how can I create a full floor plan with multiple rooms in roomle using meazor scans (More than one room)

I have received the meazor and started to work with it.
I want to use it with Roomle as per the collaboration but struggle to create a floor plan for several rooms.
If I do it straight from Roomle, I can only import one room , every new scan creates a new room.
In addition it creates additional walls and it’s difficult to create the image of the room.
If I create it in the meazor app, I cannot find a way to import it into roomie.
How can I create a full floor plan to import into roomle and in which format can I import it into roomie?
I searched on the web but could not find a way to do it
Can anyone help me and provide me a how to do this?
I bought meazor as we need to plan our move and we were planning to use roomie of that so we can fit our furniture in the new place.
Many thanks for a quick help, I am only in our new place until tomorrow and would like to do the measurements so we can do the planning
Many thanks for your help in advance, very much appreciated

How to Import webpage with only the data I need?

I'm new to google sheets and trying to import data from a website to my spreadsheet. The website URL is
https://sagarin.usatoday.com/2023-2/college-basketball-team-ratings-2022-23
I've managed to import some data, but it's not in a format I can use. I want to import the Team name and the 5 power rankings for each team, so I can add the 5 rankings together and come up with a total. When I managed to import the data it includes the team's win lose record in the same cell as the power ranking, which makes it unusable because I can't simply add the power rankings.
Below is the function I'm using to import the data
=IMPORTXML("https://sagarin.usatoday.com/2023-2/college-basketball-team-ratings-2022-23/","/html/body/div/div/div/div/div/div/pre/font/font/font/font")
Any idea how I can get just the team names and the 5 separate power rankings associated with each team?
I've tried numerous times with different functions, but the following is the closest I've come to getting what I want. I only wanted the team names and the 5 power rankings associated with each team. What I got was team names and power rankings, but it also included numbers for win loses and other stats in the same cells, which I don't want.
=IMPORTXML("https://sagarin.usatoday.com/2023-2/college-basketball-team-ratings-2022-23/","/html/body/div/div/div/div/div/div/pre/font/font/font/font")

Import large number of data using CSV/XLS

I have a import functionality in that I upload CSV/XLS file to import a data. I have a 30000 records (CSV) file.(size : 3.4 MB).
This file will take 40 to 50 MIN. to import a data.
As per each record I stored data into 3 tables.
I want to reduce that time to importing a data.
What should I do please help me
Thanks In Advance
I'm going to assume that you are using tables in a database. Importing 3.4 MB shouldn't take that long to import. In on one of my recent projects, I had to import and parse 100MB+ of dictionary files and it only took a minute (python based).
The time really depends on the code that you have written. Although there are some things to look for that will help reduce the import time.
The first is don't print any values in loops. It generally uses up a good amount of time in any language.
Also only open the database once, no need to close it when your in the same function or problem space.
Use the executemany functionality when it is available. When you are ready to commit all of the changes then commit them all at once.
It would also be nice to see how you structured your import function, then I might be able to provide more details.

Black Scholes options pricing

I am investigating how involved creating a very simple options trading platform will be(not for profit but for learning purposed). Can someone please explain the process flow of how Black Scholes option pricing is used within trading platforms, the below is my understanding please correct me if i am mistaken:
1) in memory prices of options derived from Black Scholes formula.
2) an incoming buy order for an option in FIX protocol format.
3) trading platform compares the price of buy order with the price derived from Black Scholes and decides to buy accordingly.
please correct me if i am mistaken anywhere thanks in advance
1) in memory prices of options derived from Black Scholes formula.
That is the job of the user application, Quickfix will not help in any matter regarding this.
2) an incoming buy order for an option in FIX protocol format.
You take the message, parse it and store the rwquired information for yourself.
3) trading platform compares the price of buy order with the price derived from Black Scholes and decides to buy accordingly.
This again is the job of the user application. Inforamtion collected from Step 2 will help you in this.
FIX is a message format for communicating, which should be kept away from your programming logic. Else it will slow down the messaging unnecessarily for no apparent gain.

What do I Need to Develop a Game for the XBOX 360

I will devloping a game using the XNA Studio. The game will not be comercial this is just a freeware game that people will be able to download from the internet. if the game will be freeware do I need to pay money?
Well I suggest you have a look at the XNA Express using C#. You will need to pay $99AUD (Don't know the USD price) to get access to loading the game onto your Xbox. However you can't sell it at all, I believe you can put the source up so that other XNA peepz can play your game though.
If you want to make an actual arcade game you need the real SDK which costs a wee bit of money and comes preloaded on an apple powermac :D.
EDIT:
I stand pleasantly corrected by #JohnRudy. It appears microsoft decided that people might want to get compensation or at least some playtime out of their arcade games. I'm glad they've removed the draconian restrictions on getting your game into the arcade.
So bottom line is: for Xbox 360, no you cannot create a freeware game that is distributed via XBL. You can release the source and others can download and run it on the Xbox, but it will cost both you and the end user money since you would both need a Creators Club membership.
For the PC though you are free to develop and distribute as you wish.
