Using Joist Span Tables to determine joist size while drawing
SoftPlan Version:
2014

I have enabled the ceiling joist span table option in the system options.  When I press the 'ceiling system' button and draw a joist area, it always frames it with the same height joist that is specified in System Options > Material Dimensions > Ceiling Options.  Therefore, it draws everything, regardless of span, with 2x6 joists.  When I double click the area, it brings up the joist properties and I have to manually select the span table to use.  If it's a large room, once I select a span table, it will say "This span is too far, maximum span is XXX...."   And then I have to manually change the size of the Joists.  Is there a way to link a span table to the Ceiling Joist tool, so that when I draw a joist area, it will take the span, check the table, and draw joists the appropriate height automatically?  When I draw a 20' room it will draw 2x12, a 10' room it will draw 2x6, etc.  I see how to customize the span tables to meet my needs for span criteria, but I can't figure out how to make the software calculate joist size automatically when drawing.  Going back and changing all the joists to the correct size after drawing them all isn't very efficient.

 

Thanks!

Joists

Unfortunately, no. You have to edit each joist set and specify the sizes, span table, and possibly elevation.

Also, if you haven't discovered already, there are Levels that need to be specified. Levels are numbered like Level 1, Level 2, etc. All joists that belong to the same Level will be at the same size and elevation. You have to be careful when using Levels because if you change the size or elevation of a joist set it affects all other joists that belong to that same Level. If you go to Visible Items and select "Show Joist Level" the various Levels will be color coded so you can see what joists belong to the same Level. Unfortunately you can not name the Levels. I've been trying to get SoftPlan to allow for naming levels something like "2x6-16" O.C. @ 9'-1 1/8" but so far that capability hasn't been added. Having numbered Levels requires that you have some method of keeping up with the specifications of each Level. For instance you might keep a running no-print note with information about each Level. Or you could keep a note pad with Level specifications and reference your note pad when assigning Levels. So basically you assign the specifications for a Level to one joist set and then assign that same Level to any other joist sets that would have that same specification. Since Level 1 is assigned by default I will typically draw in all the joists and then start assigning Levels beginning at Level 2 and up. That way I don't accidentally screw up all my Levels by making a change to a new joist set which is set to Level 1.

I understand everything you

I understand everything you said.  Thank you for the info.  Sounds like they need to spend some more time making the joist tool system a little more intuitive and efficient.

Yep

Yep, I would agree with you there. If more people would make suggestions for enhancements perhaps they would make the changes. SoftPlan is pretty good about adding new features but not so much in enhancing existing features if nobody suggests the changes. I would love to be able to spend a day with the development team and go over my list of things I would like to see changed or enhanced. Most of them are very minor but they would make a big difference in productivity and ease of use.
