What is HTP file?

The HTP file has been categorized as 3D Image Files. The author of this format is Autodesk, Inc.. 3D Image Files consists of 622 similar files. Autodesk Slope Template Definition is most often found on 1 operating systems. The file will work on Windows systems, unfortunately not on others.

How to open HTP file?

The most common problem when using Autodesk Slope Template Definition is that a specific HTP is not associated with the program. This is manifested by the fact that HTP files open in unusual applications or do not have an assigned program. How to solve such a problem?

The first thing you should do is just "doubleclick" on the HTP file icon you want to open. If the operating system has an appropriate application to support it and there is also an association between the file and the program, the file should be opened.

Step 1. Install AutoCAD Civil

An often overlooked issue is to make sure that AutoCAD Civil is installed on the computer. This can be achieved by typing AutoCAD Civil into the operating system search engine. If we do not have this program, it is worth installing it, as it will help you automatically associate the file HTP with AutoCAD Civil. Below is a list of programs that support the file HTP.

Programs to open HTP file

Remember to download programs supporting HTP files only from verified and safe sources. We suggest using the websites of software developers.

Step 2. Create association of AutoCAD Civil with HTP files

If, despite the installed application, the HTP file does not start in the AutoCAD Civil application, you must create a file association. It is most convenient to call the context menu with the right mouse button and select Properties. The displayed window will contain information about the program that supports this type of file. Using the "Change" button we can set the program to handle this type. If there is no software on the list, simply select "Browse" and manually select the directory where the application is installed. The "always use the selected program ..." field will set the AutoCAD Civil application as the default for handling the HTP file.

Step 3. Update AutoCAD Civil to the latest version

If, however, after binding AutoCAD Civil with Autodesk Slope Template Definition there were still problems, you should update the program to the latest version.

Step 4. Check for the following problems with the HTP file

Of course, it may happen that despite the above steps, the file still does not work. This could be due to the file itself, the cleanest issues are:

Very often, the file may be size 0 or incomplete. Usually this applies to HTP files downloaded from the Internet in case the download did not finish properly. The file should be downloaded again, making sure that the process has finished correctly.
The computer may have fallen victim to a computer virus or hacker. A virus scan using an up-to-date antivirus program should fix the problem. Some antivirus vendors also provide free online scanners. The scan should cover the entire computer, not only the HTP file that we want to open. As a result of the scan, sometimes it is not possible to recover HTP files, which are deleted if there is a backup of this file, then after restoring it, it must also be scanned.
This can happen especially when the program is dynamically developed and the structure of the HTP files changes over time. On their websites, developers usually offer free solutions to such problems, e.g. in the form of a conversion program or an older version of the program.
There can be many reasons for the failure. The repair method must be adapted to the type of file and damage. Some programs offer the option of recovering data from damaged HTP files.
The program can also signal the fact of encryption. The encrypted HTP files can be used by the device on which they were encrypted, on any other device it is required to have the appropriate cryptographic key and decrypt the file before its recovery.
Some operating systems do not allow file operations in certain locations, eg in system directories or directly on the system drive. While there is usually no problem reading such a file, it may not be possible to save it. If possible, you can try to move the HTP file to another location.
This problem usually affects more complex files. You may find that another program you are using is preventing you from working with the file. Just close unnecessary programs. If the error persists after closing other programs, wait for a while. However, some background programs may block the HTP file while scanning. If the problem persists, restart the machine.
