CAD/Revit Teacher

Hi all,

I hope you’re doing well and Happy Fourth! I’m a teacher in NY who teaches “Autodesk Inventor and Revit” at the high school level. Two questions:

  1. I make 129K forgive me if this is too personal but how does that compare to industry architects?

  2. What are some projects in 2026 you recommend I try with my students for both Inventor and Revit?

Really enjoy Mechanical Drafting and Architecture but man, the kiddos are burning me out haha.

Thanks so much!

P.S. I Teach in Westchester County, NY.

Free and Open Source alternative to Inventor

I have been using inventor for the last 15 years and I always wished to have an open source alternative which would not lock me to windows.

So I decided to create my own: Oblikovati, open source, lightweight and runs on Linux, Mac and Windows.

Oblikovati has also an AddIn comparable to Inventor, and I have been experimenting creating some addins for multi-physics FEA and CAM.

It is still on early stages, since it was built from ground up, not using any kernel libraries, but it is quite usable already.

Development builds available on GitHub: https://github.com/Oblikovati/Oblikovati

Does anyone use any specific naming conventions for their projects? Mine always end up quite messy.

Need help making my files more organised. My project files end up messy and being called “example 1” and then “example 1 final” and random stuff like that. Curious what others use.

Autodesk Inventor (using adskNLM.exe) suddenly no longer works on both PCs on my network

I installed Inventor 2023 on 1 Desktop and 1 Laptop in my workshop. They have been running fine for a couple years. Suddenly, both failed to start Inventor on the same day. WTF. Anyone have a clue? Did autodesk find a way to disable these?

Getting similar displacement results in between AR400 and corten steel plates

I'm having quarter inch plate about 26" by 26" laser cut into a grate cover in a foot traffic area. Each outer edge is supported by a one inch lip and I have a 4"x12" ellipse(rough shape of a foot) where the 200lb load is. I ran an analysis assigning appropriate yield/tensile strength figures for each material and I'm getting the same Y Displacement figure 0.06296in for both corten and AR400 steel even though AR400 has roughly three times the tensile and yield strength. Does this seem right, is it just a product of a "very small" load over a "small" plate?

Former Lead Developer of Inventor Nastran here and Happy to Help.

Hi everyone,

I was one of the principal engineers who developed Autodesk Inventor Nastran (originally NEi Nastran) from 1987 to 2023 working primarily on the solver. If you’re stuck on a problem, whether it’s meshing, contacts, nonlinear analysis, bolt pretension, composites, dynamics, vibration, buckling, or interpreting results, I’ll do my best to help here in the thread. If it’s something that requires looking at confidential models or is too involved for Reddit, we can discuss other options privately. I don’t check Reddit constantly, but I’ll answer as many questions as I can. Looking forward to helping the community.

Extension of educational license randomly declined

I'm a member of a university faculty (not a student) and I've been on an educational license for many years. So far Autodesk has always accepted a letter from the faculty head as a proof tor the educational letter. The letter states that I'm a faculty member and that I use Inventor for educational / training purposes. This year, out of the blue, they refused to accept this letter and claimed that it is "not an official document". This is nonsense but there is no way for me to object because the verification process is automatized and the decision is sent from a do-not-reply address. I've tried to resubmit the document with an added note explaining that this is in fact an official document but it got rejected again within a minute. I'm a bit at a loss here. I can't call Autodesk and complain because I'm not on a subscription and the university folks also don't know how to handle it. What can I do?

Inventor: Modeled threads for 3D printing?

Is there a usable workaround in Inventor to quickly create many threads as real geometry?

I need printed threads, not inserts or alternatives. M3x0.5 has been working reliably for me for years.

ThreadModeler/ThreadCreator does not work properly for me in Inventor 2027.

Is there a practical solution using an add-in, iLogic, iFeature, or macro?

Ideally, Inventor would have an export option: cosmetic threads in the model, real threads only for STL/3MF export.

In Creo i use UDF's to choose and insert (para)metric threads

How do you guys go about Mirrores Assemblies?

So, the kind of work I do, there are often assemblies that are mirror of each other!

One workflow thats in my mind but havent really used is:

  1. I can just use mirror command to mirror all the parts in the parent assembly to be copied as mirror and then save it, that would be linked to the parent parts.
    Now that gives two porblems;
    A. There are always many parts that aren't the mirror but are the same as the parent part so obviously I wouldnt select those while mirroring, because I wouldnt want different part numbers for same parts, and have to manually add them later on.
    B. The mates wont copy along in the mirror assembly and evry part is going to be either loose or grounded, which really is usless, as I would have to add all the mates again!

  2. The second workflow, which I always do, is just to manually mirror the parts I need in the part environment and just create the whole mirrored assembly again.

I have a feeling that there gotta be a smarter more efficient workflow which I dont know of.
So, any help?

How would you go creating this gear?

Greetings.

I have been trying to build this shape , but i dont get the results i want.

if you look at the gear teeth, it follows a straight path over the surface

my method:

1draw an auxiliary plane so i can draw a straight line and project it onto the surface

2draw the shape, touching the path.

3- use the proyected curve to sweep around the cylinder . its aguided sweep.

method 2 - plane tangent to projected curved line, guided sweep the triangle and the shape also twist.

problem is: the shape twists..

how would you create this gear?

its has to look like this gear,

Inventor 2024 / 2025 / 2026 / 2027 Addin "Checkup"

Hi there

I have spent the last Months of my Free Time with Designing an Inventor Addin Called "Checkup". Designed means i used LLMs to get it to Create what i had in Mind. It took countless Iterations, Tests and much Thinking it through until i was Satisfied. I Believe at this Moment i can Share it or rather make it Public.

https://github.com/starsheriff0815/checkupaddin

https://github.com/Starsheriff0815/CheckupAddin/blob/main/docs%2FGetting-Started.md

This is and will be always Free!

You can find on the Repo the Full Code Project aswell as Pre-Build ZIPs if you just want to use the Addin. There is Extensive Documentation already there. For the User Documentation, i still need to Fill up the WIP Parts. But the Basics are already there. For everyone who wants to Modify the Code the "Technical Design Documentation" is where you should Start.

After quite some Years Lurking all the wonderfull Community driven Blogs, Boards and Knowledge Bases. I hope i can give a little back by Sharing this Addin.

Solution needed - NAS no longer supported

In our office we used Inventor 2011 from 2011 until last year when we updated to Inventor 2025. We store and work from a NAS and have noticed both permanent performance issues and occasional crashes when working on large assemblies after updating to Inventor 2025. We had no issues in Inventor 2011.

Found a forum post claiming NAS support was dropped in 2021 version which seems to be true as we had no issues when testing Inventor 2020. Post recommended using Windows server instead.

Most people seem to recommend using vault which is unfortunately not an option for our workflow.

Can anybody using Windows server share their experiences working as a small team on only the network drive? (No copying to local machine)

On a day to day basis we are 4-8 people working on the same project and workers and NAS are on premises so no cloud or remote access are used.

We only work on local machines when converting files from customer and plant point clouds.

Thanks in advance for any help!

TL;DR Working with files stored on a NAS is no longer supported, will switching to Windows server fix performance issues?

Inventor Nastran – Shell midsurface not interacting correctly with another shell? Need help with one last issue

I'm working on the final part of my research project and I'm stuck with what seems to be my last issue.

I'm simulating a compression load applied from the bottom of a plate reinforced with two stiffeners arranged in a cross. One stiffener (the horizontal one in the image) was originally modeled as a solid, but I converted it to a shell using the Midsurface command. The vertical stiffener, however, was modeled directly as a shell surface.

After running the analysis, it looks like the bottom plate isn't interacting correctly with the horizontal stiffener. In the results, that stiffener barely carries any load (it stays mostly blue), which makes me think it may not actually be connected to the surrounding shell elements or that the shell intersections are not being recognized.

I've already tried different contact definitions, continuous meshing, and other approaches, but I still can't get this region to behave correctly.

Has anyone experienced something similar in Inventor Nastran? Is there a recommended way to connect a solid created from a midsurface with another shell that intersects it?

At this point, I feel like I've tried everything I could think of: different surface connectors, bonded and offset contacts, checking and rebuilding the mesh, refining the mesh size, and several other modeling approaches, but nothing seems to fix this specific region.

This is literally the last issue preventing me from finishing my research. I built the entire model by myself, so I'd really appreciate any advice from someone with more experience.

I have an inquiry regarding Inventor drawing work.

Hello.

I would like to assign different colors to individual purchased parts (cylinders, motors, LMs, etc.) in Inventor assembly drawings.

Currently, I am applying the color by right-clicking a specific purchased part model in the 'Model Browser' on the left and selecting 'Properties'.

While this works, it requires repeating the same process for every view.

This seems too time-consuming and inefficient, so I was wondering if there is an easier way to handle this.

Have a nice day.

Shell elements separating during deformation – How can I make them behave as a single welded structure in Inventor Nastran?

https://preview.redd.it/ip5w7v5lw69h1.png?width=770&format=png&auto=webp&s=83b4fe94fd3e512a113d752baaa044e0ce29bae6

Hi everyone,

I'm working on a stiffened plate model in Inventor Nastran using shell elements. The model consists of a plate and intersecting stiffeners represented as shells.

A compressive load is applied from below, and as the structure deforms upward, I notice that the shell elements begin to separate at their intersections instead of behaving as a single continuous structure. Since these components represent welded structural members, I would expect them to remain fully connected during deformation.

The geometry appears to be touching, but I'm not sure whether the shells are actually sharing nodes or if I need to define an additional connection.

My questions are:

  • What is the correct way to connect intersecting shell elements in Inventor Nastran?
  • Should I use Continuous Mesh, Bonded Contact, Edge-to-Edge connections, or another approach?
  • How can I verify that the shell elements are truly connected and behaving as a single piece?

I've attached images of the mesh and results for reference.

Any advice would be greatly appreciated. Thanks!
