Autodesk Inventor 2020.2 Update

Frame Generator
A new Category section is added to Frame Member Selection in the Insert and Change command to improve searching for a particular Family. When you choose a structural shape Category, the Family list is filtered to show only the available choices.
The Reuse and the Change/Reuse commands now display end treatments and user edits in the preview.
Legacy behavior for reused frame members has been restored. You can now select reused frame members to use as a tool to modify other members.
New controls are added to the frame angle manipulator. You can now do the following to snap to 45 degree increments:
- Shift+drag the manipulator arrow.
- Double-click the manipulator arrow.
Place Component at Origin Enhancement
The Assemble Productivity Place at Component Origin command now supports selecting more than one component to place in a single instance. In the Open dialog box, use the standard windows keyboard shortcuts, CTRL or SHIFT, to multi-select the components you want to place.
Constraint Enhancement: New Setting to Control Axial Constraints
By default, when creating an axial constraint, Inventor tries to predict the best solution for creating the constraint. The new setting, Default to Undirected, allows you to permanently revert to the legacy behavior which was undirected by default.
Tube & Pipe - Derived Route - Workflow Enhancements
- Construction geometry is now ignored when selecting sketch elements to create a derived route.
- Use the new context menu option, Delete, to manually delete an inserted fitting from a derived route.
- 3 new context menu options are added to the Place Fitting and Place from Content Center commands to make it easier to place a fitting on a derived route point: Default Filters, Points filter, and Lines Filter.

Parts

Preview Added to Direct Edit Mini-Toolbar
A preview button is added to the main Direct Edit mini-toolbar for all operations (Move, Size, Scale, Rotate, and Delete).

Features

Return to Feature
When creating and editing sketched features, such as extrusions or revolutions, there is an additional way to return from sketch editing to feature definition, the "Return to Feature" command. It is located on the Sketch tab at the right end of the ribbon, next to the Finish Sketch command. The command text displays the particular feature type being worked on.
Value Edit Controls
When using reference values (dimensions, measurements, etc. accessed from the context menu) in the edit controls in property panels or HUDs (in-canvas heads up controls) the input bar is placed at the end of the value to enable further input such as factoring values and so on.
Hole command
The "Allow Center Point Creation" setting is remembered for the next time the command is used.
Boolean Output Choice
The Boolean output choice is included in the Presets. When you create a feature preset the Boolean choice is included in the preset. The choices preserved are: Join, Cut, or New Solid. The Boolean choice is used in presets for the Extrude, Revolve, Sweep, and Coil commands.
Property Panel - Advanced Settings Menu
This enhancement affects feature creation for both Part and Assembly features.The setting Predict Boolean Operation is added to the Advanced Settings menu for the Extrude command. The default for this setting is checked (ON). The setting overrides the active preset Boolean output choice. Uncheck the option to use the Preset setting.

Sketch

AutoCAD (.dwg) Workflow Enhancement
The workflow to paste copied DWG geometry into a drawing (.idw), part (.ipt), and assembly (.iam) file has been streamlined. Previously, to paste AutoCAD geometry into an Inventor file you were required to enter sketch mode before you could paste DWG geometry. Now, to paste copied DWG geometry:
- In the part, drawing, or assembly file, press CTRL V or select Paste from the context menu.
- Select a sheet, view, or an existing sketch to enter sketch mode. A draggable rectangle displays.
- Left-click to place the copied geometry.

Drawings

General
You can now copy a table and paste it into the same drawing sheet.

Interoperability
DWG File Export Workflow Enhancements
The workflow for exporting and saving a file as an AutoCAD drawing is streamlined as described below:
- The DWG File Save As Options dialog box is renamed to DWG Model File Export Options .
- The DWG File Export Options wizard is renamed to DWG Drawing File Export Options .
- The Export to DWG file menu option:
. Automatically launches DWG Model File Export Options dialog box in a part or in an assembly file.
. Automatically launches DWG Drawing File Export Options wizard in a drawing file.
Note: To bypass the wizard and immediately launch the Save as dialog box, deselect the new check box, Always prompt for Options.
- The Save as type default is changed from Inventor Drawing Files (.dwg) to AutoCAD DWG Files (.dwg) when selecting File Export Export to DWG.

Improved Error Handling Message for Projects

The error handling messages that displays when you try to open a file that is not in the search path of the active project is updated to provide more helpful explanation of how to resolve the issue:

General

Circular Measurement Enhancement
Previously, the measured values of a circular edge displayed in a different order than the measured values of a circular face. All diameter/radius geometry types now display the measured values in a consistent order as follows: Diameter, Radius, Total Loop Length, Area.
Performance Enhancement
Improved Cable and Harness performance when referencing components.

Translator Enhancements

- Support for Creo 6 import is added.
- JT
. Support for JT 10.5, both import (read) and export (write) is added.
. Support for import and export JT files with graphical Product Manufacturing Information (PMI) is added.

Tolerance Analysis

If Tolerance Analysis is not installed, the command in the Environments tab displays a different icon and provides access to the download information.

Known Issues

Install
If Inventor 2020.1, 2020.2 and a standalone language pack were installed one by one after installing the original Inventor 2020 release, then uninstalling 2020.2 will cause subsequent issues. To resolve this, either re-install Inventor 2020.2, or uninstall/re-install the standalone language pack. DEPLOY-4504

Installation Requirements

- Autodesk Inventor 2020 supports Windows 7 SP1 64-bit and Windows 10 64-bit.
- Windows 7 SP1 requires MS KB update (4019990). If not already present on the machine and/or if MS Updates are disabled, this KB update will need to be applied prior to installing Inventor.
- If you are using Windows 7 on a 64-bit system, please verify that you have the Microsoft fix for user mode callback exceptions KB976038. This fix ensures that Autodesk receives the correct data from Inventor error reports.
- If you download the source files to a local folder with a name that contains non-English characters, ensure that the language in Regional Settings is consistent with the language name of the local folder.
- Make sure the Inventor install path does not contain double-byte characters when installing Inventor on a single-byte operating system.
- If the installer prevents you from installing one or more products, pause the cursor over the red "prohibited" circle beside the product name for more information.
- A Warning 1946 dialog may be seen during installation. This is a benign Microsoft warning and can be safely ignored. Simply click OK on the dialog.
- Installation is sometimes slow due to Microsoft security update KB2918614. If so, the installation will require 2-3 hours to complete. For more information, please refer to Microsoft support page.
- Autodesk Vault Basic 2020 is delivered as a separate installer. Customers who use Vault Basic may download both the Basic Client and Basic Server from [Autodesk Account].
- File In Use dialog about Autodesk Analytics Client Service may pop up during product uninstall or reinstall. You can safely continue by clicking Ignore button.
- Use the Autodesk Uninstall Tool to uninstall Inventor. Uninstalling Inventor from the Control Panel may result in the File in Use dialog box prompting you to close Autodesk Analytics Client Service. In this workflow, click Ignore to complete the process. NOTE: We recommend you close all Autodesk products before beginning the uninstall process.

Notes:

* Autodesk Inventor is optimized to take advantage of the SSE2 extended instruction sets supported on Pentium 4, AMD Athlon 64, and AMD Opteron processors. Inventor 2020 will not install on computers that do not support SSE2. Several utilities are available on the Internet that report CPUID including supported instructions sets.
** Autodesk recommends settings which allow Microsoft Windows to manage virtual memory as needed. There should always be at least twice as much free hard disk space as system memory (RAM).
