 object snaps are modes that allow you to snap to specific points on objects. To snap to the centroid of a closed polyline, you should use the Geometric Center object snap mode. This mode will display an asterisk (*) marker when you move the cursor over the geometric center of a closed polyline or spline.

To use this mode, you can either:

Click on the Object Snap icon in the Status bar and select Geometric Center from the menu.

Type GCE at the command prompt or when prompted for a point and press Enter.

Now you can snap to the centroid of a closed polyline by using Geometric Center object snap.

When creating a path array in AutoCAD, the objects being arrayed typically align with the direction of the path by default. To maintain the original orientation of the objects while following the curved path, you should turn off the "Align items" option.

Select the Object: Choose the object you want to array along the path.

Path Array Command: Use the ARRAYPATH command or go to the Array command and choose Path Array.

Select Path: Select the path (curved line or arc) along which the objects will be arrayed.

Turn Off Align Items: In the Array options, turn off the "Align items" checkbox to ensure that the objects maintain their original orientation.

This will keep the orientation of each object the same as the original, regardless of the curvature of the path.

a block attribute is a tag or label that attaches data to a block. The data can be extracted and displayed in a table. Therefore, the entity in the drawing that is used to put the graphical representation of the room number in the Room No. column in the table is B. Attribute.

According to the AutoCAD for Design and Drafting documents1, the command that should be typed at the command line in order to start creating a line for drawing reference that starts at a defined point and extends to infinity in the designated direction is XLINE2. This command creates a construction line, which is a type of reference line that can help you manage accurate parameters of your drawing2. You can also use point objects as nodes or reference geometry for object snaps and relative offsets3.

The command that you should use is B. Collect Leader1. The collect leader option groups multiple leaders into one multileader object with a common landing line1. This option is useful when you want to create a single label or callout for multiple objects2.

To use this option, you need to select the MLEADER command and then select Collect Leader from the Options menu. Then you can select two or more existing multileaders that have similar properties and press Enter. The selected multileaders will be collected into one multileader object with a common landing line1.

To ensure that all drawing information is visible when plotting from an ISO A3 layout to an ISO A4 sheet size, the correct plot settings need to be applied.

Open the Plot Dialog:

Type PLOT in the command line and press Enter.

Set Plot Area:

In the Plot dialog, set the "Plot Area" to Extents. This ensures that everything within the drawing extents will be included in the plot.

Adjust Plot Scale:

Set the "Plot Scale" to Fit to paper. This option will automatically scale the drawing to fit within the ISO A4 sheet size (297 mm x 210 mm).

Other Settings:

Ensure that the correct printer/plotter and paper size (ISO A4) are selected.

Optionally, check the "Center the plot" option to ensure the drawing is centered on the sheet.

Save Changes:

Click on the "Preview" button to check the output. If everything looks correct, click "OK" to plot the drawing.

The Current prompt should be used to make sure that the edge of the top step is shown in a different linetype, as shown by the dashed line in the exhibit. This way, you can set a different linetype for your current layer before using the OFFSET command4.

You need to ignore layer object property to remove duplicates that have different layer names but are otherwise identical4. You also need to set a tolerance value that is larger than the offset distance between the objects5.
