With Spider Pro you will be able to: 

  • Create rigid links for multiple column-slab joints with diverse options
  • Create rigid links for multiple beam-wall joints
  • Create multiple drop panels and connect them to the slab using rigid links
  • Create rigid links along the length of the bar to connect bars to panels or to connect panels with panels
  • Convert selected columns to walls
  • Convert all rigid links in the model to bars with the predefined section
  • Easily modify the length of the selected bars
  • Convert beams to shells with numerous settings
  • Easily modify load contour for selected loads
  • Easily modify the contour of the panel or opening
  • Select panels according to the applied vertical load value. The selection is limited to planar load and uniform planar load on a contour.
  • Switch off automatic panel selection in the contour plane for selected load case
  • Easily create stairs according to the selected rectangular contour. The contour shall have 4 vertices.
  • Easily check the area loads and create colorful load maps  
  • Easily change the start or end node for selected bars
  • Align coordinates for nodes based on the selected node
  • Measure distance between 2 nodes
  • Convert walls to columns
  • Convert walls to loads


Note: This app uses a custom installer (and not the standard App Store installer).

About This Version

Version 2.0.0, 4/4/2024
What's new in this version: - Implemented conversion of walls to columns - Improved algorithm of rigid links creation along wall edge. Now it is possible to create rigid links also along the bottom edge of the wall, top and bottom edges can be inclined - Implemented conversion of walls to loads with the possibility to specify the density of the wall material - Added rigid panel label creation menu in the dialog Column 2

    Can't imagine my work at the RSA without this app.

    It's impossible.

    I save my time and receive a better results.

    If you dont use this app you doesnt love youself and your life.

    In one click you can receive rigid link or panel at top or bottom in slab - very useful and nescesary

    Strongly recommend to use this APP.

    Remember it name - SPIDER PRO

    Many thanks, ROMAN. You are THE BEST

  • The BEST app for ROBOT concrete
    Cristina Martínez | August 17, 2022

    All the most important settings of the calculation model in one place.
    All that makes your model more accurate and consistent with its realistic operation throughout its life cycle. But all these settings can be made in a few clicks.

    As a result, you will receive a clear calculation model in the shortest possible time.

    ¡Muchos gracias Roman and keep up the good work on improving the app!


  • A great APP for RSA
    Babak Moussavian | March 24, 2021 Verified Download (What's this?)

    Spider Pro is a powerful and userfreindly APP enhancing creating difficult details fast and precise.

    I have been using Spider Pro since I got this APP and find it very useful.

    Very easy to use and very stable.

    Spider Pro makes RSA even better!      

  • Мery convenient application
    OLEG POPOV | February 05, 2021 Verified Download (What's this?)

    A very convenient application for creating a design model that is closer to the actual one and getting accordingly more correct results.

    Huge thanks to Roman for his work. I recommend this application to everyone.

  • Most Useful App
    Ahmad Said | July 01, 2020 Verified Download (What's this?)

    I was working on some quick fast job and thanks to SpiderPro that made me save lots time, especially when you use rigid links,stairs and drop panels.

    SpiderPro is a powerfull app and once you use it you'll use it more..

    Thanks a lot Roman and please keep your effort on it mate. 

  • Great tool for RSA
    Igor Saltykov | March 26, 2020

    One of the best tool for RSA. 

    A lot of very useful functions here, like in Express tools for AutoCAD.

    Strongly recommended!

  • Best tool for RSA
    Filipe Ribeiro | December 09, 2019 Verified Download (What's this?)

    Dear RSA users. This app is a must have for RSA since it offer an unique set of tools that are very uselfull and improves the speed of the moddeling workflow. 

    FIVE START without a question.

    Roman, keep up with your waesome work.

  • Best App at the moment
    Ilja Jevglevski | October 24, 2019

    Started to use free version of Spyder and was very impressed with its potential. When PRO version came out I immediately acquired it and use untill now in my everyday work. Very powerful tool! Highly recommended to everyone who deal with concrete modelling in Robot. Saves a lot of time and your calculation results are much more accurate with it. 

  • Super App
    Dmitry Koynov | October 04, 2019

    J'utilise cette application depuis longtemps. Ca facilite la modélisation des structures. L'auteur ajoute de temps en temps des nouvelles fonctionnalités. Bonne chance dans le développement du projet!

  • The greatest tool out there for RSA
    Joel Carvalho | August 05, 2019

    I started using Spider Pro mainly for flat slab design, and it has been an amazing tool when you need to generate rigid links between columns and slab. All the other functions it comes with are also very usefull and can save you a lot of time. This is one of the greatest tools, if not the greatest, out there for RSA and I can really recommend it.

    STEFANO ROMEO PASQUINI | June 27, 2019

    Dear Robot Users, I got SpiderPro almost two years ago, and whit it I saved hundreds hours in modeling....I find that there are a lot of incredibly useful functions, and the development is always "on the wave".

    I want to strongly advice this tool to everybody who use Robot.
