FINDING EXCAVATION VOLUMES
Tip #1859 [VOL.LSP] and [VOL.DCL]
This routine finds the volume of a closed polyline. You supply the depth in the dialog box along with the height and rotation of the text. The current text style is used by default. The polyline must be drawn in decimal (metric) units for metric volumes and engineering units for cubic feet volumes. You can also add volumes for multiple closed polylines.

ADD OR SUBTRACT DIMENSIONS
Tip #1860 [TXTCALC.LSP]
This command, Txtcalc, lets you perform addition and subtraction with AutoCAD text and dimension entities.The command sequence is similar to that of AutoCAD s Area command. When you type in the command, it shows the current total as 0.0 and then asks you to choose the mode (Add or Subtract). Both options prompt you to Select objects. You can select multiple objects at once. The program performs the selected arithmetic operation on the selected entities and shows the new current total. You can continue with the desired option, or type X to show the grand total and exit the program. This program is very useful, especially with dimension objects. It takes care of both default and overridden dimension text.

JOINING TWO LINES
Tip #1865 [SQR.LSP]
This AutoLISP routine sets the Chamfer command s radii to zero so you can join two lines or polylines at their extended junction an old AutoCAD trick that SQR.LSP automates. The routine joins and traps overlapping lines at their existing junction. It also records and politely resets the radii to their initial values before it ends.

Import 3D points from Excel

import-3D-poly.lsp imports x,y,z coordinates from Excel spreadsheet and draws polyline.
Related CAD Tips

Two readers want to import Excel spreadsheet data into AutoCAD. David Rodrigues wants to bring a DOS text file saved from an Excel spreadsheet into AutoCAD. John Kuenzle of Waukesha, Wisconsin, needs to create 3D polylines from x,y,z coordinates stored in an Excel spreadsheet. IMPORT-3D-POLY.LSP takes a set of x,y,z coordinates from a comma-delimited text file and creates a 3D polyline. A comma-delimited text file is a file type you can save directly from an Excel spreadsheet. Figure 1 shows a sample Excel spreadsheet, and figure 2 shows the corresponding comma-delimited text file. The result of running IMPORT-3D-POLY.LSP appears in figure 3. More than a thousand 3D points went into creating this 3D polyline in the form of a helical coil.

HOW TO USE IMPORT-3D-POLY.LSP
Download the file from the Get the Code section and save it in the AutoCAD support directory. From the AutoCAD tools menu, choose Load Applications, or enter Appload at the AutoCAD Command prompt. In the Load/Unload Applications dialog box, select the IMPORT-3D-POLY.LSP file from the support directory where you installed it, then click Close. After you load the program, AutoCAD prompts you to enter PL3 to start.

IMPORT-3D-POLY.LSP displays the 3D Points File dialog box shown in figure 4, where you can locate the text file that contains the required points. No further user interaction is required. The 3D polyline is drawn on the current layer.
