Transdimensional engineering, (TV: The Robots of Death [+]Loading...["The Robots of Death (TV story)"]) or simply dimensional engineering, (TV: Death in Heaven [+]Loading...["Death in Heaven (TV story)"]) was the technology of creating dimensionally transcendental objects, which the Fourth Doctor proclaimed a "key Time Lord discovery". It was used to make TARDISes bigger on the inside. (TV: The Robots of Death [+]Loading...["The Robots of Death (TV story)"])
Transdimensional engineering could also be wielded to create portals between dimensions, bridging universes together. (AUDIO: Palindrome [+]Loading...["Palindrome (audio story)"])
Principles[[edit]]
While on the planet Desolation, the Thirteenth Doctor claimed that the ability to engineer dimensions was beyond human comprehension. (TV: The Ghost Monument [+]Loading...["The Ghost Monument (TV story)"])
However, the Fourth Doctor had once attempted to demonstrate the principles of transdimensional engineering to Leela, by using two boxes of different size. He placed the larger box on the TARDIS console, and then walked to stand next to Leela and asked which one was bigger, which was pointed out by Leela, to which the Doctor stated it was smaller which was because of the distance. The Doctor said that if the large box was kept away at that distance, and had it nearby the larger box would fit inside the smaller box. Leela called that "silly," much to the Doctor's annoyance.

One account suggested that the First Doctor had been able to make his TARDIS bigger on the inside than on the outside was because the Ship had allowed him to personally observe the dimensions and multi-dimensions which all "existed together in one place with all the infinite others". From this enlightened point of view, physical size in one particular dimension became simply irrelevant. (PROSE: The Equations of Dr Who [+]Loading...["The Equations of Dr Who (short story)"])
History[[edit]]
Dimensional engineering was perfected by the people of Gallifrey in Rassilon's days. A temporally-displaced Eleventh Doctor, under the alias of the Other, bore witness to the "fitting" of huge interior dimensions into a Type 1 TARDIS, against which the sentient timeship was trying to rebel.

The War Chief, a High Councilmember-turned-Renegade Time Lord, (PROSE: The Legacy of Gallifrey [+]Loading...["The Legacy of Gallifrey (short story)"]) taught the War Lords how to construct dimensionally-transcendetal timeships known as SIDRATs. The scale and configuration of their interior dimensions could be altered from the outside by simply sliding cursors on the War Lords' central control panels. (TV: The War Games [+]Loading...["The War Games (TV story)"])
Shortly before the Dalek Civil War, the Dalek Emperor's Daleks constructed Dalek time machines which displayed dimensional transcendentalism similar to the Doctor's TARDIS's. (TV: The Chase [+]Loading...["The Chase (TV story)"], The Evil of the Daleks [+]Loading...["The Evil of the Daleks (TV story)"]) However, after the Last Great Time War, the Cult of Skaro still described the technology which had permitted them to conceal an entire Dalek army in their Void Ship, namely the stolen Gallifreyan prison ship dubbed the Genesis Ark, "Time Lord science". (TV: Doomsday [+]Loading...["Doomsday (TV story)"]) At any rate, Mawdryn's people, who sought to emulate the Time Lords, also employed such techniques for their transmat capsules.

In a parallel world where the Thals and Kaleds lived in peace, Davros and his wife Charn were transdimensional engineers. Together, they developed a portal into the multiverse, the work of many long years. (AUDIO: Palindrome [+]Loading...["Palindrome (audio story)"])
The Ux, who were capable of altering the physical world with a thought, were known to the Thirteenth Doctor through hearsay as "faith-driven dimensional engineers". She deduced that they had used this ability to build Tzim-Sha his shrine on the planet Ranskoor Av Kolos. The Ux later proved familiar with dimensional transcendentalism.

When Missy settled down the 3W Institute inside St Paul's Cathedral, with a group of 91 Cybermen, the Twelfth Doctor explained that nobody noticed thanks to "dimensional engineering — one space folded inside another". (TV: Death in Heaven [+]Loading...["Death in Heaven (TV story)"])
Some humans were able to understand the concept, such as Rory Williams (TV: The Vampires of Venice [+]Loading...["The Vampires of Venice (TV story)"]) and Nikola Tesla, though in contrast, Thomas Edison was clueless.
