strip' function, but how do I offset this line 600mm to the outside of the road which represents the extent of the base and subbase layers below?

I will try and upload a section sketch.

I cant seem to post a photo from my phone. I will keep trying.

  Separating fill areas
Posted by: Michsitework - 07-21-2019, 11:15 PM - Replies (1)

I am new to the program, just working through my first take off. I am wondering how to go about figuring out a cut/ fill volume for only greenspace. The issue is the on site soil is unsuitable to be used for any areas other than greenspace. I would like to break down the greenspace balancing to use these soils to fill where needed. Basically, I would need to calculate the difference for all the greenspace from the existing elevations to proposed, I'm just not sure how best to do it.

Good evening guys

Please would you see if you can help.....?

It has been 5 years since I did any earthworks takeoffs. Previously used 12D (Australian product) and now hoping to get back into it via Kubla.

I have an opportunity to start a 'side business doing takeoffs but first have to prove to the client I am proficient.

The estimator sent me a 'dummy project' and it has me stumped.

The files sent are in DWG/DXF and I am not getting the info I need.

Looking at the help files it seems you guys are using external CAD software to weed the file of unwanted info and then importing it into Kubla.

This is a very simple job but I am struggling with weeding out the info and getting it imported into Kubla.

Please..... please...... help.

These are the files I was given.
What 3rd party CAD software are you guys using to extract 'existing' and 'design'?


The CAD file has the usual 2D info and the 3D info. Viewing it in 3D you can see the info with '0' Z value as well as the info which has 'Z' values. The info with 'Z' values is shown with existing and design. But I have no idea how to seperate the two in Kubla.

Kubla gives options for 'break lines' 'contours' & 'boundaries' but not for the point vertices (existing spot levels).

I know am new to Kubla and the answer is probably right in front of me........... apologies for that....

  Accuracy of Grid Method for Cut\Fill Analysis
Posted by: Ted Woods - 07-05-2019, 01:35 PM - No Replies

We have published a new blog post : 


For those who are not using software to estimate earthworks volumes, the Grid Method is by far the most popular of the manual methods.  We are sometimes asked about the accuracy of this method.  It’s not easy to give a short answer to this question, because it varies greatly based on a number of factors.  In post we try to provide an answer, and give some practical guidance to those that are using this method to estimate earthworks quantities.

  New Kubla Cubed blog post on error messages

We have published a new blog post to help users with projects that aren't calculating.

Error Messages in Kubla Cubed

All software will give errors messages from time to time, and Kubla Cubed is no different.  In this post we discuss the ‘Calculation Error’ message which can sometimes occur when working on complex projects in Kubla Cubed.  We also discuss the calculation steps used by the software, and some of the new error reporting features that were introduced to the software in Version 5.7, released in July 2019.

I am new to Kubla.
Wondering why my cut volume is showing as a 13 digit number- the actual volume is 8,984m3. see attached screen shot.
When I use the measure tool the scale is correct on the drawing.

  Break Lines Again
Posted by: KevinD - 05-05-2019, 03:51 PM - Replies (1)

Hi all,

I'm setting up the existing features of a site I'm working on (Outline. Contours, points and breaks). I note that it appears to me that the option to create break lines "at crossings" has been taken out of the program and now the only options are to add them from a file or manually. The manual option is straightforward enough, although I note that if you don't add more than 2 points the triangulation will ignore them.

My problem with the use of breaks is this:

On my large site plan I have a 4 existing large buildings which are all complete to at least their ground floor level and I know what those ground floor levels are (FFL ranges from 9.45 to 11.80), plus a lot of other 'physical' features (e.g. transformer vaults and concrete pads) from the previous contract.

I have lots of contours and elevation points to work with (in fact the site is relatively flat, having been partially leveled under an earlier contract). However, what I don't know (for any of the buildings or other features) is the actual ground level at the point where ground meets the building/feature. All the surveyor has given me is the FFL or the level on top of the feature (and some of these features are raised well above GL).

And so my questions are:

  1. when creating a line break do I use the GL at the point where the ground meets the feature or the level of the 'feature' itself (e.g. the FFL, the top of the transformer vault, top of kerb etc)?
  2. if I have to use the ground level when creating a break, but I don't know what the GL is at that point (even though I know the level of the 'feature'); because the software will not interpolate this level for me, what would you recommend I do?
  3. is there a case for saying I have to use two breaks? One to break based on the GL and the other for the 'feature'? - take for example the case of a raised roundabout, around which I placed a break based upon the GL at the base of the kerb. I also have one point level that defines the level of the ground for the roundabout itself. Do I just add that level to my model and let the software work things out or should I be adding a second break around the feature based upon this level?


  [HELP] 2019 Crashing at outline creation
Posted by: conradccb - 04-30-2019, 12:42 AM - Replies (2)

Hi all,
My Kubla 2019 keeps crashing when trying to apply creation of a Manual (but auto calculated) outline of Design Contours.
The design contour has ~4000
It has an Existing surface uploaded via DXF. 
This is the point before it closes. Once I click OK, the program just disappears.
Note it also crashes if I manually draw a smaller area (jsut around the lower basin).
Any ideas?
