Placing elements on wall

Anonymous — Mon, 18 May 2015 05:54:29 GMT

Hi,

Struggling to place an element on wall[second floor level] like switch , mirror light etc.

Tried several combinations of NewFamilyInstance but nothing led to place elements on wall. They seems to be fall very below the second floor level.

Thanks & Regards

Dear, would you please attach the family file, so that I can try from my side?

try these 2 methods:

FamilyInstance NewFamilyInstance(Reference reference, XYZ location, XYZ referenceDirection, FamilySymbol symbol)
FamilyInstance NewFamilyInstance(Reference reference, Line position, FamilySymbol symbol)

for example:

Wall wall = null;
var references = HostObjectUtils.GetSideFaces(wall, ShellLayerType.Interior);
var reference = references.First();
RevitDoc.Create.NewFamilyInstance(reference, new XYZ(0, 0, 0), new XYZ(0, 0, 1), familySymbol);

Hi,

When I am trying to use this method

doc.Create.NewFamilyInstance(face, location, xrefdir, symbol);

the attached family Mirror Light fixture gets placed at the bottom of the wall and also its elevation property is disabled but when I manually place that family on the wall it fits correctly and and also elevtion property is enabled. and When I place the attached switch family [Switch board] via the above method it places in a surprising way.

screenshots follows:

switch placed via code . Note that elevation is grayed out/disabled

switch placed manually

Thanks & Regards

What about changing the parameter "Schedule Level" to a real level after creating
and then see if the parameter Elevation is editable?

Tried and changed "Schedule Level" to a real level still elevation is grayed out. but when cut and paste the instance created normally then it works perfectly fine.

I don;t know but it should be pretty simple

1. Get the face of the wall.

2. decide the fanily to palce

3. decide its location to lace

4 and then place it

what in the world am I doing wrong.

Thanks & Regards
