Hello. I hope you are reading this in good health.

A cinder block fell into the acequia (irrigation ditch) which provides irrigation water for our place. The current thus diverted undercut the earth bank a little; it's not likely to collapse now, but I can imagine it will be prone to further erosion now.

I thought of creating an eddy just at the upstream end of the undercut to slow the water and cause it to drop sediment into the undercut.

Can one create an obstruction that creates an eddy that reliably deposits sediment?

How does one balance the interaction of angle to the current and rate of flow?

Is it possible to err and create an eddy that cause erosion rather than deposition?

Thank you.

Hello. I hope you are in a peaceful mind.

I am using QGIS 3.32.3-Lima on MacBook Air running OS 15.6.1. I have a shapefile layer which has all the U.S. states as individual features. I would like to split the California feature along a line of latitude, without splitting or otherwise affecting any other state feature. It doesn't matter whether the California feature is split within the current layer or is split to create two new layers.

Thank you.

Hello. I hope you are doing all right today.

I have a slab of wood about 4.5 feet long by about 2.5 feet wide, 5 inches thick. I want to put stake legs on it and use it as a planing bench. Since I will be applying significant force lengthwise along the bench I think the legs should have some raked angle. Since it is narrow enough that it might be tippy, the legs should have some splay.

But the thing is quite heavy for its size, so I think the rake and splay should be tempered - that is, reduced enough that the legs are mostly transferring force downward.

I know how to set legs to meet prescribed rake and splay. But how does one figure out the prescription for the rake and splay themself?

Thank you.

Hello reddit people. I hope you are doing all right today.

I have not yet downloaded FreeCAD. I would like to know whether it will work to draw out leg angles on a small bench where each leg is splayed 7º from the vertical plane through the center-line of the bench, and raked 14º from the vertical plane perpendicular to the center-line of the bench.

I'd like to draw the resultant legs and also find the "sight lines" for each leg. My understanding is that a sight line is the angle from which the eye sees the leg as 90º to (straight down from) the plane of the bench underside.

Can FreeCAD do this? If yes, is it real hard to do it?

Thank you.

Hi everybody. I hope you are doing all right today.

Does GIMP have ability to figure out 3D relationships, like the old free Sketchup?

I'm going to try drawing out the angles for the legs on a small bench. These angles are measured relative to a line perpendicular to (straight down from) the bottom surface of the bench; that is, they are angles away from that perpendicular line.

It's complex.

The side-ways angle, called the angle of splay, is 7º. The angle along the length of the bench, called the rake, is 14º.

Is there a way to plug numbers like these into GIMP and have it draw the resulting lines?

Thank you.

Hello. I hope you are reading this in good health.

I am using QGIS 3.32.x (Lima) on a MacBook Air running OS 15.6.1.

I have a project in which I want to automate assigning new clients to their nearest district.

Layers in place are

District_centers
New_clients_May_Geoaddresses

These are .csv layers.

District_centers has column A - District 3-digit ID number; column B latitude of district center; column C longitude of district center.

New_clients_May_Geoaddresses relevant columns are column A with unique ID number for each client; column B client's name; column D, the district to which the client will be assigned (at this point no data in column D); column N the latitude of client's address; column O the longitude of client's address.

I want a process by which

1. each new client's latitude-longitude address position is compared to the latitude-longitude position of each district center;

2. the district center which is closest to the client's location is identified;

3. the district ID number is pasted into the client's record (row) in column D.

I appreciate insight into how this may be done. Thank you.

Hello. I hope you are well today.

I want to download all the U.S. incorporated places with their names and coordinate positions (center point) or polygons.

Can I do this from OpenStreetMap? Is there another place to get the data?

Thank you.

Hello. I hope you are doing well today.

What would be an effective way to put legs or a base on this wood slab to make a rustic, sturdy workbench?

It's about 4 feet long.

Hello. I hope you are in good mind and sound health.

We had to cut down an IKEA Sektion base cabinet from 15" to 12.75", so the standard Maximera drawers will not fit. We would like to make drawers ourselves.

I think there are two ways to do this.

(1) Make drawer fronts and backs that we will attach to the Maximera drawer sides. Then we could use the Blum slides without complexification. (I think the bottom will be easy.)

The question with method #1 is how the home-made drawer front and back will fasten to the standard Maximera sides. I have not looked at this problem in detail yet, so I'm not sure how difficult it might be. Maybe it's simple.

(2) We make the entire drawer body ourselves - front, back, sides, and bottom. This way, the fastening together of parts is however we decide - probably back and front glued into rabbets in the sides, and bottom slid into a rabbet on both sides.

Big challenge with method #2 is figuring out how the home-made DIY drawers will interact with the Blum drawer slides.

What do you think?

Thank you.
