section plane advice
section plane advice
(OP)
I am old time autocad user. More recently, Solidworks, Inventor user and now forced back onto AutoCad 2012.
Sections are so easy in the 3D packages. Why so hard in Acad?
I can never predict the outcome of the section view. Why?
Trying to get the section to lay horizontal and to look down (-Z)so i turned all layers off except a section layer. Drew a HORIZONTAL line from 0,0 and used SECTIONPLANE command picking both ends of the line. The result is a VERTICAL plane with the line bisecting it horizontally. (incorrect) So, i created a VERTICAL line from 0,0 and use the SECTIONPLANE command picking both ends of the line. The result is a VERTICAL plane with the line bisecting it vertically.(also incorrect)
I tried changing the direction of the UCS in order to rotate the Z axis in case that has something to do with the plane creation.
Does anyone see the problem here? I am un-able to get a flat plane that i can position where i need it.
Can you tell me what i am missing????????????????

RE: section plane advice
When you create the plane it is based on the currect UCS, so if you're looking down (-Z view, as you say) the cut plane is along the line you drew, but through that line in the Z plane. To get the view you want, flip to the front UCS, and then use sectionplane. (If it is looking the wrong direction, highlight the plane, and use the toggles to flip it.) When you go back to the World plan view, should be what you're looking for.
Doubleclick on the sectionplane to turn the view off or on.
Also, when going to create it, you can use orthographic views to do so, which presets the ucs to match.

I shouldn't have to though, and i would appreciate hearing from someone who can tell me how to do this directly.
