Before you go, make sure you understand how to manipulate the X3D images under X3DOM with mouse and keyboard.
In the order of 50 core parameters of the aircraft are used to calculate more than 3500 input parameters required for the OpenVSP file of type *.vsp to sketch a passenger aircraft. For each of the core parameters a proposed value is given in the user interface and automatically applied as long as the user does not specify his/her own value. This is a fundamental principle of the program: The user is never left alone with an empty data input field. White input fields (on the left of the screen) are always filled with a proposed value (calculated on the right of the screen). See Screen Shot for details. The calculation is based on aircraft design expert knowledge: standard aircraft design equations, aircraft design statistical equations, geometric considerations, and common sense. Documentation of this is included in the download. Experienced users of OpenVSP-Connect have the possibility to shape the expert proposal by setting related factors or to supply another value all together. Many cells have attached comments (note the red triangle in the corner of the cell) to give further guidance.
Using all default values, the program works in "automatic mode". The calculation is then based on just two input values cruise Mach number and number of passengers. Other input parameters that can be considered a fundamental design selection are: engine type, number of engines, cowling cover percentage, number of blades, wing type (trapezoidal or double-trapezoidal), wing aspect ratio, vertical position of wing (in % with respect to the fuselage height), vertical position of the horizontal tail (in % with respect to the vertical tail height), dorsal fin (yes/no). These parameters should be changed by the novice user to get some feel for aircraft design and to realize first design ideas. The aircraft automatically drawn as such in OpenVSP may not satisfy in all aspects. For this reason, the user should go back to OpenVSP-Connect to change input parameters in an iterative manner until a satisfactory, good looking aircaft results in the OpenVSP 3D visualization.
Subsequently, the user may want to continue with further refinements of the model in OpenVSP. Do you want to add winglets? Do you want to change the shape of the fuselage? All such things - and much more - can be done in OpenVSP Version 2.
OpenVSP Version 2 may also be used to analyse the aircraft model. The tools are found under the "Geom" menue:
Unfortunately, a Version 2 model experiences some conversion losses, when imported into OpenVSP Version 3. Luckily, fuselage, wing, and tail will survive the conversion. Lost are the engines, propellers, and (indication of) the landing gear. The pylon (on jet aircraft) survices, but should probably be deleted. What you are left with is exactly what you really need - a simple geometry suitable to start the extended analysis features of OpenVSP Version 3 inlcuding CFD with VSPAERO. If you do not need these extended analysis features from Version 3, just stay with Version 2.
As the lecture progresses, other tools are introduced. It starts with Chapter 5: Preliminary Sizing, where the Preliminary Sizing Tool: PreSTo-Classic is introduced. This module and others from the PreSTo Program Suite will lead to an ever more refined aircraft definition. At the end of each step is the necessity to visualize the resulting aircraft with OpenVSP-Connect! Now, the nature of aircraft design is to work with various tools forming a tool chain, as explained also at SAS - Simple Aircraft Sizing. This goes on to sophisticated aircraft design tools at PhD level. Have a look at OPerA - Optimization in Preliminary Aircraft Design. You may also look at the research project Airport2030, where the "Optimization of Propeller Aircraft" led to a PhD. We understand: The need to visualize aircraft design results (with or without OpenVSP-Connect) is a necessity at every step.

OpenVSP-Connect runs on OpenVSP 2.2.4 for Win32! If you want to work with OpenVSP-Connect you MUST work with this older OpenVSP version. OpenVSP 2.2.4 for Win32 is provided as part of the download below! If you work with a Mac, download OpenVSP 2.2.4 for Mac OS (see below). Excel (Microsoft Office) is also available for Mac. I have not tested OpenVSP-Connect in this combination on a Mac. So, please report your experience. OpenVSP Version 2 is not available for Linux/Ubuntu. Sorry, I have no solution here.
Historic note: OpenVSP-Connect was developed and tested on release 2.2.4. It should and seems to run also on the two newer releases 2.2.5 and 2.3.0. Reported have been bug fixes towards 2.2.5 and bug fixes towards 2.3.0, mostly related to details of CFD meshing. Release 2.3.0 was the last (and ultimate) Version 2 release. OpenVSP-Connect is incompatible with releases starting from 2.9.0 because 2.9.X is an alpha and beta series leading to Version 3..
Everything you need is in one ZIP-file, which includes also OpenVSP 2.2.4 for Win32.

An official VSP User Manual was written and Video Tutorials were produced just before VSP was released as an open source. Text and videos below describe OpenVSP Version 2 perfectly. The information ist the best available to learn OpenVSP Version 2.

Video Tutorial 6: Introduction to Vorview
The Vorview/Vorlax capability in OpenVSP Version 2 is kept around only as a legacy to support users who had access to VSP before it was released as open source. The OpenVSP team at NASA was not able to gain the rights to distribute Vorlax openly. Use extended analysis features from OpenVSP Version 3 instead.
Aircraft displayed in OpenVSP Version 2
Aircraft displayed in OpenVSP Version 3
OpenVSP Version 2 displays the aircraft very well - or even better than version 3. In both versions, the color of aircraft components can be chosen and the 3D lighting can be ajusted.
