Vectary - Step by step

Step 1: Access the website https://www.vectary.com/.

Step 2: Click on "Get started for free".

Step 3: Create your profile; I opted for "signing in with Google".

Step 4: Once signed in, click on "New Project".

Step 5: Select the middlebox labeled "Import (STEP, FBX, OBJ...)". Supported formats include FBX, glTF, OBJ, stl, dae, hdr, jpg, png, or SVG.

Step 6: Choose the format you wish to work with, click on "Choose File...", then select "Open".

Step 7: Adjust the size of the imported model in the "Transformation" panel located on the right, ensuring measurements are in meters.

Step 8: Set the top view by clicking on the "Z" axis.

Step 9: Select the wall modeling tool: on the top left, click on the cube icon and choose the "Box" tool.

Step 10: A cube will be generated; utilize this as a wall. Adjust the thickness by clicking on the purple sphere and dragging it downwards. Align the thickness to be nearly the same as the imported model.

Step 11: Position the wall in its designated place in the layout using the green arrow.

Step 12: Employ the mouse wheel to zoom in, and the right mouse button to maneuver the view for clearer visualization of the wall being worked on.

Step 13: Extend the wall by clicking and dragging the purple sphere sideways. Set the correct length to correspond with the layout.

Step 14: Set the side view by selecting the "Y" axis and adjust the height of the wall by dragging the purple sphere downwards. Alternatively, input the desired height by clicking on the purple sphere.

Step 15: Switch the camera view to the "Z" axis. Shift the wall with the red arrow to align it with the wall in the layout.

Step 16: Duplicate this wall using the keyboard shortcut Command + C and Command + V. Adjust the duplicated wall with the green arrow, modifying its length if necessary, and place it in the correct position.

Step 17: Replicate the wall again using the keyboard shortcuts Command + C and Command + V, and rotate it using the blue line. Holding down the left mouse key enables rotation of the wall at a right angle.

Step 18: Resize the rotated wall and position it according to the layout.

Step 19: Repeat the process for all walls required in the layout.

Step 20: Construct the floor; select the "Plane" shape located in the bottom left corner. Adjust its size similar to the walls, fit it to the layout, and remove the imported model (delete layout).

Step 21: Upon completion of your project, export it by clicking on the sandwich icon in the upper left corner, then selecting "Export". Save the project as OBJ or FBX format.

Enjoy bringing your designs to life.
Happy designing!
