AutoCAD 2013 :: How To Create Array Of Auditorium Seating
Dec 11, 2013
I am trying to find the best way to accomplish the task of populating an auditorium section with chairs. So far, I have created the arc path of the section and then offset each row the specified distance. From there I place a copy of the chair at one end of every path and then use the PATH Array tool in AutoCAD LT 2013. While this works, it doesn't seem to be very efficient (can actually be a royal pain, if changes are required) and was wondering if there is a better way to accomplish this goal?
What I would like to do is to use the POLAR Array tool and just work from the first row. That way, I could maintain all the necessary associativity and edit the array as a whole. However, this tool doesn't appear to offer the option of changing the quantities on successive rows, which led me to the above approach.
How I could use the tools differently, or has an exchange app that will accomplish what I am looking to do.

I'm trying to use the PATH array feature on 2013 to array stairs, and I can't get the array to be 100% accurate. It seems like CAD rounds the decimal to the nearest 3/4" which could be causing the problem.
I set my run to 10.5" and rise to 7.25", array along the angle of the stringer, and there's always a small overlap on the stairs. The "distance between" should be 1'-209/256" and CAD rounds it to 1'-3/4" which is where I believe the error is. Is there any way to fix this or array this correctly? Otherwise...back to the COPY method I suppose.

I am trying to create a parametric seating row with a Generic Line Based family.
If you check the file for the Length (default) parameter, I am multiplying it by the Arm Distance (600mm) so that the pattern repeats while I stretch out the line.
=Chairs * 600 mm
I want to add a parameter for the Arm Distance linked with the actual seat so that if I make the chair wider the pattern would adjust accordingly.
=Chairs * Arm Distance3
This way I could adjust the chair width and Line Based family all at once. However, I am finding that when I add "Arm Distance3" to the equation the Line Based feature stops working.

Rhino allows for two-rail curves and extrusions, is there anything similar in Autocad2013? I'm working on a trellis that has an undulating, slatted top - I can array the slats along one spline/polycurve, but figuring out how to rotate them to match the secondary angle/curve (it twists) is proving to be really difficult. Rotate3D I have trouble with (crossing different faces/USC which confuses me), and doing so for each slat is going to be exceptionally time consuming.
Is there a way to array a form along two paths, so that the pieces automatically adjust to match the needed angles that both rails define?

I have a base(blue) with an array(orange) positioned on a face.
When I select all & UNION the whole geometry becomes orange & I would like it to become blue.Selecting the base first then the array doesn't seem to work.

I am currently trying to draw a football stadium and I have copied the seats along the rows by using the array command. When I click on one seat it selects all the seats from the array. Is it possible to just select one seat incase the other stands don't have the same amount of seats?

I am trying to do a polar array of a small circle within a large circle. I chose the center point of the large circle as the center point of the array, but for some reason the smaller circles are not in perfect array as some one them slightly overlap the larger circle. Is there some way to calibrate it correctly?

I wish to control an array within a block (see jpg). Basically, I have a series of circles which I want to fix to Distance1. I want to control the distance between the circles with an expression called 'centers' (say 80mm). When I change the length of Distance1 in the Properties-tablet to say 600-mm, I want the array to follow the dimension.
When I select the array, the fx button next to the column distance on the array-tablet is greyed out. If I were using Revit, I would apply a dimension and give it a label which I would manipulate in the identity-table. What should I do in AutoCAD to achieve the same result?

My vision is when someone inserts "block A", a promt will come up and ask "how many of "block A" do you need?" Based on how many you need, it will insert the block along with the arrayed amount the user has typed in.

There are different results when executing polar array using the 'classic' method and the array using ACAD's standard array. I tend to revert back to the classic array as I find this more user friendly and tend to use this one over the standard ACAD array. Which methods are preferred by other CAD users ? I was wondering if any other CAD users prefer any other 'classic' functions over the standard ones. I sometimes use 'classiclayer' as well because of a display issue, not sure if this is a common bug that other users have found too ?

I was trying to figure out how to edit an array to either remove all the array objects outside of a shape or to fill in a shape with objects.
For example, I created a rectangular array of dots and want to remove the dots such that it makes a circle (or triangle if that's possible?). There are reasons that I can't use the polar array to make the circle because I need certain parameters that really I can't replicate. Also, selecting each point is too tedious and really not efficient (though it could be done eventually, but I don't want to waste a ton of time).

I've been trying to create a stair block that will automatically adjust the riser height to to suit the total vertical rise of the flight, but am having issues.
I drew two 'tread/riser' Plines, and constrained the daylights out of them. By stretching the grip for the 'Total Rise' constraint, the risers adjust nicely, while the treads remain at their desired 11" depth.
My problem is that when I try to create an array of the tread/riser, (using a linear parameter aligned with the slope of the stair) I can't get the 'column' width to change as the risers change height. Instead the value remains constant, and the arrayed copies don't connect with each other.
Any way either to fix this so that that the copies connect 'head-to-tail'?

I have a polyline path and a rhombus. I will like to array the rhombus along the polyline path. As you can see from the attached file, as the object rotates along the path, it shift off the path such that the distance between the rhombus and the path changes esp at the turn. How can I keep this distance between the rhombus object and the path constant?

I'm trying to create a Dynamic Block of an 3/4" x 3/4" aluminium angle with holes:
Depending on the length the number of holes will vary.
The distance between each holes need to be somewhere between 8" and a maximum of 12".
The holes must be centered and start from 1 1/2" up to 2" from each ends.
Each distance must be not more precise then 1/16" (no rounded off dimensions)
I'd like to simply drag the handle of the linear parameters (No lookup or visibility for 2 hole, 3 holes, 4 holes etc.)

Looking for a method of selecting multiple blocks that have been arrayed within a drawing. I have tired with filter and qselect however there is no way to filter out blocks by name contained within an aray. Would be great if there was a .lsp routine or arx file that could deal with this.

Okay, I'm new to associative arrays, I'm attaching a drawing so you can see what I'm trying to accomplish with this. I'm doing an elevation view of a slab that has a cross section of the rebar. I've shown one of the bars spanning from left to right, represented by a rectangle, and the cross section of the bars running front to back represented by circles. You can see what I'm trying to show here. In the drawing I've attached, the top three sketches are examples of how this would look if it were working correctly.
What I'm trying to do is create an array (of circles) that will stretch to the length of the bar spanning left to right. I want the quantity of items in the array to automatically change based on the length of the bar and the spacing of items, so if there is 6" of spacing between the items instead of 12" it will automatically add twice the amount of items to fill in that space. I've been trying to use a path array, and it isn't working the way I want. I'm not familiar with rectangular arrays, so not sure what to do there either.

I've tried using the union tool in AutoCAD 2013 as well as the Boolean join function in Inventor Fusion 2013. In AutoCAD it doesn't let me select more than one object (says that the array is the only object and that individual unit blocks are duplicates). In Inventor Fusion I can't seem to get the hand of selecting the target & tool bodies.
