Convert Amapi 3D modeling data to ISO-10303 STEP product data.

We have found one software suitable in our database for this conversion.

Amapi 3D format (.a3d) is somewhat old and the program itself is discontinued for years so you will not find many current programs that still support this particular file type.

However, some dedicated converters like 3D Object Converter should still support it and allow you to convert it to something else, for example to the STEP product data format (.stp, .step).

The table with program actions contains information about what each program is capable of doing with their files. This may be a good pointer for further searches for certain file conversions and help you find the converter you are looking for if our search result is insufficient for you. However, it is far from perfect and may sometimes show results which are not really usable because of the nature of the software handles the files. So a conversion that appears as possible, just because of matched actions, may in fact not be possible.
