Can’t get through to support email so hopefully developer reads this.Tried working with sample frame after last update four days ago. Noticed example lists two materials but only one shows up when you select beams from diagram. Tried creating new frame but get kicked out of program when trying to creat second node.Help would be appreciated.Thanks for fixing nodes but now the app shuts down when attempting to set membersWould really help if app support link would work as your other programs are great and having to ask for help through a review comment does not look good
Don’t waste your money - doesn’t work

Program does not allow input of members after establishing all nodes. Thumbs down big time!👎🏻👎🏻👎🏻

Can’t pass from the second node.
Good app, could be improved

The input is easy to navigate. Would be greatly improved if member end connectivity (fixed or pinned) could be an option. That's the biggest missing option. Also would be great if uniform loads could be input over a horizontal projection as opposed to along the length of the slope. As it is the loading has to be factored by cos(angle) before input for sloping members.
• Smarter PDF Report Export
Choose which report sections to include before generating a PDF. For large grid frames, you can also select member ranges for Member Stiffness and Member Forces Calculation sections.
• PDF Page Estimate
The PDF export dialog now shows an estimated total page count before generation.
• Improved Analysis Validation
AFrame Pro now checks frame data before running analysis and shows soft warnings for missing loads, unassigned nodes or members, invalid material data, and unstable support conditions.
• Cleaner Equilibrium Checks
Tiny numerical round-off values are hidden from equilibrium equations, and zero-arm moment terms are no longer displayed.
• Better Frame Free-Body Diagram Colors
Loads and reactions now use clearer axis-based colors in analysis views.
• General Report and UI Improvements
Analysis reports, unit formatting, canvas display, and PDF output have been refined for a smoother workflow.
