Hello there. It's been a looong time, but I had (and still have) to study.
I was able to sneak some time for the 5Point star fort and was able to almost finish it and paint it.

Here we can see Helen at the corner of the trench of Point 1, with the external fort at her left and the bridge and drawabar bridge just behind her. Notice the cylindrical garites at the three main corners of each bastion.
I might make a rough model of a cannon to place one on each position available. This fort is designed to have at most 40 cannons (8 per bastion).
Also, notice that the top of the parapet is slightly tilted so that any shooter can place his gun over the top and rest it there while aiming.
The parapets on the inner side are 2 meters tall, and tou gould need a stepping stone to get your head and shoulders to effectively position your gun.

Here's a top view of the 5 point star fort, almost fully colored. Point 1 is the one at the right. There's an advanced fortification in front of the door side, to protect the door. However, this fortification shouldn't house cannons, so they can't be turned on the main Fort should the advanced fortification fall to the enemy.

New Project, Castle of Burgos
Hi, I've found another proyect for 3D modelling.
This is the Castle of Burgos (Spanish castle at the Spanish city of Burgos) as it was when the French (Napoleonic troops) had Spain invaded for 5 years.
During this time, the french mappers and topographers took their measures and eventually drew the map:

I'm going to cross-reference the roads shown there with the heightmap of today to make the model:

Hello again.
I've found a bigger map of the fortification and it includes the surrounding city and roads, the river and a hornwerk plus ravelin to the North.

Now it's going to be easier to cross-reference the heightmap.
Also, I've found some images of a model of the castle in the period 1808-1812, that will help in the modeling of the original castle ("Donjon" in the map), here they are:

I couldn't find any view of the model from West to East.
I could make a heightmap with the help of Google Earth:

I feel like I should tell a bit about the history of this fortification.
Before the French invasion of Spain, it didn't have much strategic value, as it was in the center of Spain.
It was built in 884 during the Reconquest of the Spanish Christian Kingdoms, and it was ampliated by the following castellans.
Between at least 1042 and 1277 it served as jail of noblemen, and from 1252 to 1284 and 1390 to 1454 served as palace. (Yes, I know the periods as jail and as palace are overlapped, but one tower could serve as jail while the rest of the castle served as palace).
It saw use as stronghold in the civil war of 1474-76.
In the XVI century it was used as artillery academy and gunpowder factory.
In 1736 there was a fire that burnt the wooden decorations of the palace, made on 1252.
So, before the French invasion, it was mainly a late-medieval castle, that's the part that's recognisable nowadays.
Then came the Napoleonic invaders in 1808 and they took the castle and the city, and held it for 5 years.
Because the French were invaders, they needed to secure every strategic position they could find, so the castle and the hill was again a strategic spot in the surrounding plain.
They brought the defenses up to date in those years and they built a hornwerk and ravelin on the hill of San Miguel.
From september to october of 1812 they went through a siege by Arthur Wellesley (later known as Duke of Wellington), where the siegers (Anglo-Portuguese) went through a great number of casualties, while the sieged (French) only lost a fifth of their numbers.
Later, in june 13, 1813 the French retired from the fort, and they made it explode to avoid leaving any equipment or documents usable to the enemy.
Today what remains is part of the medieval castle.
Hi, I need a KiloByte of help please. Does anybody know how to make heightmaps from the black-to-white gradient on Sketchup?
I've already tried with the Bitmap to Mesh extension for SketchUp but it gives out an error when I input the bmp file.

Oh, solved, although it has blocked doing something.
Anyway, there goes the heigtmap:

Note: Yeah, I know that the terrain's Z axis is too big compared to its X axis.
It should look more like this:

For anybody guessing, I'm following this tutorial here on youtube: https://www.youtube.com/watch?v=Qd2dqe3v7nU
This looks like an interesting project.
I did my tutorial on how I make height maps from drawn contours here:
https://www.cartographersguild.com/s...ad.php?t=33666
I think you have solved it now but I dont know how to get a greyscale gradient into sketchup.
