I am trying to create an arch and I am getting a circle.

Hello,

I am trying to create an arch and I am getting a circle. what am I doing wrong?

the code:  arch = Arc.Create(
new XYZ(item.start[0] * Common.METER_TO_FEET + base_point.X, item.start[1] * Common.METER_TO_FEET + base_point.Y, 0),
new XYZ(item.end[0] * Common.METER_TO_FEET + base_point.X, item.end[1] * Common.METER_TO_FEET + base_point.Y, 0),
new XYZ(item.middle[0] * Common.METER_TO_FEET + base_point.X, item.middle[1] * Common.METER_TO_FEET + base_point.Y, 0));

w = Wall.Create(doc, arch, wall.Id, levelId, Common.WALL_HEIGHT * Common.METER_TO_FEET, 0.0, false, false);

thanks for your help!

you can get both endpoints and set it...

I am sorry, I didn't understand. When I created the Arc, it wasn't supposed to be Arc.Create(end0, end1, pointOnCurve)?

What a, I suppose to do with the GetEndPoint(). I just started to work with Revit, so please be patient with me. 

can you give an actual example? 

[Yien_Chao]

my bad. i think the endpoint cant be set.

but you can create your arc at least with 3 methods

if you dont want a circle, try with : 

Create( XYZ end0, XYZ end1, XYZ pointOnArc

hope that could help

It is exactly what I used

Your first step is to look at the numbers for start/end/middle. No real point answering a question where the most likely error is the numbers you are not providing in the question (other than to say provide the numbers).

I prefer the other two overloads to be honest.

Would also do the conversion from m to ft elsewhere, likelihood is you have two points close together.
