While Stripe doesn't support monthly donations, you can still become a sponsor! Simply make a one-time donation equivalent to 12 months of support, and you'll gain access to the corresponding sponsoring tier. It's an easy and flexible way to contribute.

If you are not sure or not able to commit to a regular donation, but still want to help the project, you can do a one-time donation, of any amount.

Choose freely the amount you wish to donate one time only.

You can support FreeCAD by sponsoring it as an individual or organization through various platforms. Sponsorship provides a steady income for developers, allowing the FPA to plan ahead and enabling greater investment in FreeCAD. To encourage sponsorship, we offer different tiers, and unless you choose to remain anonymous, your name or company logo will be featured on our website accordingly.

from 1 USD / 1 EUR per month. You will not have your name displayed here, but you will have helped the project a lot anyway. Together, normal sponsors maintain the project on its feet as much as the bigger sponsors.

from 25 USD / 25 EUR per month. Your name or company name is displayed on this page.

from 100 USD / 100 EUR per month. Your name or company name is displayed on this page, with a link to your website, and a one-line description text.

from 200 USD / 200 EUR per month. Your name or company name and logo displayed on this page, with a link to your website and a custom description text. Companies that have helped FreeCAD early on also appear under Gold sponsors.

Instead of donating each month, you might find it more comfortable to make a one-time donation that, when divided by twelve, would give you right to enter a sponsoring tier. Don't hesitate to do so!

Choose freely the amount you wish to donate each month.

Please inform your forum name or twitter handle as a notein your transfer, or reach to us, so we can give you proper credits!

Descriere

Instrumentul Radius Dimension adaugă o dimensiune a unei raze la o View. Cota/dimensiunea poate fi aplicată la orice margine în desenul care este un cerc sau un arc de cerc.

The TechDraw RadiusDimension tool adds a radius dimension to a View. The dimension may be applied to any edge which is a circle or circular arc.

Measuring a circle, indicating the radius

Cum se folosește

  1. Select a circle or circular arc. The geometry may be selected in the 3D view or in the drawing. Note some arcs which appear to be circular are actually ellipses or B-splines. You cannot make a radius dimension in these cases.
  2. If you have selected geometry in the 3D view: add the correct TechDraw View to the selection by selecting it in the Tree view.
  3. There are several ways to invoke the tool:
    • introduced in 1.0: If the Dimensioning tools preference is set to Single tool (default): press the down arrow to the right of the button and select the Insert Radius Dimension option from the dropdown.
    • If this preference has a different value (and in 0.21 and below): press the Insert Radius Dimension button.
    • Select the TechDraw → Dimensions → Insert Radius Dimension option from the menu.
  4. A dimension is added to the View.
  5. The dimension may be dragged to the desired position.
  6. If needed, add tolerances as described on this page.

Display 3D measurement

See TechDraw LengthDimension.

Change properties

To change the properties of a dimension object either double-click it in the drawing or in the Tree view. This will open the Dimension dialog.

Limitations

Dimension objects are vulnerable to the "topological naming problem". See TechDraw LengthDimension.

Notes

See TechDraw LengthDimension.

Proprietăți

See TechDraw LengthDimension.

Script

Cotele tip rază pot fi adăugate la Pages utilizând Python.

The Radius Dimension tool can be used in macros and from the Python console by using the following functions: 

dim1 = FreeCAD.ActiveDocument.addObject("TechDraw::DrawViewDimension", "Dimension")
dim1.Type = "Radius"
dim1.References2D=[(view1, "Edge1")]
page.addView(dim1)
