Rotation Center Indicator color selection...

NOT even close to a big deal; I have been hesitant to post about it.

I have found that the "Rotation Center" indicator color and transparency cannot be set or saved via the Edit|Preferences|Display|Navigation dialog. Clicking the "sample" box opens a color selection dialog (color only, no transparency)--however selecting a new color does nothing, the color of neither the sample or the working indicator is changed.

I have vision issues from lifelong diabetes and would like it to much more "in my face!"

Edit|Preferences|Display|Navigation dialog--and the color selection dialog

AFAIK it has not worked since introduced--currently I am running b39100(git) on Linux Mint v22/Mate.

I created a similar post on the FC "issues" forum.

I tried it on Win 10 Pro--does not work there either....

Has anyone else experienced this?

I just released Introduction to FreeCAD 1.0 Part #5 - In this video we add a spreadsheet to the existing model to demonstrate how we can drive the model from a spreadsheet. It makes modifying parametric models very easy.

Curves workbench buggy

Hi,

I needed to cut out some rotating latch out of a cylinder, so I thought why not use the Curves workbench. So I created a simple cylinder

https://preview.redd.it/qicvtsjmtwzd1.png?width=803&format=png&auto=webp&s=3f0619ca784a76bba49c1daef46fd1b219454d54

Then created a sketch on the surface

https://preview.redd.it/s6d2z4astwzd1.png?width=1680&format=png&auto=webp&s=1a42acd1e3d96b61105f86a10005a483caf5d90c

Times four

Which successfully generated the following 3d geometry with thickness -3mm

https://preview.redd.it/9ym4pmyxtwzd1.png?width=989&format=png&auto=webp&s=674bb8c1ac5bba5e7542c7a891777bcccb14318a

But then with a boolean cut, it only seems to cut the first and fourth small piece out successfully, leaving the second and third still filled.

Good

Bad

Does anyone have experience with this issue? Am I doing something wrong here?

Increase Assembly 4 measure tool font size

I'm running FreeCad on a Mac using a 4k display. My Mac's display settings are set so that the text size imitates how it would appear on a 2560 x 1440 display, and looks fine in all other apps and the rest of FreeCad. However, when I use the measure tool that comes with Assembly 4 and have the option checked to add the measure to the 3D view, the font size of the text that's shown in the 3D view label is incredibly small. Is there anyway to increase the size of the font used to display the measure? I'm running v1.0.0RC2, and I don't want to use the new measure tool as it regularly crashes FreeCad. Thanks

Align edge of body to an edge of another body

Hi,

New guy here. I would like to design a cabinet that goes under the roof. This is how it looks like currently. I used A2Plus to align the bodies that are in different files.

(almost) full cabinet

What I cannot find, is how can I raise the inside line of the back panel to meet the angled part:

Can somebody please help me out?

thx,

Creating an inverse piece

We're making something for holding jewellery and printing it in two parts, pictured is the base ofur first part which we want to mate with the second piece (main base)

It is made up of multiple pads

What would the best way be to get an inverted piece ? (Our first thought was a clone of the whole first structure lol)

Hire someone to both implement 3d printable design and afford me the opportunity to learn form your process

I have a desire to expand my FreeCAD and 3d printing design skills. To that end I have a desire to (over) design a nametag that will be 3d printed on a bambu printer with multiple colors and have cavities where I'll pause the print to add a metal plate to magnetically secure it to clothing. The name tag is for a class I'm involved with.

I've made several false starts, but get stuck and just cannot make forward progress in my model attempt.

I'd like the design to make good use of parameters, or at least be a design accessible to me to tweak, as I'll want to customize the person's name and I still have more experimentation I'll need to do to create a quality print.

For example my goal is to stay under 2mm thick and the metal plate needs 1.1mm and in my tests, some color filaments need multiple layers for the color to look crisp due to semi-translucent nature.

The final 3d print will also need to have multiple overlapping bodies for the different filament colors when I place an export into the slicer.

There is a 4 color compass logo with state of Florida outline, I only have as an image, that will need reinterpreted as 4 bodies so I can select colors.

There is two lines of text that will vary between nametags. (Shape from Text)

If I need to take this request elsewhere, let me know.

I'm sure there is more you need to know. LMK what else you need to eval if you're interested and I'll comment.

I'm happy to compensate someone for their time creating this but I also want to grow my FreeCAD skills and understand your process.

Why can't I sketch on a pad in CATIA?

So I made a circular looking table and I wanted to sketch on a pad. My guess on why I couldn't use the sketch function on the pad is because of the shape, but I'm not sure. Does anyone have the answer?

*the red thing is the pad I was talking about

a hole in a padded circle - an unexpectedly difficult problem

Hi,

I'm having an unexpectedly difficult problem with shape presented on the screenshots. Let's go step by step.

1. First I'm creating two surfaces by padding the side surface.

2. Then I'm creating a cirle in a place where the surfaces connect.

3. I'm getting what I want except the bottom part.

4. I'm using \"connect objects\" from Part workbench and the part looks great.

5. Now I want to create a hole running through all elements.

6. ... and that's the result.

I guess the problem starts when I use the "connect parts" option. After applying it I'm getting dialog about copying an object, etc.

Please help! Thanks.

"Result has multiple Solids" when it doesn't

Hi All,

I'm very very new to FreeCAD so maybe I'm missing something very obvious. I'm working in part design and I currently have a cylinder that I'm trying to add a shorter wider cylinder to. The first cylinder was made by a sketch of a circle that I then padded, it's radius is 10mm and the height is 100mm. I'm trying to add another cylinder to the middle of it that's shorter but wider. At the halfway point (50mm), I'm adding a cylinder that is 12mm radius and 10mm in height. I did this by putting a datum plane at 50mm and putting a sketch there. When I trying to pad the second cylinder I get the error message "Result has multiple Solids, this is not currently supported." This is just clearly not the case.

Disclaimer: I have other pads/lofts/pockets along and on the ends of the cylinder but those were all fine before I add this other cylinder onto the main cylinder so I don't see how those could be a problem.

RC2 Sketch Edit

This post is to say thanks to the team working on FreeCAD.

The previous versions were kinda difficult to determine which parts of a sketch were left open or unconstrained. Try to extrude and it just errors out. In RC2, it made these openings SOOOOOO easy to find (the white points). Thanks!

New to FreeCAD - Best Way to Create a Stubby Leaf Blower Nozzle

I am new to FreeCAD and I am trying to figure out the most efficient way to create a stubby nozzle for my Atlas blower. I started with a basic sketch of the inside dimensions for where it attaches to the blower and then added 2mm to create the outer sketch. Then I extruded the outer sketch and used the hole option with the inner sketch . My dimensions are not perfect so will need to be tweaked but that is not the main issue. The are where the locking tab has some angles and I'm not sure how that would work. Is there a more efficient way to create this model than what I am trying to do?

Edit: I'm using FreeCAD 1.0 if that matters.

Task Failed Successfully

Hi there lads and lasses.

A friend of mine shared a task in CAD class with me today. A very rudimentary task.

I thought of giving it a slightly different approach.

Task:
Make a base plate 10 mm thick. 100x100mm.
Make a hole in the middle of the plate that fits one M6x8 screw.
Make sure the screw cannot fall out when it's flipped over.

Task is deliberately a bit vague to see how people solve it.
I made it as shown in the picture below. And yes, the screw can stay put if it's twisted inside the pocket as that locks it in place.

Overcomplicated? Absolutely! does it fulfil the task at hand? Absolutely!

I thought of sharing this and to hear with you guys what tasks you had in class/work/hobby that you solved differently than expected. Was the alternative solution a success or a failure? Was it made deliberately incorrect?

how do I cut this model into two pieces

I've got this model that I'd like to cut into two pieces that I'll print and reassemble. How would I go about making a cut along something like the lines indicated so I can get two independent objects to work with?

I am trying to 'pocket' the slots so one end slopes to the other. I just placed a brown cube in my picture for demonstration. I've been trying to figure this out but I couldn't get booleaning something together nor control the pocketing to work. Any ideas on how to do? Thanks!
