With this function you create sealing membranes which can be modified similar to polylines with grips or by stretching. You can create membranes with various possible constructions.
Dialog box Membrane (layer)
The same dialog box appears as layer instead of slide when you edit the properties of a layer in Edit infill.
In the dialog box you will find on the left side the Display section with the dynamic preview. On the right side you can see the Operating section with the tabs Properties and Manager. The properties are object specific; the manager is the same for all objects.
Dialog box Layer
db_scc_foli
Display section
At the top left there are two buttons for favorites. You will find further information on this in the section Saving and using favorites.
The preview is primarily intended for visual checks and shows the part with the set properties.
Dialog box section Form
Outline
Creates a membrane without infill.
Filled
Creates a filled membrane (here the option Division is taken into account).
Lined
Produces a lined membrane.
Hatched
Creates a membrane with hatched infill. When you select a material, the material-dependent hatching is used.
You will find a detailed description of the functions of the manager in the Chapter Management of objects.
End of program
When you click OK, the dialog box is terminated. An input request follows depending on the type of construction selected.
You can terminate the Dialog box Membrane (layer) directly after calling the command by pressing the Enter key to access the input request. In this way you have the possibility of very quickly creating several membranes with identical properties.
E.g.: You have just created a film with certain properties. Now press the Enter key twice (once to repeat the Membrane command and a second time to terminate the dialog box immediately) and draw a further membrane with the same properties.
Input request
Type of construction option Normal
Specify starting point of membrane or [?]:
Specify the starting point of the membrane.
With the option ? you call the help.
Specify direction or [Undo/?]:
Specify the direction of the membrane.
Use the option Undoto repeat the previous input request.
Specify next point or [Back/?]:
Specify the second point of the membrane. If you deviate from the previously specified direction, the membrane is created with a tangential arc to the direction. The membrane runs straight in the specified direction.
Specify side for wall thickness or [Central/Undo/?] <Central>:
Specify on which side the membrane is to be drawn.
Use the option Central to draw the membrane centrally to the specified points.
Specify next point or [Back/?]:
Specify the next membrane point. The last membrane point is always used for the default direction. If you deviate from this direction, the membrane is created with a tangential arc.
This input request is repeated. Press the Enter key to terminate the command.
ath_foli_normal
Membrane option Normal
Input request
Type of construction option Fit
Specify starting point of membrane or [?]:
Specify the starting point of the membrane.
With the option ? you call the help.
Specify next point or [Arc point/Undo/Direction/Length/?]:
Specify the second membrane point.
Use the option Undoto repeat the previous input request.
Specify side for wall thickness or [Central/Undo/?] <Central>:
Specify on which side the membrane is to be drawn.
The wall thickness is produced centrally to the membrane with the option Central.
Specify next point or [Arc point/Undo/Direction/Angle/Length/?]:
Specify the second membrane point.
With the Option Arc point you can specify an arc point. Further input requests follow.
With Option Direction you can change the direction for the limb. Further input requests follow.
With the Option Angle you can specify an angle. Further input requests follow.
With Option Length you can specify the length for the limb. Further input requests follow.
This input request is repeated. Press the Enter key to terminate the command.
Specify side for wall thickness or [Central/Same/Undo/?] <Same>:
Specify on which side the membrane is to be drawn.
Press the Enter key to draw the membrane on the side previously specified.
Option Arc point
Specify arc point or [Line/Undo/?]:
Specify an arc point.
With the option Line you can draw straight membrane segments.
Specify endpoint of the arc or [Undo/Line/Arc point/?]:
Enter the end point of the arc or select an option.
Option Direction
Specify direction or [Length/Angle/Point/Undo/?]:
Specify the direction of the membrane segment or select an option.
Specify limb length or [Direction/Angle/Point/Undo/?]:
Define the length of the membrane segment by pointing with the mouse or entering the length.
Option Angle
Specify angle or [Length/Direction/Point/Undo/?]:
Define the angle relative to the last membrane section by pointing with the mouse or entering the angle or selecting an option.
Specify limb length or [Direction/Angle/Point/Undo/?]:
Define the length of the membrane segment by pointing with the mouse or entering the length or selecting an option.
Option Length
Specify limb length or [Direction/Angle/Point/Undo/?]:
Define the length of the membrane segment by pointing with the mouse or entering the length or selecting an option.
Specify angle or [Length/Direction/Point/Undo/?]:
Define the angle relative to the last membrane section by pointing with the mouse or entering the angle or selecting an option.
ath_foli_einpassen
Membrane option Fit
Input request
Type of construction option Object selection
Select Polyline or [?]:
Select the polyline object which is to be converted to a membrane.
With the option ? you call the help.
Specify side for wall thickness or [Central/?] <Central>:
Specify on which side the membrane is to be drawn.
The wall thickness is produced centrally to the membrane with the option Central.
Delete polyline [Yes/No/?] <Yes>:
With the option Yes you delete the existing polyline.
The polyline is retained with the option No.
Notes
• You can change a membrane by stretching or with grips. When stretched, the membrane behaves like a polyline.
