I&#39;ve been busy getting Xrev Revit API products off the ground... For that step I just nested twice, placing the nested family at the origin point, linked through all the parameters to the host family, and then repeated it. This appeared to get around this revit &quot;bug&quot; not conforming to the true origin.<br /><br />I find this particularly annoying on doors if you want to nest in clearances for disabled access or have a swing greater than 90 degrees...Chrishttp://www.blogger.com/profile/01382602297165554911noreply@blogger.comtag:blogger.com,1999:blog-19080627.post-6780885372128260692011-04-09T10:14:20.109+10:002011-04-09T10:14:20.109+10:00I realize you created this video quite a while ago, but I am trying to generate a parametric crane in Revit and stumbled on your video (thank you!). <br />I am having issues with the very last part where you are placing the final nested family ( I think you called it nest boom body) into the main family. When I try to create a parameter to rotate it, it rotates around the center point of the nested family, which changes depending on the angle of the boom, etc. I&#39;m guessing that solved it by nesting the boom body in anther family where you locked it to the pivot point, but you kind of breezed through that part and I can&#39;t figure out how to constrain it to make the pivot point correct. Any tips would be much appreciated!

Sometimes nesting is a necessary evil in order to simplify parametric control.<br /><br />The family took me about an hour to make the first attempt, but I was using an imported image to trace the various sections so that delayed the process a little.<br /><br />More to come...Chrishttp://www.blogger.com/profile/01382602297165554911noreply@blogger.comtag:blogger.com,1999:blog-19080627.post-3776671948523160862010-07-13T02:17:30.812+10:002010-07-13T02:17:30.812+10:00Interesting family, just curious what the file size is with all the nested families together and how long did that take you?<br /><br />Keep the videos coming!<br /><br />Philip ChanAnonymousnoreply@blogger.com
