About the Polysolid Tool
The Polysolid tool lets you create wall solids by selecting a start point, an endpoint and entering a height. Note that, in BricsCAD BIM, always start by creating the geometry first and adding materials or compositions later. This way there is no need to worry about details when modeling a preliminary design.
For more information about this command, visit the Command Reference article PolySolid.
Procedure: Create a simple wall
Launch the Polysolid tool.
Select a start point, the footprint (1) of the wall displays automatically.
Move the cursor in the desired direction, the current length value displays in the length dynamic entry field (2).
Select an endpoint or enter a value in the “dynamic input field” and press Enter. The footprint (3) of the adjacent wall displays automatically. You can keep creating adjoining wall segments by clicking or entering values in the dynamic input field.
Press enter once more or right-click. The height of the wall displays dynamically in the height field (4). Here, you can change the default height of the wall. To change the width of the wall, use the width field (5). You can switch between the two dynamic input fields by pressing TAB.
To change the justification of the wall hit CTRL while the ’Polysolid justification Hotkey Assistant widget‘ appears at the bottom of the screen.
Note The width and height of the previous wall will be the new default values of the next Polysolid.
Procedure: Creating a curved wall
Launch the Polysolid tool and select a start point, move the cursor to set the length or click to set the endpoint. To create a curved wall, select "Draw Arc" (9).
Now move the cursor in the desired direction to curve the wall. Enter a value in the “dynamic input field” to set the degree and length of the arc (10). Press enter.
You can continue creating curved, adjoining wall segments by clicking or entering values in the dynamic input fields. To go back to drawing straight wall segments, click "Draw Lines" in the options dialog (11).
Press enter once more or right-click. The height of the wall displays dynamically in the height field. Here, you can change the default height of the wall. To change the width of the wall, use the width field. You can switch between the two dynamic input fields by pressing TAB.
Procedure: Using an existing 2D plan to create walls

Using an existing 2D plan view enables you to create a wall element in 3D.
Click the “Polysolid” tool from the Quad and type “E” on the command line or select “Entity” in the prompt menu. Using the “Entity” option in Polysolid enables you to create 3D geometry from a 2D layout.
Choose a 2D linear entity which will be the Polysolid base.
Lines, open and closed polylines, arcs, circles, ellipses, elliptical arcs, and splines are accepted as a polysolid bases.
Move the solid up or down and left-click to set the height of the wall, enter a value in the dynamic input field, or right-click to accept the default value.
The current width of the wall appears in the Width Field. Press Tab to change the default value of the width.
The Hotkey Assistant appears and displays the possible justification options. Press CTRL to cycle through the wall justification options.
About the BimConnect Tool
The BimConnect tools enable you to connect one wall to another element.
For more information about this command, visit the Command Reference article LConnect.
Procedure: Connecting two walls
Tutorial: How to connect walls

Select two wall elements and apply the LConnect tool.
When two walls intersect, a miter connection between two walls will be automatically created by default.
The following illustration shows the wall elements before (12) and after (13) applying the LConnect tool.
The layout of the wall connections can be changed by using the ‘LConnect HotKeyAssistant widget’.
This widget appears at the bottom of the screen with the available options after you apply the LConnect tool to the selected walls and HKA is turned on in the status-bar.
The wall connection can be made to bisector L-connection (14), L parallel type 1 (15) or L parallel type 2 (16). Switch between the options by pressing CTRL.
The selected connection type is indicated by a blue frame.
When the bisector L-connection is selected, the walls are connected at an angle of 45°.
Bisector L-connection (miter)
When the L parallel type 1 or type 2 connections are selected, the walls are connected at an angle of 90°.
Parallel L-connection 1 Parallel L-connection 2
Press Enter to accept the current connection type or press CTRL to cycle through the possible connection options.
Connecting walls to other elements
The Connect with nearest tool allows you to connect the minor face of a wall to the major face of another element, regardless of the orientation of the faces. This tool can be used to connect the top face of a wall to a roof, the bottom face to a slab or the side face of a slab to a wall.
Note: Before using the Connect with nearest tool, make sure the Select Faces option is enabled in the selection mode settings.
For more information about this command, visit the Command Reference article TConnect.
Procedure: Creating T- connections between two walls
In the drawing area, highlight the face or faces that need to be connected to another wall (17).
Use the Connect with nearest tool from the Quad.
The Connect with nearest tool automatically makes a T-connection (18) between the two walls by moving the face of the first wall to the nearest face of the other wall.
About the Select Aligned Faces Tool
The Connect with nearest tool can also be used to connect the multiple faces of a wall to the nearest face of another element. To do this use Select aligned faces tool. This tool enables you to automatically highlight all faces that are coplanar with the current selection.
For more information about this command, visit the Command Reference article SelectAlignedFaces.
Procedure: Connecting multiple faces of the wall to the roof slab
In the drawing area, highlight the top face of one of the walls (19) and then click the Select aligned faces tool from the Quad. All faces, aligned to the current selection, will be selected (20).
Launch the Connect with nearest tool. The top faces of the wall are attached to the roof (21).
