AutoCAD Dynamic Blocks :: Constraining Move Action To A Single Plane?

Apr 1, 2012

For our office I'm trying to figure out (so far without success) how it might be possible to constrain movement of a block's geometry to a single plane?

I can use a stretch grip but that will mean you can go in one direction only (positive) not negative, I want the freedom to be able to move backwards and forwards in the X-Plane.

Block I'm working on (progress so far) attached. It is designed to display height relative to a datum point in the block, and for use in drawings so you can place it all over and pick up levels to top of things like steels.

The block allows the use to pick the stretch grip to go up, so the objects moved will be to a point which will be relative to the base point of the block, which will be set at a datum level for the drawing. Relative to the base point a field will extract the y-coordinate of an object in the block, add a suffix of mm, that will then be the level relative to the base point.

I want the move command constrained to move the block geometry in the drawing but only in the x-plane; if the entire block moves accidentally in the y-plane it will also move the base point also, which destroys the idea of measuring against a fixed datum.

AutoCAD Dynamic Blocks :: Link Move Action To Visibility Parameter

Sep 12, 2012

I've got a block with 2 lines of text, the second line being optional.  If the second line is omitted, the first line should be moved down, so it's centered.

I can handle the second line being omitted with a visibility parameter.  And I can handle the first line being moved down with a move parameter.  But how can I link the two?

Ideally, I'd be able to re-use the line 1 attribute and display it in whichever place was correct, but that doesn't seem to be possible.

AutoCAD Dynamic Blocks :: Adding One Action To Dynamic Blocks

Mar 15, 2012

I have created a dynamic block with several visiblility states. The block works great for what I need it for. however, I am trying to add one more action to the block but am having issues.

This block is essentially a 24" retail cabinet with the visibility states showing the different drawer and shelf configurations. I want to be able to lengthen the cabinet in 24" increments and have the visibility show for each 24" section.....e.g.  I want a 10' cabinet so I bring in the 24" starter block. Then stretch the cabinet to the 10' mark, then I can chose any drawer/shelve config for each 24" section (they are all different).

I can get the block to stretch in 24" sections....no problem.....i just want the visibility state to be duplicated as well for each section. Now as it stretches, there is only one Vis state and it only populates the first cabinet.

I could do this by copying the block over and over 5 times.....but I am hoping there is a way to make this dynamic.

AutoCAD Dynamic Blocks :: Link Dynamic Block Custom Rotation Action

Mar 22, 2013

So I've done a reasonable amount of work with dynamic blocks. I have a block with a rotation action and grip to arbitrarily align it.  However I realized when trying to combine it with an alignment grip (which actions on the basic or fundamental block rotation angle) that there didn't seem to be a way to some how link a dynamic block rotation action or one of the custom angle properties to a the fundamental block rotation angle.  Thus there are two additive rotations at work; the dynamic block one with its grip and the fundamental rotation property.

This can cause some confusion when one person aligns with the grip and another via rotating the block's fundamental property and would also be problematic in the generalized sense if one was trying to select or programmatically read back the net angle alignment.

AutoCad :: Dynamic Blocks - Action Bar Visibility

Jul 10, 2012

I have a rather unusual problem. I'm using AutoCADLT2013. I have a dynamic block, with chained parameters. The block works perfectly, however, I'm expanding the contents, and trying to add more polylines to existing actions.

I have the following Actions showing: Stretch, Lookup, and Visibility. All of these actions are on unchained Parameters. The 2 Actions I'm missing are Arrays, both on chained Parameters with no Grips.

I've used ACTIONBAR on both Parameters (Show, then Hide, then Show again, I don't want to use Reset!), yet the Action Bars still won't show!

I've been messing for nigh on 2 hours and I can't figure it out. To make things worse, I can't use the Parameter Manager, due to it disappearing when in Block Editor.

I really don't want to have to start again, as it was a right pain in the rectum to get to work right.

AutoCAD Dynamic Blocks :: Array Action With Text

May 22, 2013

i work at a small structural firm and am about the most experienced cad user here, which isn't saying much.  I have never wrote any LISP's or anything, but have created many dynamic blocks and have edited some programing my boss got from a previous employee for adding dropdown menus with blocks/layers/etc.  Just so you know my level of knowledge when it comes to answering my question. Also I am limited to using 2009 but other co-workers have up to 2013 so i would like this to work for all users. And i have done a bit of research but based on everyone elses level of knowledge am finding a lot of conflicting info and solutions that, to me, are in another language.

So I have a table that is created using polylines and text.  It's a funky shape and AutoCAD's tables are a pain for it. i have created a dynamic block where i can array the rows down and the columns left.  The issue is, i would like the test to come with each row, but still be editable once the block is done.  I have figured out if row one is composed of 5 columns of text put into a single attribute, it is fine. But once you use the array action, to say 3 rows (including now 3 sets of attributes) they are not editable.  So what is the work around, if there is indeed a work around?  

the two option i see are to only array the rows and columns and left the text outside that block and manually copy it done to how ever many rows the user needs....  Or to have 2 blocks come in together, one as described before, and the other which just arrays the text and then i explode it to edit each line.. but then if you later choose to addd another line you would be left with doing that manually anyway..

AutoCAD Dynamic Blocks :: Location Of Action Bars

Sep 17, 2013

I'm having an issue with the action bar locations. While I am creating the dynamic block, the actions all attach them selves to their respective parameters. The problem is that somehow at some time, the action bars change their mind and all lock down to the origin. All my action bars and icons are on top of each other. Is there a parameter to adjust to make the action bars move back to their parameters? Images are attached.

AutoCad :: Hatch In Dynamic Blocks With Stretch Action

Jul 15, 2013

I foolishly thought i'd sorted making hatch work within a dynamic block that requires user input to set length and width of block...the hatch would fill to the revised size when the user sets the length and width in the properties dialogue...woohoo. Off I go home from work having defeated the nemesis of the day.

Open up my drawing today and can I get the hatch to act as it did yesterday?

I built my block (a simple rectangle all told) added my parameters in block editor. length and width linear actions with 0 grips as I don't want stretching by grips. Added the stretch actions. Tested the block (without hatch)...working. Only then did I hatch, so into block editor and using associative, send to back, normal island detection and selecting the rectangle to hatch. tested block ...working. great. Inserted the block into new drawing...working.

Opened AutoCAD today...Not working...hatch remaining as original size

Tried building new block exactly as I did yesterday...no joy...

On a side note...it works if I leave grips on but only if I use the grips to activate the hatch (it still doesn't work by just typing into properties though) that's not going to cut it as I don't want to be telling everyone to wiggle the grips so to speak.

AutoCAD Dynamic Blocks :: DB Stretch Action Isn't Working Correctly

Oct 4, 2013

I cleaned up my block and I am trying to use a field to reference a polyline for it's overall distance. The distance changes with my lookup action. After rotating and going back and forth from "On" - "Off" - "Both Off", then back to "On", the red polyline doesn't stretch back on it's original plane.

AutoCAD Dynamic Blocks :: Scaling Action Does Not Produce Expected Results

Jun 10, 2013

I am relatively new to dynamic block. I have generated a dynamic block that has four hole. I have HDistance and YDistance linear parameters set with mid point as their base location and action assigned so that they spread apart equally in horizontal and vertical direction and it works fine.

I am now adding another linear parameter (to change hole diameter) by trying to assign scale action, to increase or decrease hole diameter of all four holes simultaneously.

AutoCAD Dynamic Blocks :: Prepare Linked Chain Around Defined Path - Rotation Action

Jan 11, 2013

I need to prepare a linked chain araound a defined path. (Please have a look at the attached drawing) My idea is to have one element of the chain defined as a dynamic block and to manually "rotate" one side of the chain element. After that inserting the next element (previously aligning the user coordinate system) and "rotating" the right part again to the next position...

After doing the rotation, the block definition will change and the next block will be "disformed". So far no big problem, but the grip of the rotation parameter will stay there and I am not able to "rotate" the right part back into the old position (0 degree).

AutoCAD Dynamic Blocks :: Limit A Stretch Or Move But With A Variable Value?

Dec 17, 2011

I would like to find a way to give a maximum and minimum length to a stretch (or move) but without absolute values.

simplified example of my block:

I have 2 squares, of which one big on, and a smaller one within the bigger one. I want to be able to stretch both squared indefinatly (no problem there), but the big square may never become smaller than the small one, and the small one may never become bigger than the big one...

In other words: the inside square should always stay inside the bigger one, no matter the size of the squares.

The problem with this block is that I have a hatch pattern between the squares, and as soon as i stretch the small square outside (or equal) to the big square... the hatch pattern 'crashes'.

AutoCAD Dynamic Blocks :: Stretch / Move / Array Block

Jul 31, 2012

I need this block to do the following:

1. Move the right piece so it ends at 3', 4', & 5'.
2. the move right hook and 'backing' to stretch/copy (or array) so it adds a hook to the right and fills in the backing.

so this means that a 3' gets 4 hooks, 4' gets 5 hooks and 5' gets 6 hooks.

3. the block as shown is the smallest configuration with 3 hooks.

I could just set up a visibility and draw each one at it's appropriate length but I'm trying to keep this simple block to a min size. If all else fails, that's the route I'll take.

I've tried a couple different configurations and I keep getting duplicates or the end piece doesn't move the correct distance.

AutoCAD Dynamic Blocks :: Move Attributes In Constraint Parameter Environment

Mar 12, 2012

I have a dynamic block that I am trying to add some pretty basic functionality to (at least it seems like it should be simple!). Since I’m still relatively new to DB’s, I figured I’d give some background on what I’m trying to do, cause maybe it could be done with a much easier approach than I have come up with. So if you don’t feel like reading the details, see the fourth paragraph for my actual question.

The block is a sheet reference annotation (that shows:  SheetNum/TotalNumOfSheets)  that we typical put in the notes section of our construction drawings.  It looks nice when the text (which are attributes), lines up with the text in the note (usually Mtext, but sometimes a Mleader). So I constantly find myself completing the tedious task of placing the block at the insert point of the Mtext (which is always justified LEFT TOP), and then calculating the distance down to line that I want the block to line up with.

So what I want the block to be able to do is to be able to have the user grab the block by its basepoint, place it at the insert point of the Mtext object, and just enter the text height of the Mtext note, the line space factor, and the target line of the note that the sheet reference block should line up (the input would all be done via custom block properties in the Properties Palette).  And since we almost always use a text height of 0.125 and Line Space factor of 1, those will be the defaults, and really the only thing that would need to be entered would be the line number of the Mtext that the annontation should line up with.

I already figured out most of the constraint parameters necessary and calculated the offset equation using custom parameters. I have all the linework moving correctly using the vertical constraint parameters, however, I cannot figure out how to get the Attributes to move along with the linework. I know how to move text and attributes using Action Parameters, but I can’t do it with Constraint Parameters. So I figured that maybe I could chain an Action Parameter to the Constraint Parameter, but I couldn’t figure out how to do this either. Also, I am using visibity states and would like the visibility grip to move along with everything else as well.

My block is attached. I used some lines for the Constraint Parameters to be associated with, but they are only there for the block to operate correctly, therefore they are invisible in both of the visiblity states. Probably not the best way, but it works.

AutoCAD Dynamic Blocks :: Root Radius - Move And Scale Actions

May 23, 2013

[URL] how to add a dynamic radius, with reference to the Move and scale actions.
 
"1. Set the Radius to Independant and move the center point to the center of the radius"

"2. Add the Scale Action to the Move Action"

"3. You already noticed the angle of the stretches (45, 315) needing to change and the Move multiplier of 1.414"

I am trying to design a column block, but following  the above instructions for the root radius the radius moves when I test the block!

1. "move the center point to the center of the radius" What does this mean. I am selecting a liinear parameter, selecting the mid point of the arc first and then the arc center point.

2. "Add the Scale Action to the Move Action". How do you add the scale action to the move action.

AutoCAD Dynamic Blocks :: Architectural Detail - Move And Stretch Actions?

AutoCAD Dynamic Blocks :: (Section) Cut Marker With ATTDEF - Can't Move Ends Independently

May 25, 2012

I've got a section marker (the letter designation with arrowheads pointing in the direction of the cut) that I cannot get to behave correctly.

When I set a parameter to one end with a move action, in order to have the arrowhead and attdef for the letter designation move upwards, all is well. When I try to do the same to the other end, the letter desingation attdef will not move.

Neither attdef is set to "Lock Position", so I'm puzzled why one works and the other end does not. I've tried a move action on both ends and a combination of move/stretch, but I can't get it to work.
