We are now MicroCAD Training & Consulting



Thanks to you Delta Engineering Systems has been an Autodesk Reseller for thirty-two years. We have recently been acquired by MicroCAD Training and Consulting, an Autodesk Platinum Reseller, headquartered in Boston, MA,  and with offices around the country. Our new website is


I will be staying on with the company, in order to transition your subscription accounts to MicroCAD and to continue providing technical support and training services.

Many of you will gain additional value from this acquisition. MicroCAD is very strong in support, training, consulting and customizing Revit software. My personal experience in Civil Infrastructure will enhance MicroCAD’s overall offering for multi-discipline firms.


As of August 13 2021, our Autodesk sales are being conducted under MicroCAD with all quotes, renewals and payments through them. We highly enjoy working with you and greatly appreciate your loyalty. 


Please feel free to email or call me with questions.

New training course

Use the tools in AEC Industry Collection to streamline your civil workflow

Land development project efficiency increases through the use of AutoCAD Civil 3D and InfraWorks 360 as partner applications

This course guides you through a typical workflow for a land development project, using both Civil 3D and InfraWorks, with the goals of reducing early-project design costs and improving communication throughout project lifetime. This course is designed for Civil 3D veterans, experienced users who do not need instruction in the basics of that software, but are newer to InfraWorks and the efficiencies it provides. Click here for more details...


Still not convinced that InfraWorks will shorten your civil project-design cycle? Read this report commissioned by Autodesk.

Many new features beg your attention. Read about it on Tim's Civil 3D blog : AutoCAD 2018 New Features and AutoCAD Civil 3D 2018 New Features.


Introducing Autodesk Industry Collections

Autodesk has made significant changes to their software offerings. Various suites, such as Infrastructure Design Suite and Building Design Suite have been discontinued and replaced by the AEC Industry Collection. This collection includes AutoCAD Civil 3D, Revit, InfraWorks 360 and AutoCAD as well as other popular titles like Raster Design, AutoCAD Map 3D and Vehicle Tracking. Contact Delta Engineering Systems, or 530.221.2994 for more information.

Important technical upgrade for Civil 3D 

Autodesk has released the Performance Enhancement Tool to address reports of bloated drawings and excruciatingly long AutoCAD Civil 3D drawing load and save times. This problem affects drawings using any version 2013 through 2017. As is Autodesk policy, they only support three versions prior to the current, so the fix described below will cover 2014 through 2017. If you are using 2013, you might consider – should seriously consider – upgrading to a more-recent version. Please see our Support page for details.
