Design table in assembly
Design table in assembly
(OP)
This question may sound kinda familiar, but it hasn't been answered so please cut me some slack.
Questions about design tables have been posted here, but they have only been shown to change configurations of parts, or change the distances of mates and angles at the ASSEMBLY LEVEL. How do you make it drive a dimension OF THE PART at the ASSEMBLY LEVEL, such as a dimension on a tube.
thread559-142901 is one where I posted an equation, but couldn't do it in a design table.
http:// img380.ima geshack.us /my.php?im age=assemb lydesignta ble7wy.jpg is a screenshot of a simple assembly I will use for this example. If I change the length of the horizontal tubes, it will automagically add the vertical tubes to span the distance. How can I add the length of the tubes in design table? Scott has an example of a design table on his website, but it only changes the configs of a part, not the driving dimensions. Would any of you be willing to look at this assembly and try it?

RE: Design table in assembly
I would create a layout sketch in the assembly for the outside dimensions. Then link the individual part sketches to the layout sketches using sketch relations and "up to" end conditions.

Here is a drawing of a some stairs for a high-school in Fort Worth, TX. We built the stairs, handrail, guardrail, newel-post, literally everything on the first page. It was created in a parametric-modeler, and by changing a few parameters, everything updated, from the flat-pattern of the steps, to the cut-angles of the handrails. That is the reason I want to know if it's even possible to change part dims in a design table at the assembly level.
P.S.
Here is a link to the other design tables I spoke of earlier:

Enhancement request it looks like.
I think Scotts parametric assemblies he did were done with in-context relations. You still drive the assembly parameters from a design table. Not sure how that's any different other than just actually "seeing" the parts dimension. Same end result.
Oh....there is another possible. You can use equations to link part dimensions directly to assembly dimensions. So you would still have to have some layout sketches with dimensions. Then create an equation and select the part dimension and make it equal to the assembly dimension. then place the assembly dimension in your design table.
Personally, I would like to see two things added to Solidworks:
1. The ability to override a part's dimension from an assembly. Nice in that it's does not require you to write anything to the part file itself like in-context relations require.
2. And a library type part option where you can define which dimensions the assembly controls with a prompt to define it upon insert. I think Inventor has something where you can leave an extrusion depth sort of "flexible" and use planes and faces to control the actual length.
