Hello, thank you for taking the time to read this. I'm new to CAD overall, and brand-new to FreeCAD.

I'm trying to design a part that's triangular in shape. All verticies are filleted with some radius. The baseline is horizontal. How can I set the height of the part to a specific distance from the baseline to a horizontal line tangent to the upper fillet?

Thanks, again, for your thoughts.

Sorry, should have mentioned that I'm trying to do this in the PartDesign Workbench.

if it is a filley of part design just open the filley and you see the width

Hi Kevin, and welcome! Because you're using Part Design I think you'd set the height in a Sketch. One way is to create and Constrain a Vertical Construction Line Segment from the center of the top fillet arc to the top of the fillet arc. Then apply a Vertical Distance Constraint from the top Endpoint of that Construction Line Segment to the base.

bejant, thanks so much for your guidance. I forgot about construction lines and how they could be used. I'll use your method to see if I can get it to work. I'm having trouble with some of the simplest things (see my latest post), and if I have any further questions, I'll get back to you.

Thanks, again, for your help.
