Tangent to Circles or Arcs
In RFEM, various tools for modeling are available. The modeling functions make it possible to quickly represent complex structures efficiently in the program. The connection of two circles or arcs for example can be generated with the function ‘Tangent to Circles or Arcs’.
When selecting two arcs the program suggests all available tangents. By selecting the relevant line the program generates it in the system. In addition, it is possible to remove the remaining portions of the arcs automatically by means of the option ‘Trim arcs’.

Depending on stiffness, mass, and damping, structures react differently to wind action.
- Why is no support force displayed even though I have bedded the member?
Is it possible to change the font size of dimensions?
- I would like to apply only to a part of the surface a rectangular load. How to do it?
Which units are specified in the result display of the support reactions (kN or kN/m)? A note about this is missing in the graphic.
In the case that the support reactions are given in kN/m, for which distance does the value apply?
- I design a cross-section created in the SHAPE‑THIN program by using the RF‑STEEL EC3 add-on module, but the program shows the error message "ER006 Invalid type of c/t-part for cross-section of type General." What can I do?
- I would like to calculate a multi-span beam. Is it possible to automatically apply imposed loads by span (for the design of the largest supporting moment and moment in the span)?
Is it possible to specify shrinkage effects as loads?
How the shear deformation of a member can be taken into account?
Is it possible to calculate American steel cross-sections?
How can I only display cross-section names in the panel for cross-section colors, without the standard and steel grade?
