• ### Are the loads in the plan view oriented with a cross downwards and those with a circle facing upwards?

New FAQ 003227 EN-US

Whether you display a load with a cross or a circle is decided by the viewing direction. If the viewing direction of the load follows, a cross is displayed. However, if the viewing direction is opposite to the load direction, a circle is displayed.

• ### How can I graphically visualize the different surface supports and display them in the printout report?

New FAQ 003226 EN-US

In the project navigator - Display, select the Colors in graphic according to -> Visibility option (see Figure 1).
Furthermore, in the Project Navigator - Views, you have to set the Visibility for Surfaces by Supports (see Figure 2).
Then, you can display the table with the surface supports as well as the colored representation of the surface supports including the legend in the printout report (see Figure 3).

• ### Why does the Cutting Length + Compensation result in a shorter model length?

New FAQ 003225 EN-US

The integral warping process in RF-CUTTING-PATH does not smooth every cut individually, but rather the complete model geometry in one step. The line type of the respective cutting units also has an effect on the neighboring cuts.

In the case of a welding line between two blanks, the program ensures a line uniformity in the connecting zone. The geometry of the cuttings is determined so that the relevant edge lengths of the cuttings are identical.

The "Limit line" line type allows for an independent view of the subsequent cutting units. The length of the boundary lines in the neighboring area may be different.

Basically, the blank units have the following conditions

1. Surface compensation,
2. Edge line and edge compensation
3. Edge Type
together. These requirements are numerically precisely represented in the integral calculation. Especially for blanks in the edge area, the process can usually not determine a universally applicable shape due to too many boundary conditions.

In this case, the program is approaching an optimal solution. The affected cuts are particularly noticeable due to their curvature in relation to the uncompensated solution. Due to the greater degree of modification, these blanks also differ slightly from the defined compensation specifications, but are in equilibrium with all other blanks due to the overall calculation.

Deformation Process

• ### Is it possible to evaluate deformations and internal forces of hinges?

New FAQ 003224 EN-US

For the RFEM Version 5.17, there is a graphical output (only for line hinges and line releases) and a table output. The latter can be found in the following tables:

• 4.45 Line Hinges - Deformations
• 4.46 Line Hinges - Forces
• 4.47 Member Hinges - Deformations
• 4.48 Member Hinges - Forces
• 4.49 Nodal Releases - Deformations
• 4.50 Nodal Releases - Forces
• 4.51 Line releases - deformations
• 4.52 Line Releases - Forces

• ### By which length is the boundary line compensation distributed in the surface?

New FAQ 003223 EN-US

The program does not define a fixed length for distributing the boundary line compensation. Rather, the compensation is defined at the boundary line nodes and reacts in conjunction with the integral flattening depending on the geometry and stiffness.

In the calculation, the integral flattening considers all compensatory strains on the surface and on the edges with the strains of flattening itself.

Deformation Process

• ### Is it possible to read values from the table in order to use them for parametric input?

New FAQ 003222 EN-US

With the entry "& refcell" with the syntax "$table number (cell description)", you can select values from the table. Figure 4.01 shows a member with a length of 4.20 m. The length is shown in Table "1.17 Members" in cell L1. This value can now be used in the parameter list or the formula editor. For this, use the following formula for the system shown in Figure 01:$1.17 (L1)

Reading cells from the results table is not possible because of the circularity.

• ### How can I find a shape found with RF form-finding?

New FAQ 003221 EN-US

This requires the RF-CUTTING-PATTERN RFEM add-on module. This calculates and organizes cutting patterns for membrane structures. The boundary conditions of the cutting patterns on the curved geometry are determined by the boundary lines and independent plane or geodesic cutting lines. For detailed information, see the links below and the videos.

• ### What is meant by the Brickwork Class in the material library for masonry according to EN 1996-1-1?

New FAQ 003219 EN-US

Depending on the geometric requirements of the bricks, these are integrated into classes 1 - 4. All geometric requirements for the brick classes are listed in Table 3.1 of the EN 1996-1-1. An example of assigning the classes according to the total percentage of the brick holes (% of the gross volume) is as follows:

Class 1 (all stones)
≤ 25

Class 2
vertical hole ratio> 25; ≤ 55

Class 3
vertical hole ratio ≥ 25; ≤ 70

Class 4
horizontal hole ratio> 25; ≤ 70

• ### Where is it possible to define the reference height for the reduction factors of the snow load according to SIA 260?

New FAQ 003218 EN-US

The reference height can be defined in the factors for the standard SIA 260. They are set in the general data (see Figure 01). The desired reference height is available in the "Combination Factors" tab.
