Parametric Profile Family

[MHiermer]

Hello all,

i want to create a rather simple parametric profile familiy, but i ran into some trouble with a diagonal line within. I cant pin it down the right way, one end is always moving off.

As you can see at the picture, the left half should stay on its place, the right half should move with a "Width" parameter. Everything is fine so far, only the little diagonal line (=Bugger) wont stay joined with the other lines.

Can anyone tell me, how to set up this line correctly?

Thx

Try constraining the angled line with a locked angular dimension to the base reference plane, and then constrain one end of the angled line to the edge reference plane.

This wont do the trick :-(. The lines are moving over the edge then as shown in the Pic. I´ll try to add the family directly (hope it works)...

Thx

I guess i tried pretty much everything with referenceplanes and -lines, but i still dont get it to work correctly. But i cant believe, that theres is no solution for this "simple" task... or could it... nahhh! I´ll keep on trying...

Try adding an additional reference plane or two with the ends of the angled line locked to it. Constrain the reference plane as needed to the width and/or base.

Hi,

thats with what i started in the beginning, but i keep running in errors, as shown in the pics. The line seems not to be able to hold both directions, it wants to move "along" the plane :-(. If i remove the diagonal line, everything is easy, but within it, trouble comes up the way...

Cheers

See if this works for you.

What I did was to start a new profile family (just have imperial template), add a reference plane on each side of the default center plane, constrain them with a dimension to be EQ from the center plane, and then add a dimension between the two new reference planes to define the profile's width.

I then copy/pasted your profile lines out of your family, placed them in the new family so the lines are centered in the family, and then constrained the left and right edges to the width reference planes, and the top and base to their planes.

Note that nothing else is constrained, and that it flexes without altering the radius edges or short lines.

Hi,

yeah great, that works fine. Once again: Think simple in Revit :-).

As it looks to me, the automatic constraints do the trick. As i need the family to be fixed on the left side and moving to the right, i just picked your copied family and removed the eq constraints an the middle ref-plane and it moves in this one correctly. Without any further constraints... Now im happy again :-). It didnt work in the original one, because i started with another profile and edited it, so the automatic constraints reacted differently.

Thx for your help, learned another lesson today :-)!

Cheers

just curious, how do you apply profile parameter in project environment like sweep, slab edge, etc.
i never used parameter in profile family before as i cannot "display" parameter of profile family in project environment, maybe i'm wrong or missed something?

edit: ic, for type list in project environment, but cannot change parameter value at project level like creating new profile type

Yes i have run into this issue as well. I open the original family to change the value of the parameter.

Hi,

i use the profile for nested families. You can choose the profile in the project browser and open the properties. Here you can pick the added parameter and link it with another parameter from your familiy. See pics. (sorry for the german dialoge, but i guess you will find it anyways...). Hope i could help :-).

You can edit the Profile values in the project. In the Project browser, go down to the bottom where Families are, and find Profiles. Expand the Profile in question, right click on a family type and go to properties. Or, duplicate it and make a new type.

Can a regular plygon like hexagon, octagon etc profile be parametrized ?

[aggockel50321]

You can also set up "types" within the family, which you can see at the project level..

thanks Max and Aaron, i didn't know profile/family properties can be accessed/modified through project browser before, man, you can always learn old/new tricks here and there from least expected angle!

Any profile can be parameterized.

More and more, i use the Project browser for everything and the type selector for nothing. The type selector is slow to open, and a pain to cycle through. If your office content is set up with a naming convention that makes it easy to decipher things when scanning quickly, the Project Browser is a Godsend for editing things.

Especially given some quirky limitations like:

1. You cant duplicate a wall type in Edit Group mode, but you CAN if you do it from the browser.
2. The "dead space" in the type selector will actually cancel out the type selector and not change types, so if you *miss8 during selection thats annoying, but the Browser has everything tight around the text.
3. The Browser seperates by Revit catagory, and the type selector still doesnt. Why that is, boggles my mind.

I made a Parametric octagon profile. Is there any easy method to constrain or this is OK ? Profile is attached. If there is a way to complete a polygon by simply entering number of arms & subscribe circle radi. ?

Ihave made a semi circle parametric profile, loaded into a column for sweep. Type parameter "Dia" is not nesting with the column. Where is the fault ? How can I control the dia of profile from column family. The column family under process with loaded profile is attached. If I use "Dia" as instant parameter in profile family what will happen ?
