Understanding the new Trim and Extend commands in AutoCAD 2021

Autodesk AutoCAD 2021 brings new functionality with both the Trim and Extend commands.

As opposed to previous versions, you no longer have to select a cutting object to trim to, saving you a few steps. This can become a problem, however, in crowded drawings as I will demonstrate in the linked video below. There are options to alleviate these issues and restore previous functionality either temporarily or permanently.

 

AutoCAD 2017-2019 Combo Security Hotfix

Autodesk has releasee a series of security Hotfixes today to AutoCAD 2017-2019, and vertical products, to remediate multiple vulnerabilities discovered through testing and research by software security experts.  These critical updates should be applied by all customers.

These updates will be listed in the Autodesk Desktop App for all products installed on your computer by year of product. The Hotfix installer will automatically install all previously released Updates and service packs on your computer.

AutoCAD and AutoCAD LT 2020.1 Updates Released

The AutoCAD 2020.1 and AutoCAD LT 2020.1 Updates have been released and are available for download and installation via the Autodesk Desktop App or your Autodesk Account portal.

This update contains new features and bug fixes to AutoCAD and AutoCAD LT 2020 including the following:

 

Using Surface Snapshots in Civil 3D

At one time or another you may have opened a Civil 3D drawing sent to you and noticed, while viewing details of a surface in the Prospector tab of the Toolspace, what looks like a little camera icon next to the Definition section.  What does that little icon mean?

That icon stands for a surface snapshot, and in this article, I hope to help explain what a surface snapshot is and how it is used.

According to the Autodesk Civil 3D Help file:

AutoCAD 2020 Block Performance Hotfix

With the latest version of AutoCAD 2020, a new Block pallette gives new functionality in organizing, loading and placing blocks in your drawing. 

However, when opening drawings containing a large number of blocks, there is a definite slowdown while the drawing is organized to catalog these new blocks. To alleviate some of the delays, Autodesk has issued a Hotfix for AutoCAD 2020.

Creating a subassembly from a polyline in Autodesk Civil 3D

Corridor modeling is a powerful tool for creating simple or complex road and other linear 3D design models.  One key to its versatility is the use of custom subassembly parts to model non-standard components of the corridor.

In the video below, Seiler Design Solutions will show you how to create a simple corridor subassembly from a polyline and add codes to the various points, links and shapes that get created.

Civil 3D Surface Watershed Analysis

In video below, Seiler Design Solutions will show you how to display your Civil 3D surface as a Watershed Analysis style. The method of setting up your style will be described, along with some of the other options involved.

Once the Watersheds have been displayed, you will be shown how they can be used in conjunction with the Flow Path tool and the creation of Catchment areas that can be exported to Autodesk Storm and Sanitary Analysis for further use in drainage design.

Create a Civil 3D Surface from 2D GIS Contour Data

You have GIS contour data of a site in .SHP file format.  You import the data into your design only to find out it is in 2D.  How do you turn this 2D data into 3D data easily to create a Civil 3D surface

In the linked video, I will use Map 3D tools from within Civil 3d and show you how to import 2D contour data from a shapefile into a drawing, query the data to another drawing to elevate the imported polylines and finally create a Civil 3D surfrace from this data.
