| Optional an unlimited number of views can be made. The camera position and all display settings will be stored per view. All views are also saved in the project file input file so that they can be displayed and or included in the output again when the project is reopened. You can of course rename all views. In the output selection you can select the views to be included in the output. All 3d view image of Geometry Loads and Results are automatically placed in the right place. When generating output all selected 3d view images are also saved as a png-file in the map where the project file input file is saved.

| =====Find=====
| |
| Β | |
| [[File:Search.png | 30px]]
| |
| Β | |
| The Find feature makes it quick and easy to find a node, beam or profiles.
| |
| Β | |
| Β | |
| '''How does that work?'''
| |
| Β | |
| You choose Nodes, Beams or Profiles. The combo box is filled with the visible nodes, beams or profiles. The whole model is drawn transparently except for the node, beam or profiles you are looking for. It is very intuitive.
| |
|
| |
| [[File:Image 2022-08-16 145554625.png | 200px]]
| |
| Β | |
| To change the node or beam you can also click on the node or beam in the 3d model.
| |
| Β | |
| ====Dockable windows====
| |
| Β | |
| '''What are these?''' Dockable windows are windows that can be moved freely or placed on fixed spots.Β (left/right/top/bottom of the screen)
| |
| Β | |
| Β | |
| The tables for '''Geometry''' (Grid lines / Levels, Nodes, Profiles and Beams) and the tables for '''Loads''' ( Load combinations, Beam lodes, Node loads and Combinations) can be displayed or not.
| |
| Β | |
| Β | |
| You can enter your construction fully graphically, whereby the use of tables is not really necessary. Nevertheless it can be handy to see, for instance,Β the node coordinates in tables. This is possible. But in contradictory to many other programs you can also make any changes in these tables. It does not matter. Graphical drawing or numerical input via tables can be done simultaneously. After each change, all tables are updated and the construction is redrawn. Of course the undo and redo functions still work.
| |
| Β | |
|
| |
| The windows can be set as 'floating' (in a random position but also outside the screen) or can be 'docked' left/right/top/bottom in the main window. This gives you much freedom. You can decide for yourself what you find most pleasant. The program remembers this setting, so you only have to do this one time. Of course you can always change this.
| |
| Β | |
|
| |
| For example, when you have two computer monitor, you can show the construction graphically in full screen on one monitor, and show the tables on the other monitor.
| |
| Β | |
| ====Dockable windows====
| |
| Β | |
| Changing dimensions or values in the graphical view
| |
| Β | |
| #Move your cursor on the number in the dimension line.
| |
| #When the dimension line gets its focus, the number is viewed '''bold'''. The color of the dimension changes from gray to black.
| |
| #Press left mouse button. A dialog appears with the number to be edited.[[File:editor.png | 100px]]
| |
| #Change the value.
| |
| #Press. [[File:Vink v2.png | 30px]] The dialog will be closed and the dimension has been changed.
| |
|
| |
| or
| |
| Press [[File:kruis.png | 30px]] to cancel.
| |
| Β | |
| ====Beam grid concrete====
| |
| Β | |
| With '''XFEM4U''' you can easily design a beam grid or a piled concrete foundation, and optimize its design.
| |
| Β | |
| [[File:Balkenrooster.png | 600px]]
| |
| Β | |
| =====Pile distances=====
| |
| Β | |
| In this screen you can adjust the pile distances. You can do this in 2 ways.

| Β | |
| Β | |
| #by clicking on the dimension line and entering a different distance, or
| |
| #by dragging the support point graphically with the mouse.
| |
| Β | |
| Β | |
| After changing this, the beam grid is automatically recalculated and so you see the result immediately. immediately.

| When you save a project, '''XFEM4U''' makes a backup copy of the previous version of the project (that is, the project file before the current save). This backup copy has the name "_backup<nnn>_"<project_name>.xfem, where <nnn> is a 3-digit number indicating how many times the file has been saved. The backup files reside in the same folder as the project file. The number of backup files is 3.

| is the number of columns in a row including only those columns which carry a vertical load NEd not less than 50% of the average value of the column in the vertical plane considered
| |
| Β | |
| See Eurocode EN 1993-1-1 art. 5.3.2 Imperfections for global analysis of frames.
| |
| In '''XFEM4U''' all node coordinates will automatically be corrected/adjusted with +dx and -dx. So all UGT combinations will be automatically calculated twice. One with imperfections in positive direction, and one with imperfections in negative direction. Furthermore, in '''XFEM4U''' all Eurocode design checks are based on a geometrically non-linear analysis. Imperfections (initial sway imperfections) will be automatically included in calculating load combination(s). This is a very accurate calculation method and is applicable for every type of frame. Sway or braced/non-sway frames. In addition, there is no need to calculate (error-prone) buckling lengths any more. The geometrical non- linear analysis (Second-order analysis) ensures global buckling stability check.
| |
| Β | |
| In '''XFEM4U''' global initial sway imperfections according to EN 1993-1-1 art. 5.3.2 (3) a) are taken into account automatically. The beamΒ imperfectionsΒ according to EN 1993-1-1 art. 5.3.2 (3) b) are NOT taken into account. This means that the individual stability of all beams needs to be checked according 6.3. The buckling length can be assumed equal to its beam length since the calculation is based on analysis, including global second order effects and global imperfections. See EN 1993-1-1 art. 5.2.2 (7) b).

| =====Optimize steel profiles=====
| |
| Β | |

| |
| Β | |
| With the function optimization you can very easy and quick create an optimal design of your steel construction. This function can spare you a lot of steel kilos.
| |
| Β | |
|
| |
| '''How does that work?'''
| |
| Β | |
| You will go through all the profiles (in the table '''Profiles''' ) as you have inserted before. See Beams
| |
| Β | |
| The alternatives per profile will be shown directly. From these alternatives you can select another profile.
| |
| Β | |
| [[File:optimalisation.png | 500px]]

| Here you select the profile type (or group) in which there can be searched for alternative profiles.
| |
| Β | |
| Β | |
| '''Maximum number per type'''
| |
| Β | |
| Here you can enter the maximum amount of alternatives per profile type. Standard this value is at 3, but you can vary this value.
| |
| Β | |
| [[File:select.png | 80px]]
| |
| Β | |
| Hereby you choose a profile from the right table ''Alternatives''. You can also double click on the line in the table to choose the profile
| |
| Β | |
| Β | |
| '''Alternatives'''
| |
| Β | |
| [[File:Alternatives.png | 350px]]
| |
| Β | |
|
| |
| Β | |
| In this table the possible alternatives are directly shown. By default the table is sorted by the unity check (u.c.). This unity check is the normative check according to the Eurocode EN1993.Β It is also possible to sort the table by profile name or weight by clicking on the column text.
| |
| Β | |
|
| |
| Β | |
| Remark: By changing the moment of inertia, the force distribution also changes. The optimization function does not take this in to account. It could be possible that the new selected profiles will not be sufficient for your design and you have to use the optimization again. However, you will experience that the optimal design will be determined quick and easy.
